| Dominant predator of Tetranychus sp. were Stethorus siphonulus Kapur and Stethorus pauperculus (Weise) while Stethorus indira Kapur was dominant predator of Eutetranychus africanus Tucker. The Stethorus spp. 3 species had characteristic different in egg to pupa stages but similary at adult stages. S. siphonulus had the largest size, followed by S. indira and S. pauperculus. The development period from egg to adult stage of S. pauperculus, S. siphonulus and S. indira was 16.35 days, 12.60 days, and 14.75 days, respectively. Preference test of the predatory beetles on egg of three spider mite species showed that S. siphonulus destroy eggs of Mulberry red mite, Tetranychus truncatus Ehara, S. pauperculus destroy eggs of Two spot spider mite, Tetranychus... |
