Resistance to Dieldrin and Tolerance to Chlorpyrifos and Bendiocarb in a Northern New Jersey Population of Japanese Beetle1

Preharvest Quarantine Treatments of Chlorantraniliprole, Clothianidin, and Imidacloprid-Based Insecticides for Control of Japanese Beetle (Coleoptera: Scarabaeidae) and Other Scarab Larvae in the Root Zone of Field-Grown Nursery Trees

“…If efÞcacy issues can be resolved, Acelepryn could provide an alternative mode of action (i.e., group 28 ryanodine receptor modulator) ( Insecticide Resistance Action Committee [IRAC] 2012) to reduce the risk of insecticide resistance in Japanese beetle populations. Japanese beetle insecticide resistance has occurred in the past with usage of long residual insecticides (Niemczyk 1975, Lawrence et al 1977, Ng and Ahmad 1979. Insecticide products with multiple modes of action would also provide more options to nursery producers in the event of regulatory removal of any of these insecticides.…”

Surface‐applied insecticide treatments for quarantine control of Japanese beetle, Popillia japonica Newman (Coleoptera: Scarabaeidae), larvae in field‐grown nursery plants

“…All of the neonicotinoid insecticides are systemic in plants and function as acetylcholine agonists,21 while the active ingredient of Mach 2, halofenozide, is a bisacylhydrazine ecdysteroid agonist 22. The difference could aid in resistance management, since evidence for P. japonica resistance has been demonstrated in other insecticides 14, 15…”

“…Because few insecticide active ingredients (i.e. chlorpyrifos and imidacloprid) are approved for quarantine management of P. japonica grubs, and there are examples of P. japonica resistance to other insecticides,14, 15 finding alternative insecticides may help to avoid selection for insecticide resistance. In addition, availability of other options may reduce treatment costs.…”

Use of Radiography in Behavioral Studies of Turfgrass-Infesting Scarab Grub Species (Coleoptera: Scarabaeidae)

“…Less consistent control has been achieved with the many organophosphate and carbamate insecticides that replaced them (Baker 1986). Several factors, including soil pH, organic matter content, moisture, timing of application, thatch, and microbial degradation of insecticides, influence the efficacy of currently registered insecticides (Harris 1972 JB resistance to organophosphate insecticides also has been documented (Ng & Ahmad 1979, Ahmad & Ng 1981). An additional factor that current research points to as being critically important is the ability of the soil insecticide to reach the target insect species (Niemczyk 1987).…”
