Abstract: We asked if the structural heterogeneity of a laboratory arena differentially affected the abandonment of the plot, residence time, locomotory rate, pause duration and turning rate of adult Eriopis connexa and Hippodamia variegata (Coleoptera: Coccinellidae). We simulated an increase in heterogeneity by distributing vertically-oriented toothpicks in a circular arena: one control (without toothpicks), one uniform plot (toothpicks every 1 cm) and one random plot (randomly distributed toothpicks). E. connexa did not discriminate between plots in their residence time, but H. variegata remained longer in the uniform and longest in the random plots. H. variegata only stayed longer than E. connexa in the random plots. This resulted because adults of H. variegata were stationary for longer periods, moved more slowly and less linearly and explored a higher number of toothpicks than adults of E. connexa in more heterogeneous environments. Thus, the physical structure of the environment differentially affects the movement patterns of insects. Eriopis connexa seems to be less sensitive to structural heterogeneity than H. variegata.

            NAL call number: QL461.E4

Abstract: 1. Burying beetles inter small vertebrate carcasses that ultimately serve as a food source for their developing young. The male remains with the female on the carcass after the brood has been produced, purportedly to aid in the feeding and protection of larvae. However, numerous laboratory experiments have failed to demonstrate a beneficial effect of the male on the growth and survival of offspring. 2. A potential difficulty with laboratory studies is that beetles are typically held under relatively benign conditions, protected from the biotic and environmental challenges that they normally encounter. In nature, males may enhance offspring survival by aiding the female in ridding the carcass of mould, and by helping to preserve the carcass through the secretion of antibiotic substances in the beetles' saliva. To examine more rigorously the potential benefits of male parental care, an experiment was conducted under field conditions in which the reproductive output of male-female pairs was compared to that of single females. 3. Beetles were induced to bury carcasses in soil inside rigid plastic tubes that had been inserted into the ground. The experiment was a paired design involving pairs of sisters reproducing in adjacent tubes; one sister reproduced alone, whereas the other reproduced with the assistance of a male. Soil cores were recovered about 1 month later, and examined for viable pupae. 4. There was no significant difference in the number of offspring produced by single females and those reproducing with the assistance of the male, nor was there any significant difference in total brood mass. These results suggest that any benefits of extended male residency on the carcass do not stem from male participation in carcass maintenance or provisioning young.

            NAL call number: 421 J825

Abstract: Rates of water loss were determined for four Coleoptera species: the herbivores Hydromedion sparsutum and Perimylops antarcticus (Family Perimylopidae) and the carnivores Trechisibus antarcticus and Oopterus soledadinus (Family Carabidae) collected during summer from a range of terrestrial habitats at South Georgia. A recording microbalance enabled measurement of individual weight loss with time in < 5% r.h. at 10, 20, 30 and 35 degrees C. Adults of T. antarcticus had significantly higher rates of water loss than any other species over all temperatures. Individuals of both herbivores exhibited the slowest water loss rates under the experimental conditions. Within species, rates at 10 or 20 degrees C were slower than at the higher temperatures. Adult P. antarcticus had significantly greater amounts of body water than adult H. sparsutum for each of the four temperatures. Within species and life-stages of both herbivores, body water contents after drying at 10 degrees C were significantly lower than individuals dried at 30-35 degrees C, but no such differences were observed for the carnivores. At each temperature, rates of water loss were negatively correlated with initial live weight in all four species, but this was not the case within species or between adults and larvae. Maximum survival times during desiccation declined as temperature increased, but did not differ between species at 10 degrees C. Over 30-35 degrees C, survival times of both herbivores were significantly longer than either of the carnivores. Smaller insects (e.g. the carabids) had faster rates of water loss than the larger perimylopids under the same environmental conditions. The latter had greater resistance to desiccation than the former. It is suggested that the larger body water content of P. antarcticus enables it to resist desiccation more than the other three species, which correlates with its ecological distribution. Differences in water contents after drying individuals at low and high temperatures may be caused either by the water binding properties of cells and tissues or by reduction in energy stores in order to maintain metabolism at lower environmental temperatures causing a body weight loss. Whilst both herbivores show some physiological adaptations to drying conditions, it is suggested that the two carnivorous beetles may have adapted behaviorally to the South Georgia environment.

            NAL call number: 421 J822

Abstract: Entomologists and breeders have met with limited success in the development and release of insect resistant soybean cultivars. Although numerous germplasm lines resistant to defoliating insects have been released, only three cultivars have been made available to growers over the past 20 yr. Researchers have examined potential limitations of insect resistant soybeans, with most of the studies examining the negative impact of plant maturity. This study examined the relative resistance levels of four advanced germplasm lines during the vegetative, flowering, and pod-fill growth stages of soybean development. Resistance was measured by rearing Mexican bean beetle, Epilachna varivestis mulsant, on excised, field-grown leaves and comparing larval mortality and developmental periods. The study was conducted in two locations for 2 yr. In the 1st yr, mortality was significantly greater, and developmental periods lengthened, on the four resistant soybean lines compared with two susceptible cultivars during the vegetative and flowering stages; however, these differences were slight to nonexistent during the pod-fill stage. Although similar differences were evident the 2nd yr, the levels of resistance were greatly lowered. This reduction in resistance as the plants matured is comparable to that found by other researchers. The loss of resistance in the 2nd yr was unexpected and was attributed to much higher than normal rainfall in July at both locations. We discuss the consequences of lower levels of resistance in maturing plants and under conditions of high rainfall, both for breeding programs and field resistance as required by growers.

            NAL call number: QL461.E532

Abstract: The effect that harsh, variable desert temperatures might have on the structure and population dynamics of a guild of Bruchidae (Coleoptera) that feed in the seeds of mesquite, Prosopis velutina wooten, was examined in a 3-yr field and laboratory study. Metabolic rate, fecundity, longevity, developmental times, survivorship, and body size were measured across the temperature spectrum in which the species normally live. The 4 species that compose the guild-Algarobius prosopis (LeConte), Mimosestes amicus (Horn), Mimosestes protractus (Horn), and Neltumius arizonensis (Schaeffer) divide the use of the resource temporally. The first 2 species dominate resource use and overlap entirely in time, whereas the 2 latter minor species utilize opposite ends of the temporal resource spectrum. Of the two dominants, M. amicus functions as a physiological generalist, apparently sacrificing resource adaptation for greater temperature adaptation and very high reproductive output. In contrast, A. prosopis is well adapted to both the use of mesquite as a resource and also to the desert thermal environment. The 2 minor species seem to be less well adapted to both the resource and the environment. Temperature clearly plays a strong role in determining the structure of this guild of bruchids.

            NAL call number: QL461.E532

Abstract: In its natural environment, the Colorado potato beetle, Leptinotarsa decemlineata (say), colonizes plants that are distributed in patches. In such conditions, females must select oviposition sites that will provide sufficient resources for the survival of their offspring. The presence of conspecific eggs on the plant reduces the amount of resources available, so the density of conspecific eggs must be evaluated. In the laboratory, most females laid their eggs on the terminal leaflet of the highest of 3 leaves available to them. Feeding damage did not seem to modify the process of oviposition, and the presence of eggs did not change feeding patterns. In choice tests, egg clutches, hexane-washed eggs, yellow paper, and green paper reduced deposition of eggs on the treated leaflet, whereas hexane, white paper, and egg extract did not. Conspecific egg perception using visual cues, and possibly other stimuli, was demonstrated.

Abstract: Three independent studies were conducted on the effects of constant temperatures (0, 3, 6, 9, 12, 15, 18, and 25° C) with numerous exposure times (15 to 240 d) on diapausing embryos of the northern corn rootworm, Diabrotica barberi smith and lawrence. All three studies had similar results. The temperatures 15 and 18 degrees C appeared to enhance diapause development and subsequent diapause termination when compared with the lower temperatures (0-3 degrees C). However, the temperature range 9-12 degrees C was optimum for minimum mortality and maximum hatch at nearly all exposure times used. At this range and in particular 9 degrees C, hatch was as high as 60% after 180 d exposure. Exposures of 15 and 30 d produced minimal hatch, < 20%, at any temperature. Days to hatch tended to decrease as temperature increased but varied with experiment. Hatching time also decreased as exposure increased for all temperatures. Eggs exposed only to the developmental optima of 25 degrees C had < 20% hatch in all studies, and greater than or equal to 50% of the eggs were still in the diapause state at the conclusion of the studies. We concluded that most D. barberi embryos require low temperature to terminate diapause and complete embryogenesis. These studies support the hypothesis that D. barberi has a propensity to be continuously variable in diapause length. Also, variable diapause length has allowed this species to adapt to natural and artificial perturbations, in particular, crop rotation.

            NAL call number: QL461.E532

Abstract: Life history of immature maize weevils, Sitophilus zeamais motschulsky, was studied at 10-40° C and 43-76% RH. The optimal quantity of corn for minimizing density effects and the optimal observation frequency for minimizing disturbance effects were determined at 30° C and 75% RH. The quantity of corn (32-256 g) provided to five females ovipositing for 24 h did not affect duration of development, but the number of progeny produced increased asymptotically as the quantity of corn provided increased. Frequency of observation (from 1- to 14-d intervals) did not affect duration of development or number of progeny produced. Using moisture contents measured in the life history study, an equation was developed for predicting equilibrium moisture content of corn from temperature and relative humidity. Duration of immature development did not vary with sex, but did vary with test. This suggests that insect strain or chemical composition of the corn must be included as factors in a model predicting effects of environment on duration of immature development. Survival from egg to adult emergence was greatest at 95° C. Sex ratio of emerging adults did not differ from 1:1. The number of multiply-infested kernels was low at all environmental conditions, and survival from egg to adult emergence in these kernels averaged 18%. Maximum daily rate of fecundity, duration of development, and number of progeny produced were optimal at 30° C and 75% RH. An index of environmental suitability indicated that 30° C and 75% RH was the optimal environment for growth of maize weevil populations on corn. Implications of the results for managing maize weevil populations are discussed.

            NAL call number: QL461.E532

Abstract: The water loss dynamics and humidity preference of Rhynchophorus cruentatus (f.) adults were investigated. Total body water averaged 47 +/- 8% by mass, and cumulative loss increased with time at all humidities tested (0, 33, 63, and 100% RH) at 30° C. Death occurred more rapidly in low than in high humidities, at which time weevils had lost approximately 50% of their total body water. Cuticular permeability of weevils calculated from exposure to 0% RH for 2 h was 39.5 +/- 4.1 and 75.9 +/- 8.1 micrograms cm-2 h-1 mmHg-1 when surface areas were calculated using Meeh's formula and planimetry, respectively. When given a choice, R. cruentatus adults chose high over low relative humidity after exposure for 2 and 24 h. R. cruentatus adults are subject to desiccation under a drying environment and may use habitat location to conserve water.

Abstract: The influence of temperature and feeding on some important biological characteristics (longevity, preovideposition period, fecundity, lenght of cycle egg-adult) of Rodolia cardinalis (mulsant) (Coleoptera: Coccinellidae) has been investigated. On the basis of the achieved results, a rearing plan and storage is suggested to keep a stock culture of R. cardinalis at low cost, up to 220-240 days, managing temperature and food. This allows to maintain easily R. cardinalis during winter and to retard the normal laboratory rearing in spring, when the outside conditions are favourable to make distributions of the predator, if necessary.

Abstract: Host recognition and aggregation behavior in the black spruce beetle, Hylastes cunicularius erichson, were studied in choice experiments in the laboratory. The beetles tended to aggregate. Aggregation occurred at host material or at beetles and was independent of the sex of the beetles. Hidden host material was found by active host orientation. The beetles were attracted by several conifer species. In some experiments the beetles preferred the main host, Norway spruce, but Scots pine was also readily accepted. Sections of roots were chosen more often than stem sections. Fresh cuts on the host material enhanced attraction. No evidence was found to indicate the presence of an aggregation pheromone.

Abstract: In order to investigate a difference in number of eggs laid per female adult, and effect of temperature on reproduction and surviving period of female adults between Epilachna vigintioctomaculata (Ev hereafter) and E. niponica (En hereafter). One-pair rearing of the two species was done in the laboratory at different temperatures (20, 25 and 30° Centigrade). The results were as follows. [Ev] There was no significant difference in the number of eggs laid and the number of egg masses per female adult among three temperatures. However, the surviving period of female adults became longer at 20° Centigrade and shorter at 30° Centigrade, and the number of eggs per mass became larger at 20° Centigrade and the lowest at 30° Centigrade. It was conceivable that temperatures of 20° Centigrade and 25° Centigrade were suitable for reproduction and surviving of female adult of Ev and that of 30° Centigrade C was unsuitable. [Ev] The number of eggs laid and the number of egg masses per female adult became larger and surviving period of female adult was longer at 20° Centigrade and 25° Centigrade. Further, the index of fecundity was the highest at 25° Centigrade and the lowest at 30° Centigrade. So, it might be considered that temperatures of 20° Centigrade and 25° Centigrade were suitable for reproduction and surviving of female adult of En. It seemed that temperature of 30° Centigrade was unsuitable for reproduction and surviving of Ev. From the comparison of these results of the two species, it became clear that there was a difference in reproductive performance between the two species. It is conceivable that the difference in reproductive performance between the two species becomes an important factor responsible for population density of the two species in the field.

            NAL call number: 421 J822

Abstract: The described rearing method approximates the natural environment for larvae of Diabrotica virgifera virgifera leconte more closely than do previous methods: eggs are in close proximity to corn roots when they hatch, neonate larvae are not handled, and larvae are reared in soil. In addition, the method is less labor-intensive. Our quality-control samples indicate a mean (+/- SD) return of 53.0% +/- 5.0 from eggs to adults and a mean return of 72.7% +/- 10.2 from neonate larvae to adults. Adult females have a mean head-capsule width of 1.22 mm +/- 0.4. Moreover, our new method for handling adults, both before and during mating, has resulted in a significant improvement in mating: percentage of mated females increased from a mean of 66 to a mean of 95%.

Descriptors: Diabrotica virgifera, larvae, containers, rearing techniques and methods, eggs close to corn roots, adult handling.
