چکیده
|
Releases of trichogramma chilonis (ishii) (hymenoptera: trichogrammatidae), were made in farmer’s fields in shorkot, district jhang, punjab, pakistan on three sites covering eight locations for the biological control of sugarcane borers, (scirpophaga nivella f.; chilo infuscatellus snellen; emmalocera depressella swin. and acigona steniella (hampson) in 2005. perusal of data revealed that an average borer damage decreased to 43.1% at chak 496/jb, 42.3% at chak 701/43-gb and 35.1% at chak 411/jb in biological control plots in comparison to check plots. comparison of borer damage between bio-control and check fields in different sites showed effectiveness of t. chilonis to suppress the borer damage below to economic threshold level.
