Abstract

An outline is presented of the results, currently being analysed, of a survey of farmers' crops of pigeonpea [Cajanus cajan] in 15 Indian States. The survey, which began in 1975, involved 1112 fields. In the southern zone (below 20 deg N. lat.), 41% of the pods were damaged by lepidopterous borers (mainly Heliothis armigera (Hb.)), 13.2% by Melanagromyza obtusa (Mall.), 2.6% by Tanaostigmodes sp. (which causes much more damage to pigeonpea on research farms than in farmers' fields) and 6.3% by bruchids. In the central zone (20-23 deg N. lat.), the corresponding percentages were 25.1, 21, 1.2 and 2.4. In the northern zone (above 23 deg N. lat.), the percentages were 15.8, 22.5, 0.1 and 0.1, respectively
