Abstract

Experiments on biology of spiralling whitefly (Aleurodicus dispersus) was conducted in the laboratory of Department of Agril. Entomology, PGI MPKV Rahuri in 2022. Spiralling whitefly completed life cycle within 42.4 to 46.6 days, with an average of 47.7 days. The average duration of first, second, third and fourth instars were 6.6, 5.1, 6.0 and 6.8 days, respectively. The incubation period lasted for 6.7 days with 96 percent egg hatching. The sex ratio for male to female was 1:1.43. Female laid on an average 43.8 eggs on adaxial surface of the leaves in loose spiral pattern covered with wax
