Abstract

The objective of this work was to briefly describe each of the developmental stages of Paraphytoseius orientalis (Narayanan et al.) and to determine its life history parameters and prey consumption on the Broad Mite, Polyphagotarsonemus latus (Banks). The incubation period of the eggs was 1.5±0.6 days for the male and 1.5±.4 for the female. The development time (in days) of the other stages for males and females were respectively as follows: larva 1.6±0.8 and 1.3±0.4; protonymph, 1.1±0.2 and 1.1±0.3; deutonymphs, 1.0±0.0 for both. Toral development time (egg to adult) was 5.6±0.2 for male and 6.3±0.6 for female. Durations of post-development periods of mated female were as follows: pre-oviposition, 3.6±3.3; oviposition, 13.3±5.6 and post-oviposition, 3.4±3.0. Longevity of unmated females (21.5±10.6) was slightly longer than that of mated ones (20.5±5.7). Unmated females did not lay eggs, while mated females laid 13±9 eggs. Adult female P. orientalis consumed the greatest number of prey eggs at the highest prey density offered, an important characteristics of a potential biological control agent against the Broad Mite.
