ABUNDANCE OF THE MYZUS PERSICAE (SULZER) UNDER PROTECTED ENVIRONMENT IN HIMACHAL PRADESH, INDIA
Myzus persicae (Sulzer) (Hemiptera: Aphididae) is an economically important pest with over 500 host plants in many parts of the world. At the same time, it is also an important pest of many vegetable crops, including bell pepper grown under protected environment in India. There is very scarce information available regarding this pest in India. Therefore, survey was conducted in the polyhouses at different periods during the crop season and observations were recorded on the incidence in polyhouse. Per cent incidence of M. persicae was recorded on different varieties of C. annuum in polyhouses at different locations in each of the four districts of Himachal Pradesh viz. Bilaspur, Hamirpur, Kangra and Mandi. The aphid was observed to infest the crop at seedling, flowering and fruiting stages at all the locations. Its per cent incidence, recorded at different stages of the crop, varied from 19.25 to 68.95, 42.25 to 73.25, 37.58 to 74.85 and 30.56 to 88.54 per cent in Bilaspur, Hamirpur, Kangra and Mandi districts, respectively. These results of the survey show that M. persicae is a very serious pest of the crop transplanted at different times under protected environment at different locations in Himachal Pradesh.
