Abstract

Comparative development, progeny production and sex ratio of the exotic parasitoid Leptomastix dactylopii Howard (Hym., Encyrtidae) on Planococcus lilacinus and P. citri (Homop., Pseudococcidae).

Abstract

The solitary encyrtid Brazilian parasitoid Leptomastix dactylopii was able to complete its development in 3 nymphal stages and adult females of Planococcus lilacinus and P. citri. Parasitoid development was faster, the number of parasitoids emerging was greater and the ratio of females to males emerging was greater in the later stages of the host. L. dactylopii could be easily cultured on 15- to 25-day-old P. lilacinus. P. lilacinus in the absence of P. citri could be recommended for the mass breeding of L. dactylopii since the number of parasitoids emerged and percentage female progeny obtained with P. lilacinus and P. citri as hosts were very similar.
