Intercropping is one of the important cultural practices in pest management and is based on the
principle of reducing insect pests by increasing the diversity of an ecosystem. On–farm
experiments were conducted in villages of semi–arid tropical (SAT) India to identify the
appropriate combination of castor (Ricinus communis L.) (Malpighiales: Euphorbiaceae) and
intercropping in relation to pest incidence. The diversity created by introducing cluster bean,
cowpea, black gram, or groundnut as intercrops in castor (1:2 ratio proportions) resulted in
reduction of incidence of insect pests, namely semilooper (Achaea janata L.), leaf hopper
(Empoasca flavescens Fabricius), and shoot and capsule borer (Conogethes punctiferalis
Guenee). A buildup of natural enemies (Microplitis, coccinellids, and spiders) of the major pests
of castor was also observed in these intercropping systems and resulted in the reduction of insect
pests. Further, these systems were more efficient agronomically and economically, and were thus
more profitable than a castor monocrop.
