Abstract

The pepper weevil (Anthonomus eugenii Cano) is a serious invasive pest of peppers in Ontario. The goal of this research was to improve detection and monitoring tools for A. eugenii to minimize losses in cultivated peppers. In lab trials, fewer A. eugenii escaped from sticky cards compared to other trap types, and sticky cards coated with new adhesives formulated for A. eugenii retained the most adults. Trécé pheromone lures attracted the highest number of A. eugenii in field trials compared to other lures. The addition of kairomones did not synergize A. eugenii response to pheromone lures in lab or greenhouse trials, possibly due to experimental conditions that may have affected adult response and behaviour. Therefore, the use of kairomones in A. eugenii monitoring requires further investigation. Until then, the currently available pheromone lures and sticky cards should continue to be used for monitoring for A. eugenii in Ontario pepper crops.

Abstract

Efficacy of aphid alarm pheromone namely, trans-β-farnesene 90%, compared with conventional control methods included insecticides (Chess and Malathion in rotation) as well detergent treatment against the green peach aphid, Myzus persicae Sulz. on pepper plants was practiced in open fields at Regwa farms, Cairo-Alexandria desert road, Egypt during the summer and autumn pepper plantations, 2009. The alarm pheromone application was applied at two rates, 16 and 8ml/feddan compared with two insecticidal applications and two detergent treatments. Generally, the aphid pheromone application at both rates induced significant higher reduction means in the infestation rates of M. persicae for one month during the two plantations as compared to the other methods. The reduction rate was higher in the area treated with 16ml/ feddan of the aphid alarm pheromone than that treated with 8ml/ feddan. Based on the reduction in infestation rates, efficacy of the control methods could be descendigly arranged as; 16 and 8ml/ feddan of the pheromone, insecticides and detergent treatments. Corresponding means of reduction rates were 89.43, 87.42, 78.78 and 66.92% in summer and autumn plantations, respectively. Pheromone experimental trials showed higher attraction of the two predatory insects; Coccinella undecimpunctata L. and Chrysoperla carnea Steph., maybe due to the kairomone action than in the plots treated with insecticides and detergent as well as the untreated area.
