Abstract:
... Vine weevil, Otiorhynchus sulcatus F. (Coleoptera: Curculionidae), is an economically important insect pest of horticultural crops. To identify an effective and reliable monitoring system for adult vine weevil, this study investigated the influence of colour, height and entrance position on the efficacy of a model monitoring tool using modified paper cups as refuges. Vine weevil preferences were d ...

Abstract:
... To develop a new pest control device for greenhouses, we verified the effect of the noncontact force generated by ultrasonic transducers on two small insect pests: the sweet potato whitefly Bemisia tabaci Gennadius and the cotton aphid Aphis gossypii Glover. First, we examined their dispersion behavior in response to the device, and the dispersion rate of whiteflies from leaves was approximately 6 ...

Characteristics related to its life cycle makes it very difficult to control. Usually, CBB control measures are carried out at plot scale, with almost no actions taken at wider landscape scales. It is unclear how plot ...

Abstract:
... Greenbug (Schizaphis graminum Rondani) is a destructive insect pest that not only damages plants, but also serves as a vector for many viruses. Host plant resistance is the preferred strategy for managing greenbug. Two greenbug resistance genes, Rsg1 and Rsg2, have been reported in barley. To breed cultivars with effective resistance against various greenbug biotypes, additional resistance genes a ...
