Effects of Lead Acetate on Light Protein of Drosophila melanoigaster

Abstract

In a two-year study ten commercial date palm varieties were evaluated. The varieties showed varying response to Rhynchophorus ferrugineus Oliv; some varieties suffered heavy infestation while others indicated tolerance against R. ferrugineus. The most tolerant varieties with less infestation percentage against R. ferrugineus were Muzawati (8%) followed by Pathri (12%), Thothar (15%), Khar and Shakri (16%) respectively. The varieties which suffered high infestation rate were Karbalain, Dhedhi, Fasli, Aseel and Eidan Shah. To control the R. ferrugineus infestation pheromone trapping system was used. Significantly more R. ferrugineus (18-21) adults were captured during the 1 st , 2 nd , 3 rd week of July and 2 nd week of June. The studies conducted will be helpful in survey and control of R. ferrugineus infestation in Khairpur District of Sindh province.
