Insect rearing is essential to produce high quality insects for use in small- and large-scale research, outreach, and public displays, and as food for pets and hosts for biocontrol agents for invasive insect control. Creating advances in insect nutrition using multidisciplinary approaches to address any challenges are essential to advancing insect rearing research. In the following three studies I examine three different insect species to examine how statistical design can be used to optimize diets in a commonly reared lepidopteran, assess how the addition of a diet ingredient can reduce maturation age in a mass-reared dipteran, and closely examine the relationship between a hemipteran obligate blood feeder and its obligate nutritional symbiont.Advancement of insect nutrition through diet optimization is essential for improving a variety of rearing operations. Statistical approaches, such as Design of Experiments (DOE) can be utilized to test multiple ingredients and their interactions on insect fitness outcomes. In the first study, a diet was optimized to promote survival and high body mass of larval Galleria mellonella (L.), the greater wax moth. Analysis of 17 ingredient variations in 35 diet formulations using full factorial and mixture design, yielded an optimized diet that supported high survival and 2.4-fold greater larval body mass than the standard rearing diet. This study demonstrates the importance and efficiency of statistical DOE in guiding the optimization of insect diets to improve traits that are associated with the quality of reared insects.In mass-rearing for sterile insect technique (SIT), millions of sterile males are produced and released weekly to out-compete wild males and reduce invasive populations and the spread of pest populations. For fruit flies, age of male maturation and quantity of sperm transferred during mating are important for a successful SIT program. In the second study, Mexican fruit flyAnastrepha ludens (Loew), adult diets containing methoprene, and three hydrolyzed yeast diet presentation methods were tested to determine whether methoprene and hydrolyzed yeast accelerate male maturation and affect the quantity of sperm transferred to the female. Males fed a dry formulation of yeast and sugar mated 1 day sooner than males fed all other diets, but methoprene-containing diets did not affect mating age. Male maturation age and diet did not affect the quantity of sperm transferred to females. The results suggest that the yeast presentation method has significant effects on A. ludens male sexual maturation but not on the quantity of sperm transferred to females.One of the most fascinating and challenging diet development systems is developing a diet for insects that feed on nutritionally unbalanced diets such as phloem, nectar and blood. These insects often require nutritional symbionts to survive. In the third study I examined the symbiotic relationship between Wolbachia (Wb), an obligate nutritional symbiont that produces B-vitamins in bed bugs, Cimex lectularius L. Aposymbiotic bed bugs had slower nymphal development, lower adult survivorship, smaller adult size, fewer eggs per female, and lower hatch rate than bed bugs that harbored Wb.
