The intensive increase in poultry production requires a variety of different measures to maintain high productivity of broiler chickens while maintaining a high level of bird welfare. One issue is the growing population of Alphitobius diaperinus, which occurs all over the world. This beetle is considered a pest in poultry production and causes major losses to poultry producers. Its development cycle consists of four stages: an egg, a larva, a pupa and an adult. It is necessary to reduce the number of these insects in poultry houses, in which they constitute a serious problem both for the birds and for the buildings themselves. The beetle does a lot of damage by tunnelling in floor and wall crevices, thus destroying the insulation of the building. It has been proved experimentally that the lesser mealworm is also a vector for many serious diseases of poultry and humans. The beetle infected with pathogens may remain infectious for a long time. A. diaperinus is a carrier of dangerous pathogens and viruses as well as protozoa and parasites in poultry. The lesser mealworm shows a noticeable sexual dimorphism. Correct and quick identification of the sex of A. diaperinus on poultry farms could facilitate insect control. Field and laboratory research is being conducted to find an effective method of reducing the population of the lesser mealworm.

The Mean

The facilities used to raise broiler chickens are often infested with litter beetles (lesser mealworm, Alphitobius diaperinus). These beetles have been studied for their carriage of pathogenic microbes; however, a more comprehensive microbiome study on these arthropods is lacking. This study investigated their microbial community in a longitudinal study throughout 2.5 years of poultry production and after the spent litter, containing the mealworms, was piled in pastureland for use as fertilizer. The mean most abundant phyla harbored by the beetles in house were the Proteobacteria (39.8%), then Firmicutes (30.8%), Actinobacteria (21.1%), Tenericutes (5.1%), and Bacteroidetes (1.6%). The community showed a modest decrease in Firmicutes and increase in Proteobacteria over successive flock rotations. The beetles were relocated within the spent litter to pastureland, where they were found at least 19 weeks later. Over time in the pastureland, their microbial profile underwent a large decrease in the percent of Firmicutes (20.5%). The lesser mealworm showed an ability to survive long-term in the open environment within the spent litter, where their microbiome should be further assessed to both reduce the risk of transferring harmful bacteria, as well as to enhance their contribution when the litter is used as a fertilizer.

An unavoidable by-product of any animal production system, be it vertebrate- or invertebrate-based, is the manure generated by the animals themselves. In this review, we focus on the role that insects, particularly the black soldier fly Hermetia illucens (L.) (Diptera: Stratiomyidae), could play in managing the mass amount of manure produced through animal agriculture, and the subsequent commodities that could be generated by such a system. Although the focus of this review is on the black soldier fly, we postulate that other species, including the lesser mealworm Alphitobius diaperinus (Panzer) (Coleoptera: Tenebrionidae) and the house fly Musca domestica L. (Diptera: Muscidae) are also well poised to help with the challenge of managing animal manure, while generating products of value.

Objetivou-se selecionar isolados nativos de nematoides entomopatogênicos (NEPs) e avaliar o efeito da cama de aviário na sua patogenicidade e virulência, visando o controle do cascudinho de aviário. Foram utilizados 18 isolados (Steinernema e Heterorhabditis) no teste de seleção e os três isolados mais virulentos foram utilizados no teste de concentrações (10, 20, 40, 50 juvenis infectantes (JIs)/cm²). O efeito da cama de aviário (nova e velha) foi avaliado sobre S. feltiae (IBCB-n 47), S. carpocapse (IBCB-n 02), H. bacteriophora e H. amazonensis (UEL 08). Os experimentos foram realizados em delineamento inteiramente casualizado. Os dados do teste de seleção e efeito da cama foram submetidos ao teste de médias Scott-Knott (P?0,05) e, do teste de concentrações à análise de regressão. Observou-se no teste de seleção para adultos, que os três isolados mais virulentos foram Heterorhabditis amazonensis (UEL 07), H. amazonensis (RSC 05) e Steinernema carpocapsae (IBCB-n 02) com 76,5; 73,5; 70% mortalidade respectivamente. Para larvas, Heterorhabditis sp. (NEPETT 11), S. feltiae (IBCB-n 47), H. amazonensis. (UEL 07) foram os mais virulentos e causaram 100; 96; 93,7% de mortalidade respectivamente. No teste de concentrações, a maior mortalidade em adultos (98%) e larvas (98%) foi observada para S. feltiae nas concentrações de 30 JIs/cm² e 50JIs/cm² respectivamente. Com relação ao efeito da cama de aviário, observou-se que S. feltiae (IBCB-n 47) e S. carpocapse (IBCB-n 02) causaram as maiores mortalidade tanto em cama nova (60,7 e 58,7%) quanto em cama velha (80 e 74,7%) respectivamente.
