Effect of Diet Quality on Survival and Reproduction of AdultPaederus fuscipes(Coleoptera: Staphylinidae)

Abstract

The survival and reproduction of the beetle Paederus fuscipes Curtis on diets that differed in macronutrient composition were investigated in the laboratory. The sex organs of females fed each test diet were dissected to evaluate the ovarian development over time. Adults fed on a carbohydrate-rich diet lived longer than adults fed the other diets, but this diet provided insufficient nutrients for reproduction. Females fed on a protein-rich diet had high fecundity; however, the mean longevity of reproductive adult P. fuscipes significantly was shortened by 20-30 d compared with longevity of 60-70 d for adults fed a carbohydrate-rich diet. In contrast, adults that were provided lipid-rich diet had low survival and fecundity. Overall, the development ofprevitellogenic follicles was significantly affected by diet regime and days since starting a particular diet. The follicle size of females given protein-rich diet increased 0.5-fold 2 wk after beginning the diet. In contrast, the development of the follicles was slow in females given the carbohydrate-rich diet and the follicles degenerated in females given the lipid-rich diet. In terms of ovarian maturation, females fed on a protein-rich diet contained mostly vitellogenic and chorionated follicles. In contrast, the ovarioles of females on the carbohydrate-rich diet were largely occupied with previtellogenic and vitellogenic follicles, whereas for a lipid-rich diet, the follicles remained at the previtellogenic stage throughout the experiment.

“…Another group of factors affecting the quality of developmental data is related to laboratory protocols, e.g., methods of larval measurement, conditions of insect colony maintenance, or food quality and quantity [26]. Food quality influences the survival and development of insects in nature [27]. Its effect on the development was demonstrated in several species of necrophagous flies [21,[28][29][30][31][32].…”

Flowers promote ovarian development and vitellogenin gene expression in Apolygus lucorum (Heteroptera: Miridae)

“…In a similar study, females of the butterfly Euphydryas editha fed only water produced half as many eggs as those fed a sugar water mix (Murphy et al 1983). And adult females of the rove beetle Paederus fuscipes fed a protein-rich diet laid substantially more eggs over their lifetime compared with carbohydraterich food-fed females (Bong et al 2014). In general, the availability (or lack) of nutrients during oogenesis has a large impact on the ability of an insect to successfully reproduce.…”

“…Our results also highlight a possible means of pest management in mirid. Previous researches suggest that any approach that suppresses Vg transcription may reduce pest fecundity, and RNA interference, which has been used to successfully suppress Vg expression in several species (Bong et al 2014;Lu et al 2015), may represent a novel strategy against this insect pest.…”

Amino acid quality modifies the quantitative availability of protein for reproduction inDrosophila melanogaster

“…To optimise fitness, organisms must consume a sufficient quantity and quality of nutrients to suit their needs (Hall et al, 2008, Lee et al, 2008, Bong et al, 2014). This is demonstrated by the dramatic changes in reproductive function seen when flies or rodents are subjected to food restriction or changes in diet balance, particularly when the relative proportion of protein to carbohydrates is changed (Widdowson and Cowen, 1972, Good and Tatar, 2001, Carey et al, 2002, Liang and Zhang, 2006, Lee et al, 2008, Skorupa et al, 2008, Simpson and Raubenheimer, 2012, Solon-Biet et al, 2015, Camus et al, 2019).…”
