Aphid species, their parasitoids and predators on vegetables (bean, cucumber, eggplant, melon, okra, pepper, pumpkin, tomato watermelon) grown in Erzincan province, Turkey were determined. Surveys carried out at weekly intervals from the seedling period until end of harvest Central Üzümlü districts province 2014-2016. 30-40 plants randomly selected surveys all parts investigated with a magnifie...

Based on the importance of using low-risk compounds to protect beneficial agents, present study evaluated acute toxicity lethal and sublethal concentrations insecticides thiacloprid, pyriproxyfen, chlorantraniliprole adults Aphelinus mali (Haldeman), main parasitoid woolly apple aphid, Eriosoma lanigerum (Hausmann). Similarly, acetamiprid, buprofezin, cyantraniliprole were Acerophagus flavidulu...

Four insecticides were tested for their suitability to an integrated pest management program of woolly apple aphid (WAA). The tested insecticides were imidacloprid, pirimicarb, cartap and petroleum oil. Three indices were developed to determine the degree of selectivity of studied insecticides and to determine their suitability to WAA IPM program. WAA index used to measure the efficacy of the i...

1. Parasitoid acceptance of host individuals that differ in suitability is dynamic, varying with physiological state and experience. Female parasitoids with high egg loads and low life expectancy (i.e. time limited) are more willing to accept hosts with low suitability for progeny development than females with low egg loads and high life expectancy (i.e. egg limited). However, studies of dynami...
