Damage caused by caterpillars in chickpea crops in tropical regions.

Caterpillars in chickpea crops represent a significant challenge, as these pests can cause substantial damage to crops. Caterpillars can lead to nutritional deficiencies in plants, reduce the number and quality of grains, and in severe cases, even result in total crop failure. The aim of this study was to report the first occurrence of defoliating caterpillars in chickpea crops, cultivar BRS Cristalino, in northern Minas Gerais, describing the damage caused to the plants, aiming to fill this knowledge gap and contribute to the sustainable development of this important legume in the country. This study was conducted in an experimental area without chemical control, relying only on manual collection of caterpillars. The occurrence and damage of caterpillars during planting were evaluated. Four species of caterpillars were identified: Heliothis virescens, Helicoverpa armigera, Spodoptera eridania, Oxydia saturniata. Damage occurred in 27% of the pods and 33% of the leaves sampled. In the leaves, the caterpillars caused partial and total loss of parts of the leaves, and attacked the stem of the plant, leading to structural weakening. Attack on the pods and developing grains resulted in damaged grains, which decreased the quality of the product. These findings highlight the importance of early pest monitoring and management to avoid economic losses, as well as the need for further research on chickpea tolerance to pest damage and the development of integrated pest management strategies.
