“…Faster larval development rates on artificial diet compared to host plant material has also been reported for Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) (Abbas Ali et al, 1990). Pupal development rates were similar under both dietary regimes ( fig.…”

The developmental rates and fecundity of two important African maize pests, Sesamia calamistis Hampson and Eldana saccharina Walker, were studied under constant temperatures and with two larval diets. Five temperatures (15°, 20°, 25°, 30° and 35°C) were used to investigate developmental rates and three temperatures (20°, 25° and 30°C) were used in fecundity experiments. Larvae were reared on maize stem cuttings and on artificial diet. The developmental period for S. calamistis on artificial diet required over 700 degree-days (DD); eggs needed 122 DD above a threshold of 9.7°, larvae required 383 DD above 12.2°C and pupae 204 DD above 10.2°C. The developmental period for E. saccharina on artificial diet was 665 DD; eggs required 125 DD above 9.1°C, larvae 400 DD above 10.6°C and pupae 140 DD above 8.8°C. On artificial diet both species developed faster and had higher threshold temperatures for larval development than when reared on maize stem cuttings. Pupal development rates did not differ between artificial diet and maize stem for either species, although developmental thresholds were marginally lower on artificial diet. S. calamistis averaged 250-690 eggs/female although some individuals produced more than 1000 eggs. Adult females lived 5.7 days at 30°C and 10 days at 20°C. E. saccharina females produce more eggs and lived longer than S. calamistis females. Average fecundity for E. saccharina was 470-620 eggs/ female, but several individuals produced more than 1200 eggs. Adult females lived 6.6 days at 30°C and 14.6 days at 20°C.

“…Knowledge of the nutritional value of available host plants is important for developing practical management strategies, because the economic status of polyphagous insects is influenced in part by the nutritional quality, as well as by the relative abundance, of host plants (Ali et al, 1990). Variation in head capsule widths and associated instar numbers among host plants would then be related to variability in nutritional quality as the season progresses, and connected with the particular phenology of each host plant.…”

“…The results of our study illustrate the difficulty in developing predictive phenology models for S. litura, which has a wide host range and different biological responses (e.g., developmental time, instar weight, instar numbers) to each host. Therefore, parameter estimates for phenology models should be based on data obtained by rearing larvae on major host plants in specific geographical areas (Ali et al, 1990). These phenological models will help in developing accurate sampling and efficient chemical control programs.…”

“…One such negative effect of increased temperatures and heat waves is an increase in parasitoid development times [10], [28]. Elevated temperatures can also decrease larval development time [14], [30], [38], [39] and increase performance [30]. These combined temperature driven changes could negatively affect natural enemies by causing asynchrony between herbivore hosts and parasitoid development, resulting in a greater potential for herbivore outbreaks and lower plant biomass [40].…”

Effects of CO2 and Temperature on Tritrophic Interactions

There has been a significant increase in studies of how global change parameters affect interacting species or entire communities, yet the combined or interactive effects of increased atmospheric CO2 and associated increases in global mean temperatures on chemically mediated trophic interactions are mostly unknown. Thus, predictions of climate-induced changes on plant-insect interactions are still based primarily on studies of individual species, individual global change parameters, pairwise interactions, or parameters that summarize communities. A clear understanding of community response to global change will only emerge from studies that examine effects of multiple variables on biotic interactions. We examined the effects of increased CO2 and temperature on simple laboratory communities of interacting alfalfa, chemical defense, armyworm caterpillars, and parasitoid wasps. Higher temperatures and CO2 caused decreased plant quality, decreased caterpillar development times, developmental asynchrony between caterpillars and wasps, and complete wasp mortality. The effects measured here, along with other effects of global change on natural enemies suggest that biological control and other top-down effects of insect predators will decline over the coming decades.
