Technical Abstract: The ladybeetle, Delphastus catalinae, is an important insect predator of the silverleaf whitefly, Bemisia argentifolii. This whitefly pest causes damage to plants through direct feeding and transmission of plant diseases. D. catalinae is a voracious predator of whiteflies in various plants such as vegetables, ornamentals, horticultural and row crops. This beetle is also mass produced by biological control companies and is popularly sold in commercial greenhouses, especially in Europe. We studied predation, development and reproduction of this predator to optimize its use in mass rearing and augmentation in field conditions.
