(Homoptera: Coccoidea) on Willow tree ( Salix Wilhelmsiana ) in Skardu, Pakistan Syed Arif Hussain Rizvi, Waqar Jaleel, Walter Maldonado Jr, Zahid Mahmood Sarwar, Saleem Jaffar and Muhammad Ayub Abstract The Drosicha sp (mealy bug) is an invasive and polyphagus pest in Baltistan, Pakistan. This pest was recorded in 2005, as primary pest of willow tree (Salix wilhelmsiana). The secondary hosts of Drosicha sp was recorded in Skardu region are apricot, apple, cherry, and mulberry. Our study was designed to find out Integrated Pest Management strategies against the Drosicha mealy bug. The Gunny bag wrappings along with mud paste was showed best cultural practice to stop the crawlers as in June only 6.0± 0.92 mealy bug was recorded per plant as compared to control (12.000± 1.03). The dispersal behavior (altitude and water availability) mainly affects the infestation of mealy bug in Skardu region. The mealy bug infestation at Chumik was statistically found maximum as compared to Halqa two and Hassan colony. The Sumnius renardi was observed as a predator of mealy bug in the field. The population dynamics of mealy bug was showed positive correlation with temperature. The temperature greatly affects the population and reproduction of mealy bug in Skardu. The maximum percent mortality was caused by Movento® 240SC (Spirotetramat +Imidacloprid) 47.13% after 72 hours of application.

About 5000 species of mealy bug recorded from all over the world from 246 families of different plants species [2] . The Drosicha sp mealy bug is one of the most devastating pests of agricultural crops. From recent decade the tendency of mealy bug invasiveness is increasing towards agricultural and horticultural crops [16] . The name mealy was given by the unique character of mealy bug female of releasing a waxy material from glandular glands of her body in which they laid her eggs. The male of mealy bug are winged while the female are wing less [5] . The mealy bug feeds on sap of plant [4] . The Drosicha sp mealy bug sucks the cell sap from succulent part of plant and produce honey dew that reduce surface area of leaves and cause reduction in photosynthesis [1] . Due to the feeding of Drosicha sp branches of Plant become weak, in some cases sever infestation may result in premature dropping of fruits [23] , ultimately death of whole plant may occur. The mealy bug secretes honey dew on which fungal growth occurs which reduce surface area for photosynthesis and plant health greatly affect. [20] . For the cultural control of mealy bug sticky bands are widely used to stop the crawlers to across the bands and the clustering mealy bugs below the bands are smashed or burn [24] . Burlap bands reduce the population of mealy bug crawlers up to 78.97% when was applied in month of February before emergence of mealy bug nymphs [9] . Several classes of synthetic insecticides were recommended for control of mealy bug including pyrethroids, carbamates, neonicotinoids, organophosphates, some (IGRs) insect growth regulators [13] . However, main reliance on insecticides results in pest resistance, resurgence, environmental hazards [21] . Because of sucking mouth part of the mealy bug and waxy cover around their body only Systemic Insecticides showed good results as compared to the contact insecticides [21, 22] . However the rapid use of synthetic insecticides results in pest resurgence and resistance [5] .
