evaluation of efficacy of 18 strains of entomopathogenic nematodes (rhabditida) against planococcus citri (risso, 1813) (hemiptera: pseudococcidae) under laboratory conditions.planococcus citri (risso, 1813) (hemiptera: pseudococcidae) is an important plant virus vector in grapevine crops in brazil and other countries. the mealybug grows in roots and leaves of the grapes. entomopathogenic nematodes (epns) are efficient control agents against insects associated to the soil and could be applied with the same equipment used for chemical insecticides. the aim of this study was to select effective epns for controlling p. citri females in laboratory conditions (25±1°c, ur 6 ...201323458234
control of grapholita molesta (busck, 1916) (lepidoptera: tortricidae) with entomopathogenic nematodes (rhabditida: heterorhabditidae, steinernematidae) in peach orchards.oriental fruit moth grapholita molesta (busck, 1916) (lepidoptera: tortricidae) is considered a major pest in temperate fruit trees, such as peach and apple. entomopathogenic nematodes (epns) are regarded as viable for pest management control due to their efficiency against tortricid in these trees. the objective of this study was to evaluate the effectiveness of native epns from rio grande do sul state against pre-pupae of g. molesta under laboratory and field conditions. in the laboratory, pre ...201323994482
