Zusammenfassung:The leafminer Liriomyza sativae Blanchard is an important insect pest on melon crops in Brazil However, the information about its biology on melon (Cucumis melo L.) is scarce. Therefore, the aim of this research was to know some biological aspects of this pest, reared on melon plants, under laboratory conditions at 250C. Our results showed that the biological cycle of L. sativae lasts 15.9 ± 0.04 days (eggadult), namely: egg (2.7 [+ or -] 0.01 days), larva (4.1 ± 0.03 days) and pupa (9.1 ± 0.03 days). The sex ratio is 0.51 and the females live (19.3 ± 1.09 days) longer than males (16.2 ± 0.96 days). These results can help in the integrated management of L. sativae on melon crops and improve the systems for rearing this leafminer in laboratory. Key words: insect pest, Cucurbitaceae, biology, semiarid. A mosca-minadora Liriomyza sativae Blanchard e uma praga importante em cultivos de meloeiro (Cucumis melo L.) no Brasil. No entanto, as suas informacoes sobre biologia, em meloeiro, sao escassas. Portanto, o objetivo deste trabalho foi conhecer alguns aspectos biologicos dessa praga, criada em plantas de meloeiro, em condicoes de laboratorio a 250C. As informacoes obtidas mostram que o ciclo biologico de L. sativae e de 15,9 [+ or -] 0,04 dias (ovo-adulto), sendo: ovo (2,7 ± 0,01 dias), larva (4,1 ± 0,03 dias) epupa (9,1 ± 0,03 dias). A razao sexual e de 0,51 e as femeas vivem mais tempo (19,3 ± 1,09 dias) que os machos (16,2 [+ or -] 0,96 dias). Essas informacoes podem auxiliar na adocao de medidas de manejo integrado de L. sativae em cultivos de meloeiro e melhorar os sistemas de criacao da mosca minadora em laboratorio. Palavras-chave: inseto praga, Cucurbitaceae, biologia, semiarido.
