In a natural situation, plants are incessantly being attacked by diverse kinds of pests and pathogens such as bacteria, fungi and insects. On the other hand naturally plants can stay alive with the help of natural enemies of these unwanted pests and pathogens. In this way, population developments of all players in a natural environment are measured. The objective of the study was to rear the Trichogramma minutum under laboratory conditions on eggs of Sitotroga cerelalla, gather their eggs on cards and then apply them on the Ornamentals against thrips. Trichogramma is a mini wasp belongs to family Trichogrammatidae which parasitized the eggs and adults of many pests, particularly eggs of moths and butterflies. Various species and strains of Trichogramma tag and destroy different host eggs and prefer different crop habitats and have distinct searching abilities and strength to weather conditions. In this study Trichogramma minutum was reared in laboratory on eggs of Angoumois grain moth (Sitotroga cerelalla) under 25-32°C temperature and 55-70% relative humidity. Key Words: Biological control, Thrips, Trichogramma minutum.
