The thermotolerance of the emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), was evaluated by subjecting larvae and prepupae to a number of time-temperature regimes. Three independent experiments were conducted during 2006 and 2007 by heating emerald ash borer infested firewood in laboratory ovens. Heat treatments were established based on the internal wood temperature...

Effective survey methods to detect and monitor recently established, low-density infestations of emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), remain a high priority because they provide land managers and property owners with time to implement tactics to slow emerald ash borer population growth and the progression of ash mortality. We evaluated options for using gi...

The biological control agent Tetrastichus planipennisi Yang (Hymenoptera: Eulophidae) is a gregarious larval endoparasitoid of the emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), an invasive cambium-feeding species responsible for recent, widespread mortality of ash (Fraxinus spp.) in North America. T. planipennisi is known to prefer late-instar emerald ash borer, bu...

Mating disruption and mass trapping for control of lepidopteran pests use synthetic sex pheromone to prevent males from finding and mating with females. Here, we identify the behavioral mechanism underlying mating disruption and mass trapping of American plum borer, Euzophera semifuneralis (Walker) (Lepidoptera: Pyralidae), peachtree borer, Synanthedon exitiosa Say, and lesser peachtree borer, ...

in order to evaluate the efficiency of biocontrol agents of corn stem borer ,ostrinia nubilalis, experiment was conducted in a randomized complete block by five treatments and four replication, including, indoxacarb (avant)®, trichogrammawasps, bacillus thuringiensis var: kurstaki, integration of trichogramma sp. and bt., and control as treatments number 1 to 5. in treatments with parasitoid re...

Melaleuca leucadendra and M. cajuputi are grown widely in Vietnam, with plantation areas 2020 of 32,000 ha 36,000 respectively. A stem borer, Neurozerra conferta (Walker) (Lepidoptera: Cossidae), has significantly damaged plantations both species. Field surveys 2021 found N. damage to the four provinces Ninh Binh, Long An, Dong Thap Kien Giang a incidence (P%, percentage plants attacked) 22.4–3...
