Nutrient abundance during development has profound effects on adult morphology, life history and behaviour in many insects, but effects of nutrition on juvenile development are less well known. We investigated how larval diet quality affects patterns of growth, development and survival of larvae and pupae in the neriid fly Telostylinus angusticollis (Enderlein). We reared flies on two larval diets varying in nutrient concentration (‘rich’ versus ‘poor’) that have been shown previously to affect a wide range of adult traits in this species. We found that nutrient concentration affected larval growth trajectories, with individuals reared on the rich diet exhibiting greatly accelerated growth and reaching a larger body size. By contrast, we found no evidence that diet affected timing of development at the pupal stage, suggesting that developmental constraints may prevent variation in pupal development rate. Although overall mortality during the immature stages was not affected by larval diet, we found some evidence that individuals reared on a poor diet might experience higher larval mortality, whereas individuals reared on a rich diet might experience higher mortality during emergence from the puparium. Our results enhance understanding of the effects of nutrition on growth, development, and life history.

Growth And Survival

Optimising the production of insects for food and feed and ensuring their health are growing concerns for producers. Insects suffer from a range of insect pathogenic microorganisms, and the management of such diseases is essential. One solution is the introduction of beneficial probiotic bacteria into the diet of the insects. Here, we show that a lactic acid bacterial strain, Pediococcus pentosaceus, isolated from the gut of the mealworm, Tenebrio molitor, was able to inhibit the growth of selected insect pathogens in vitro. Using in vivo assessments of the host’s fitness benefits conferred by the lactic bacterium we show a significant effect of P. pentosaceus on larval growth rate and survival into adulthood. Gut microbiota analysis focusing on bacterial composition based on 16S rRNA gene amplicon sequencing suggests that P. pentosaceus could have successfully colonised the guts, or altered their bacteria, of the larvae that received it. Finally, we discuss our results in the context of mass insect production systems and outline the remaining work needed to explore and secure the role of beneficial bacterial additives in the field.

Yellow mealworm is a grain infesting pest that is receiving attention nowadays as an alternative protein source for humans and animals. Its ability to convert low quality feed, like organic by-products, into high-quality food increases its production sustainability. The feeding diet is one of the most important factors in rearing Tenebrio molitor Linnaeus (Coleoptera: Tenebrionidae), which affects its growth, longevity and nutritional composition. Many by-products have been tested on larvae, but studies are scarce on adults. This work aimed to compare the effect of chicken feed diet (C) and wheat bran (B) by-product, as well as integrating yeast (CY and BY), on the adults’ reproduction and larval growth. Experiment was set up in a complete productive cycle of mass-rearing. The evaluation was done on the reproductive stage of the adults and the development of the larvae until harvesting (appearance of the first pupa). Results showed that the bran-based diets significantly improved the adults’ survival; after 50 days, mean of 110 and 146 adults survived on B and BY diets respectively compared to mean of 23 adults when reared on both chicken feed diets. Besides, wheat bran supplemented with yeast improved the total number of larvae (6,448.2 larvae) compared to bran diet (4,016.7 larvae). Whereas the two chicken feed-based diets had significant positive effect on the average larval weight; the maximum weight reached was 116.3 mg and 145.8 mg for larvae read on C and CY diets respectively compared to 47.8 mg and 57.3 mg on B and BY diets. Nevertheless, in 50 days of reproduction, the total larval biomass was highest on bran supplemented with yeast (283.1 g). In conclusion, the increase of sustainability and efficiency in mass-rearing of mealworms is possible by using appropriate diets on respective stages; bran-based diets for reproduction and chicken feed-based diets for larval growth.
