Description Host-plant resistance to insects, in general, is controlled by quantitative traits, and as a
result, the progress in developing high-yielding insect-resistant cultivars has been quite
slow. With the advent of recombinant DNA technology, it has become possible to clone
and insert genes into crop plants to confer resistance to insect pests. Insecticidal genes from
the bacterium, Bacillus thuringiensis (Bt), which are mainly effective against the
lepidopteran insects, have been inserted into several grain legumes such as - chickpea,
pigeonpea, cowpea, soybean, groundnut, faba bean, lentil, field pea, greengram, and
blackgram. However, there is a need to discover and deploy genes that are effective against
the hemipterans and dipterans that are important pests of grain legumes. Although insect-
resistant transgenic plants have been developed in several grain legumes, these have not
been deployed for pest management because of the concerns raised about food safety and
their possible effects on the non-target organisms. To ensure a sustainable deployment of
transgenic insect-resistant grain legumes, it is important that they are compatible with other
control methods, including the biological control agents that are important for natural
regulation of pest populations. Toxin genes from Bt and non-Bt proteins are considered to
be environmentally benign and their use will reduce the hazards associated with the use of
synthetic insecticides. However, it is important to follow the bio-safety regulations, and
assure the general public about the biosafety of food derived from transgenic grain legumes,
and their biosafety to the non-target organisms in the environment for sustainable crop
production.
