The Uzi fly (Exorista sorbillans) is a species of bristly fly in the family Tachinidae that is a parasitoid of caterpillars and is a problem for silkworm rearing in tropical regions of South and Southeast Asia.[1]
The species found in India, Exorista bombycis is sometimes synonmyised with this species, but is distinct from specimens obtained from the type locality, the Canary Islands.[2]
Uzi flies are a friend to agriculturists and a foe to sericulturists. The life span of adult males is about 5-15 days, adult females is about 20-25 days and alternate hosts can live 55 days. Its flight range is about 4 km. It gets attracts to rearing room due to kairomone and it can locate host in 30 seconds. Its egg period is 2-3 days. Its larval period is 8 days and pupal period is about 10-14 days. It attacks all the internal organs of silkworm exept silkgland. Uzi flies lay their eggs on the silkworm caterpillar by piercing its skin.
