“…Therefore, the pattern of thermal reaction norms may depend on the quality of food, as the energy requirements of organisms vary with temperature [1]. Such a relationship was confirmed by a significant interaction between temperature and diet in studies of insects reared on plant or artificial diets [61][62][63][64][65][66][67][68].…”

Temperature and food quality are the most important environmental factors determining the performance of herbivorous insects. The objective of our study was to evaluate the responses of the spongy moth (formerly known as the gypsy moth) [Lymantria dispar L. (Lepidoptera: Erebidae)] to simultaneous variation in these two factors. From hatching to the fourth instar, larvae were exposed to three temperatures (19 °C, 23 °C, and 28 °C) and fed four artificial diets that differed in protein (P) and carbohydrate (C) content. Within each temperature regime, the effects of the nutrient content (P+C) and ratio (P:C) on development duration, larval mass, growth rate, and activities of digestive proteases, carbohydrases, and lipase were examined. It was found that temperature and food quality had a significant effect on the fitness-related traits and digestive physiology of the larvae. The greatest mass and highest growth rate were obtained at 28 °C on a high-protein low-carbohydrate diet. A homeostatic increase in activity was observed for total protease, trypsin, and amylase in response to low substrate levels in the diet. A significant modulation of overall enzyme activities in response to 28 °C was detected only with a low diet quality. A decrease in the nutrient content and P:C ratio only affected the coordination of enzyme activities at 28 °C, as indicated by the significantly altered correlation matrices. Multiple linear regression analysis showed that variation in fitness traits in response to different rearing conditions could be explained by variation in digestion. Our results contribute to the understanding of the role of digestive enzymes in post-ingestive nutrient balancing.

Effect of host plant species and temperature on the development and survival of the plant bug Closterotomus trivialis (Costa) (Hemiptera: Miridae)

et al. 2022

Nymphal development, mortality and adult longevity of the plant bug Closterotomus trivialis were studied on two of its major crops (Olea europaea L. cv. 'Koroneiki' and Citrus sinensis L. cv. 'Washington Navel') and four non-crop host plants (Mercurialis annua L., Urtica urens L., Parietaria diffusa M. et K. and Sinapis alba L.) under laboratory conditions (15, 20, 24 and 27 °C ± 0.5%; 60 ± 5% RH; 16L:8D h photoperiod). Results demonstrated that C. trivialis can successfully complete its development on all tested host plants and temperatures, except for U. urens at 15 and 20 οC. Mortality rates were generally higher on U. urens, P. diffusa and olive than on S. alba, M. annua and sweet orange. Both temperature and host plant significantly affected the nymphal development of C. trivialis. Specifically, host plant affected the development of nymphs at lower and higher temperatures (15, 20, 27 °C) but not at the optimum (24 °C) for its development temperature. Adults of C. trivialis lived longer on sweet orange, M. annua and S. alba in most tested temperatures compared to U. urens, P. diffusa and olives. Overall, these results suggest a better suitability of M. annua, S. alba and sweet orange compared to U. urens, P. diffusa and olive which were proven to be less suitable host plants, covering partially the nutritional needs of C. trivialis. The estimated lower temperature developmental threshold based on the linear model for C. trivialis was found to be lowest on M. annua (3.30 °C) and highest on P. diffusa (10.7 °C). Τhe assessment of the nymphal development in various host plants and temperatures is particularly important for understanding the biology of C. trivialis and provides useful information to optimize its management strategy under integrated pest management system.
