Title: Novaluron: Prospects and Limitations in Insect Pest Management
Author: Cutler, G. Christopher; Scott-Dupree, Cynthia D.
Abstract: Biorational insecticides are a valuable insect pest management option for growers and pest management practitioners. Novaluron is a recently developed benzoylphenyl urea insecticide with excellent activity against several important insect pests. Through inhibition of chitin synthesis, larval insect stages are targeted with death from abnormal endocuticular deposition and abortive molting. This physiological specificity lends novaluron well to integrated pest management (IPM)programs, as toxicity to mammals, birds and other vertebrates is low, and adult beneficial insects, including predators, parasitoids and pollinators, are generally unaffected. Foliar applications have demonstrated prolonged persistence, providing long-lasting control for growers, and the mode of action of novaluron, completely different from that of commonly used neurotoxic insecticides, makes it a useful alternative insecticide for resistance management. However, there are several obstacles, many inherent to IPM, which may hinder the utility of novaluron. While its narrow spectrum of activity is a key attribute, paradoxically this may be a significant detractor for growers who prefer broad-spectrum control of multiple pests. As an insect growth regulator, timing of novaluron applications is often more restrictive and delayed insecticidal activity usually occurs. The purchase price of benzoylphenyl ureas is generally greater than that of conventional insecticides, which may limit the appeal of novaluron. Further, studies have shown that some beneficial organisms are susceptible to novaluron. Knowledge reviewed here will facilitate continued development and use of biorational compounds for IPM.
