Plutella xylostella • Delta traps • Funnel traps MASS TRAPPING Mass trapping is a method to reduce populations and control the pest. This work evaluated the effects of a cladode extract from Opuntia ficus-indica (CE) on the survival and development of P. xylostella, as well as on its oviposition behavior. If no sprays were applied for control of P. xylostella, the crop losses of the summer crop of cabbage in Jiangsu were 99% in 1992 and 80% in 1994, compared with the plots treated by insecticides (21-23 tons/ha.) Diamondback Moth Plutella xylostella. In the present study, two full length cDNA encoding cecropin2 (Px-cec2) and cecropin3 (Px-cec3) were obtained from P.xylostella by integrated analysis of genome and transcriptome data. It was the first crop insect reported to be resistant to DDT and now, in many crucifer producing regions, it has shown significant resistance to almost every synthetic insecticide applied in the field. The search for new compounds to control Plutella xylostella, the main pest of Brassica crops, has been stimulated by the environmental impact of the insecticides currently used and reports of resistant populations. pp. Abstract. Cecropins are the most potent induced peptides to resist invading microorganisms. This pest is notorious for rapid evolution of the resistance to different classes of insecticides, making it increasingly difficult to control.
