Description Large numbers of eggs of Helicoverpa armigera were found deposited on exotic and atypical substrates in a chickpea field in Andhra Pradesh, India, in November 1992. Eggs had been laid on thin metal stakes bearing labels, weeds, stubble from a previous cereal crop, and on the chickpea crop itself. It is suggested that an exceptionally large infestation of the pest (recorded by pheromone traps in the field) may have been responsible for this behaviour. Larvae hatching from eggs laid on weeds and other substrates crawled onto chickpea plants and began feeding. It is noted that counting eggs on crop plants could therefore underestimate the pest population, and that field sanitation could play an important role in minimizing the availability of alternative oviposition sites.
