Abstract :
A lab trial was conducted during 2012–13 at Department of Entomology, College of Agriculture, JAU, Junagadh to study the bionomics of rose thrips, Frankliniella occidentalis Pergande. Laboratory studies revealed that the female laid their eggs in the leaf tissues by sharp ovipositor. The average incubation period was found 5.28 day. The larva passed through two distinct instar and average duration of each instar was 1.72 and 4.76 day, respectively. The total larval period was on an average of 6.48 day with the total pupal period of 3.96 day. The average pre–oviposition, oviposition and post–oviposition period were 3.12, 32.68 and 4.20 day, respectively. The number of progenies produced by a single female varied from 28 to 69 with an average of 58.8. The average longevity of male and female was 21.60 and 42.36 day with entire life span of 25.52 and 48.40 day, respectively. The sex ratio of male to female was worked out as 1:1.73 at a constant temperature of 25 ± 1°C.
