متن کاملAdjuvants to improve aerial control of the citrus mealybug Planococcus citri (Hemiptera: Pseudococcidae) using entomopathogenic nematodes.
The citrus mealybug, Planococcus citri, is a highly destructive pest of citrus, occurring only in the aerial parts of plants. Humidity will be one of the key factors to consider when using entomopathogenic nematodes (EPN) as biological control agents. Different adjuvants can be added to suspensions of EPNs, to improve control as a foliar application. An aqueous suspension containing Heterorhabd...
متن کاملSex pheromone and analogs of the citrus mealybug, Planococcus citri: synthesis and biological activity
The citrus mealybug, is a cosmopolitan pest and affects many crops. The female sex pheromone has been identified by Bierl-Leonhardt et al., in 1981 as (+)-(1R)-cis-2,2-dimethyl-3isopropenylcyclobutanemethanol acetate 1. Several groups including our team have synthesized the pheromone. A number of analogs have also been prepared in order to study the structure-activity relationship. We present h...
