Survivorship, larval development and pupal weight of Anticarsia gemmatalis (Hübner) (Lepidoptera: Noctuidae) feeding on potential leguminous host plants
Neotropical Entomology 33 (5), 563-567
Abstract: In Brazil, the velvetbean caterpillar Anticarsia gemmatalis Hübner is multivoltine. Several overlapping generations occur with larvae feeding on alternate host plants in areas of warmer temperatures. In this study, the survivorship and development of A. gemmatalis larvae were evaluated on 17 species of cultivated and non-cultivated legumes in laboratory conditions. Larval survivorship on summer legumes varied from 91% on soybean to 5% on showy crotalaria and on velvetbean. On winter legumes, survivorship of A. gemmatalis larvae varied from 90% on white lupin to 25% on common vetch. All larvae fed on yellow lupin died during early development. On non-cultivated summer legumes, 70% of the larvae on Indigofera suffruticosa Millsp., and 55% on I. truxillensis H.B.K. and I. endecaphylla Jacq. reached the pupal stage. Based on survivorship, larval development and pupal weight, the most suitable legumes for A. gemmatalis were soybean, pigeon pea, and white lupin.

No Brasil, a lagarta-da-soja Anticarsia gemmatalis Hübner apresenta várias gerações sobrepostas por ano e parte da população sobrevive em plantas hospedeiras alternativas, principalmente nas regiões mais quentes. O objetivo deste estudo foi avaliar o desenvolvimento e a sobrevivência de lagartas de A. gemmatalis em 17 leguminosas cultivadas e não-cultivadas, em laboratório. A sobrevivência das lagartas de A. gemmatalis alimentadas com leguminosas de verão variou de 91% em soja a 5% em C. spectabilis Roth e mucuna. Nas leguminosas de inverno, a sobrevivência das lagartas variou de 90% em tremoço branco a 25% em ervilhaca comum. Todas as lagartas alimentadas com tremoço amarelo morreram nos primeiros ínstares. Nas leguminosas de verão não-cultivadas (anileiras), 70% das larvas atingiram a fase pupal em Indigofera suffruticosa Millsp., e 55% em I. truxillensis H.B.K e I. endecaphyla Jacq. Considerando-se a sobrevivência, o desenvolvimento das fases imaturas e o peso pupal, as leguminosas mais adequadas para A. gemmatalis foram soja, guandu e tremoço branco.
