D3020: The effect of juvenile hormone analogues (Juvenoids) in Turkestan cockroaches (Periplaneta lateralis)

The Turkestan cockroach (Periplaneta lateralis) is an invasive pest in the United States, originating from Central Asia. Its ability to adapt to dry environments and its high reproductive potential have made this species very common in urban areas in the Southwestern US. While perimeter treatments with traditional synthetic insecticides (such as pyrethroids, neonicotinoids, or chlorfenapyr) are commonly used for Turkestan cockroach control, there are promising alternative chemicals with lower environmental impacts, such as insect growth regulators (IGRs). In this study, we evaluate the effects of Juvenile Hormone analogues (S-hydroprene, Precor S-methoprene, and pyriproxifen), as well as the chitin synthesis inhibitor Novaluron, on various life stages of Turkestan cockroaches. Early and late instar nymphs, as well as adult females, will be exposed to IGRs in a harborage-seeking bioassay, which include an insecticide-treated platform. Reproductive parameters, such as ootheca production and hatching, as well as abnormalities in reproductive structures of females and males, will be evaluated. Similarly, mortality and molting abnormalities will be assessed in IGR-exposed nymphs. The use of IGRs could be an alternative tool to be included in Integrated Pest Management strategies for Turkestan cockroaches in areas where they are abundant.
