Abstract
Insect pests are the major constraints for pigeonpea yield reduction. Large-
scale integrated pest management (IPM) of pigeonpea was undertaken on
1000 ha in Parbhani in farmers’ participatory mode. The pest population
was less in IPM fields than non-IPM fields. The population of pod borer
larvae was 0.39/plant in IPM, and 0.64/plant in non-IPM. Plume moth
larvae were 0.16 and 0.25/plant in IPM and non-IPM fields, respectively.
The webbings by spotted pod borer ( Maruca vitrata Gey.) were 0.08 and
0.19/plant in IPM and non-IPM fields, respectively. The pod damage due
to pod borer complex was less in IPM (7.71 %) than non-IPM (21.52 %)
fields. The immature stages (maggot and pupa) of pod fly were 2.14 and
7.99/50 pods in IPM and non-IPM fields, respectively. The population
of natural enemies like coccinellids (0.21/plant in IPM and 0.09/plant
in non-IPM), chrysopids (0.03/plant in IPM and 0.01/plant in non-IPM)
and spider (0.36/plant in IPM and 0.24/plant in non-IPM) was more in
IPM fields. The parasitisation of pod borer larvae was 3.63 % in IPM and
1.78 % in non-IPM. The impact of the IPM practices resulted in increased
yield (10.18 q/ha in IPM and 8.41 q/ha in non-IPM) with a net profit of
₹ 7710/ha. IPM module insect pests effectively managed and conserved
natural enemies.
