Abstract

ABSTRACT Natural enemies, such as insects and diseases, infesting Lonicera spp., Ribes spp. and Pueraria tuberosa (high altitude forest weeds) were investigated through out Pakistan. As a result of this 20 species of insects and a disease of Lonicera spp., 12 species of insects on Ribes spp. and 8 species of insects on P. tuberose were recorded. Among these, 6 insects (Alucita spilodesma Meyr., Psychromnes stra phaeothicta Meyr., Phyllonorycter montanella Bradley, Caloptilia delosticata Meyr., Paraphytomyza sp. and Hyadaphis sp.) and the disease caused by Lasiobotrys lonicerae Fr.) Kunze attacking Lonicera spp.;3 insects (Nematus ribesii (Scop.), Zelleria ribesiella Joanis and Anthaxia sp.) damaging Ribes sp.; and only one insect (Callosobruchus sp.) destroying seeds of P.tuberosa caused appreciable damage to their host weeds. Investigations in the biology, ecology, and nature of damage of these promising enemies were carried out.
