Abstract:

Survey were conducted to document the mealy bug species, alternate hosts and natural enemies complexes of mealy bug, Phenacoccus solenopsis (Psuedococcidae: Hemiptera) in cotton ecosystem of Madurai, Theni, Sivaganga, Virudhunagar and Ramnad Districts of South Tamil Nadu, India. From the frequent survey 5 species of mealy bugs identified on different cotton cultivars. Among the mealy bug species existed in cotton ecosystem P. solenopsis scored most important species in cotton. A total of 24 weed species were identified as alternate hosts for P. solenopsis. Predators such as coccinellids, Green lace wing Chrysoperla carnea, Lepidopteran Predator Spalgius apius and parasitoids of Encyrtids and unidentified Eulophid were recorded as natural enemies against P. solenopsis in cotton ecosystem of surveyed areas.
