Development and reproduction of mole crickets (Orthoptera: Gryllotalpidae) after treatments with hydropene and pyriproxyfen
Journal of Economic Entomology 91 (2), 392-397
Abstract: Hydroprene and pyriproxyfen, as liquid sprays applied to soil and as bait formulations, were evaluated against nymphs of Scapteriscus abbreviatus Scudder in the laboratory. Small and large nymphs were treated. Survival, development, and resulting progeny production were observed. Hydroprene treatments affected neither survival and development of nymphs nor reproduction of resulting adults. Pyriproxyfen treatments causing substantial mortality were the 0.5% spray to small nymphs (33% mortality), 0.1% spray to large nymphs (33% mortality of females), 0.5% spray to large nymphs (87 and 67% mortality of females and males, respectively), and baits offered to large nymphs (40% mortality of females) . Concentrations of pyriproxyfen within each treatment group that caused the most deformities of surviving adults were the 0.1% spray to small nymphs (85% of females and males deformed), 0.5% spray to large nymphs (100% of males deformed), and the 0.5% bait offered to large nymphs (46% of females deformed). Baits offered to small nymphs caused no deformities. Nymphal development times were significantly lengthened by most pyriproxyfen treatments. Treatments significantly reducing progeny (egg and nymph) production of surviving adults were 0.1 and 0.5% sprays to small nymphs and 0.02, 0.1, and 0.5% sprays to large nymphs. Progeny production was significantly reduced when one or both members of a mating pair were deformed. The potential of pyriproxyfen for mole cricket control and possible limitations are discussed.
