Resumo: | The effects of leaf surface reduction on the vegetative grown and grain yield in common bean was evaluated in an experiment carried out at Goiânia, Goiás, Brazil. Levels of 25%, 50% and 75% leaf surface reduction in 10, 17, 24, 31 and 38-days-old plants were tested. A second experiment was conduced using 0.3 x 0.7 m cages covered by a thin mesh tissue. Two, three, four and five adults of Diabrotica speciosa (Germar) (Coleoptera, Chrysomelidae) were kept inside the cage on each plant by 24 hours. Leaf area consumption was measured by an area meter. Results showed that no percentage of leaf reduction caused damage in plant height. The 25% of leaf area reduction in plants with 10- and 17- days-old do not reduce the grain yield, however, all levels of leaf area reduction decreased significantly the grain yield if plants were 24 days-old or older. The results showed also that each D. speciosa adult caused 7.8%, 5.8% and 3.% of leaf area reduction on one, two and three week-old plants, respectively. It was also conclude that 25% of leaf area reduction to the 24 days after the germination can be to provoke a reduction of 21,7% in the grain yield of bean crop. KEY-WORDS: Insecta; damage level; Diabrotica speciosa. |

Um experimento foi conduzido em casa-de-vegetação, em Goiânia-GO, Brasil. Foram realizados cortes manuais nas folhas, eliminando-se 25%, 50% e 75% do limbo, em plantas de diferentes idades (10, 17, 24, 31 e 38 dias). Outro experimento foi conduzido para avaliar o potencial de dano causado por Diabrotica speciosa (Germar) (Coleoptera, Chrysomelidae), em diferentes estágios do desenvolvimento da cultura. As plantas foram protegidas por gaiolas e, após 24 horas, a área consumida pelos insetos foi determinada através de um medidor de área foliar. As desfolhas avaliadas no primeiro experimento não reduziram o porte e o vigor das plantas. Uma desfolha de 25% em plantas com 10 e 17 dias de idade não diminuiu a produtividade de maneira significativa, contudo, todos os níveis de desfolha em plantas com mais de 24 dias de idade reduziram a produtividade do feijoeiro. Os resultados mostraram também que cada inseto adulto de D. speciosa provocou 7,8%, 5,6% e 3,2% de redução foliar nas plantas com uma, duas e três semanas de idade, respectivamente. Concluiu-se ainda que uma desfolha de 25%, aos 24 dias após a germinação, pode provocar uma redução de 21,7% na produtividade do feijoeiro.
