Knockdown, Residual, and Antifeedant Activity of Pyrethroids and Home Landscape Bioinsecticides Against Japanese Beetles (Coleoptera: Scarabaeidae) on Linden Foliage

Antifeedant effect of commercial chemicals and plant extracts againstSchistocerca americana(Orthoptera: Acrididae) andDiaprepes abbreviatus(Coleoptera: Curculionidae)

“…Potato plots treated with a capsaicin extract did not decrease the incidence of the Colorado potato beetle, L. decemlineata 53. Baumler and Potter54 also reported the inefficacy of capsaicin in reducing defoliation of linden ( Tilia cordata L.) by the Japanese beetle.…”

Long Chain Alcohols Produced by Trichoderma citrinoviride Have Phagodeterrent Activity against the Bird Cherry-Oat Aphid Rhopalosiphum padi

“…Their phagodeterrence is due to the presence of pyrethrum and azadirachtin A, respectively. Pyrethrum and its analogs pyrethrins are widely used as insecticides in agricultural, public health, and domestic applications (Wesseling et al, 2001 ; Ray and Fry, 2006 ) and have also a repellent effect toward different species of insects (Baumler and Potter, 2007 ; Patel et al, 2012 ; Prota et al, 2014 ). Azadirachtin blocks the synthesis and release of molting hormones from the prothoracic gland, leading to incomplete ecdysis in immature insects and to sterility in adult females and is a potent antifeedant compound to many insects species (Isman, 2006 ; Gahukar, 2014 ).…”

Japanese Beetle and Other Coleoptera Feeding on Grapevines in Eastern North America

“…Phosmet is one of the few organophosphates currently registered for vineyards in the United States (Wise et al 2009 ) , and is highly active on JB. Pyrethroids have been reported to be more effective than carbaryl (Baumler and Potter 2007 ) . However, they are even more toxic to predators and parasitoids, and have been linked with outbreaks of grape mealybug in vineyards, a vector of grapevine leafroll virus.…”
