Resumo
O objetivo deste trabalho foi determinar a distribuição vertical e sazonal do percevejo-de-renda, Leptopharsa heveae Drake & Poor, 1935 (Hemiptera: Tingidae), em plantio de seringueira, Hevea brasiliensis Müell Arg., localizado em Pindorama, SP. A amostragem foi efetuada considerando-se folhas situadas nos lados norte e sul e na metade interna e externa de ramos nos terços inferior, médio e superior das plantas. As ninfas foram abundantes de março a maio e de outubro a novembro, fato igualmente verificado com adultos, de março até início de julho e durante novembro. Constatou-se que L. heveae distribuiu-se similarmente nas diferentes partes das seringueiras, o que facilita a amostragem. Assim, ninfas e adultos podem ser amostrados em folhas localizadas na parte externa de ramos presentes no terço inferior, lado norte ou sul, de seringueiras.
The objective of this work was to determine the within-plant and seasonal distributions of Leptopharsa heveae Drake & Poor, 1935 (Hemiptera: Tingidae) in rubber tree, Hevea brasiliensis Müell Arg., located in Pindorama, SP. The sampling was carried out considering leaves of internal and external parts of branches located in the upper, medium and lower sections of the north and south sides of rubber trees. The highest density of nymphs was observed from March to May and from October to November, the same occurring in adults from March to July and during November. The similar distribution of L. heveae on the different parts of the rubber trees facilitates sampling activities. Nymphs and adults can be sampled from leaves on the external part of branches located in the lower section of the north or south side of rubber trees.
