Minutaleyrodes minuta (Singh) was bred to determined the developmental duration, survivorship, longevity, fecundity and sex ratio of offspring on Cucumis sativus under artificial conditions 28± 1℃, 80~85% RH, and 13L : 11D photoperiod. Time required from egg to complete development of the female and male was 15.42 days and 14.51 days, respectively. The hatching rate of eggs was 86.8%, and survivorship of the immature stage was 66.9%. Mean total fertility and the average number of eggs laid per female of daily fertility were 106.22 eggs/female and 4.99 eggs/female/day, respectively. Females longevity was 18.03 days, and sex ratio (♀/♀+♂) of offspring was 0.79. The peak of oviposition (9.39 eggs/♀) and sex ratio of offspring (0.85) were produced by 8th day and 4th day females, respectively.

 

Key words: Minutaleyrodes minuta, development, fecundity, sex ratio.
