Abstract: The Uzi fly, Exorista sorbillans (Wiedemann) is a major pest of the mulberry silkworm, Bombyx mori L. in Andhra Pradesh leading to great cocoon crop loss. It is considered that acquisition of knowledge on the infestation of uzi fly on silkworm in Rayalaseema districts of Andhra Pradesh form an important basic input for drawing silkworm cocoon crop protection strategies. Keeping the above in view, a survey was conducted to know the infestation levels of uzi fly on mulberry silkworm in three important sericulture practicing districts of Rayalaseema i.e., Anantapur, Chittoor and Kurnool of Andhra Pradesh, India during three seasons (summer, rainy and winter). Results revealed that the infestation of uzi fly on commercial mulberry silkworm cocoon crop was high during rainy season (14.73 ± 5.27%) followed by that during winter (8.62 ± 4.16%) and summer (4.77 ± 4.68%). Identical trends in uzi infestation among three sericultural districts (Anantapur, Chittoor and Kurnool) were observed during three seasons studied (summer, rainy and winter). Average uzi incidence was high in Anantapur District (10.01 ± 4.56%) followed by that in Chittoor District (5.84 ± 2.20%) and Kurnool District (4.77 ± 4.68%). Average uzi fly incidence on the commercial silkworm cocoon was 9.37 ± 4.23%. Differences in uzi fly infestations among three districts surveyed and average incidence are statistically highly significant at 1% level (p< 0.01).
