An investigation on “The screening of AVT lines of soybean against stem fly and girdle beetle” the field experiment was conducted at research farm, Department of Agricultural Entomology, College of Agriculture, Badnapur. During Kharif season 2017. The experiment was conducted under the Randomized Block Design (RBD) with 14 AVT lines and two replications in protected and unprotected set of conditions.

At 15 DAG the lowest seedling mortality due to stem fly was observed in check JS-335 while the highest mortality recorded in DSB-28-3 and at 30DAG the lowest seedling mortality due to stem fly was observed in JS-335 while the highest mortality was noticed in MACS-1340. At flowering lowest stem fly infestation were observed on genotype KDS-1045 and KDS-921 while the highest infestation was recorded on genotype MACS-1340 and MAUS 158. At harvesting the lowest infestation were noticed on check JS 97-52 and JS-335 while the highest infestation was observed on RSC-10-70.The lowest girdle beetle damage was recorded in check MAUS-2 while the highest damage was noticed in KDS-921.
