The pumpkin seed membrane (PSM), which is high in water retention in the study, was recycled as waste, intended to be used in terms of target-non-target creatures and to determine its effect on resistance formation. Nowadays, when fat intake is steadily increasing through nutrition, increased use of fat makes an individual vulnerable to stress. The study determined the effect of additional taken waste/nutrients on oxidative stress in obese individuals. The fatty diet and pumpkin seed effect were trialed in the model organism in the study. The amount of Malondialdehyde (MDA) and total oxidation (TOS) and total antioxidant effect (TAS) and glutathione-S-transferase (GST) activity in larvae, pupae, and adult of Drosophila melanogaster were calculated by adding different proportions of PSM (0.05-2 g) and fat (20%) to the diet. According to the data obtained: It was determined that the period with the highest oxidative stress index (OSI) is the pupae (pupae> larvae> female> male), the amount of lipid peroxidation (MDA) is higher in females, moreover, the third larvae is the most resistant stage. The results have shown that waste of seed mambrane can't be useful in vivo as a nutrient due to usage limitation.

“…Similarly, in fruit y, Drosophila melanogaster, although both larval and adult diet affect adult body size, poor larval diet causes a more severe reduction in adult body size than a poor adult diet. Even so, a good adult diet is able to mitigate the effect of a poor larval diet (Poças et al, 2020). Effects like these are generally thought to result from variation in how individuals allocate resources to storage versus development (Boggs, 2009;Fischer et al, 2004).…”

How Does Access to Water at Different Life-Stages Affect Male Investment in Reproduction and Survival?

Holometabolous insects have four distinct life-stages – eggs, larvae, pupae and adults. Active resource acquisition generally occurs during either or both the larval and adult stages. Previous research on the acquisition of food resources in holometabolous insects, has shown that resources acquired during each of these life-stages can differ in how they are allocated to different traits, and how they affect fitness. In addition to food, water is also an essential resource needed for a range of biological processes that enhance fitness. Yet, how water acquired at different life-stages affects key fitness traits is still not clear. Here, we manipulated both developmental and adult water availability of male seed beetles (Callosobruchus maculatus) to explore how water acquired at each life-stage affects a range of fitness related traits, including body mass, ejaculate weight, mating behavior and lifespan. Our results indicate that the juvenile environment had little effect on body weight, ejaculate weight, ejaculate replenishment or lifespan, but did influence male mating behavior in both early and late adult life. This contrasts with the adult environment, which had strong effects on weight loss, ejaculate size and lifespan but little effect on mating behavior. Males with access to water during adulthood transferred larger ejaculates during their first mating, lost less weight as they aged, and lived longer. These results suggest that water acquired during development and adulthood are allocated differently to a variety of fitness traits across life.

“…Food availability in early life may be particularly important in insect larvae that consume food voraciously throughout most larval stages (Edgar, 2006;Tennessen and Thummel, 2011). Nutritional restriction during larval stages has been shown to delay larval development, as well as reduce adult body size, reproductive performance, and lifespan (Beadle et al, 1938;Dmitriew and Rowe, 2011;Runagall-Mcnaull et al, 2015;Poç as et al, 2020). Food consumption in larvae is essential to accommodate the growth necessary to achieve metamorphosis.…”

Aggression Is Induced by Resource Limitation in the Monarch Caterpillar

et al. 2020

Food represents a limiting resource for the growth and developmental progression of many animal species. As a consequence, competition over food, space, or other resources can trigger territoriality and aggressive behavior. In the monarch butterfly, Danaus plexippus, caterpillars feed predominantly on milkweed, raising the possibility that access to milkweed is critical for growth and survival. Here, we characterize the role of food availability on aggression in monarch caterpillars and find that monarch caterpillars display stereotyped aggressive lunges that increase during development, peaking during the fourth and fifth instar stages. The number of lunges toward a conspecific caterpillar was significantly increased under conditions of low food availability, suggesting resource defense may trigger aggression. These findings establish monarch caterpillars as a model for investigating interactions between resource availability and aggressive behavior under ecologically relevant conditions and set the stage for future investigations into the neuroethology of aggression in this system.
