Abstract :
Present study was carried out to determine the numbers of egg batches and eggs per batch in the maize fields of selected sites of Indore. Moreover, discovery efficiency and parasitism efficiency was also determined. The result revealed that highest mean discovery efficiency rates of Trichogramma spp. was found from Mhow and was therefore having low parasitism per field and lowest mean discovery efficiency rate was recorded from Mangliya and was having high parasitism per field. There was generally a high variation in the numbers of egg batches and eggs per batch among the sites surveyed. The predominant parasitoid species was Trichogramma spp. This study showed that although egg parasitoid species diversity was higher, egg parasitism was considerably lower in selected sites of Indore.

Key-Words / Index Term :
Trichogramma spp, discovery efficiency, egg parasitism. parasitism efficiency
