Sažetak
Muskmelon, Cucumis melo L. is an annual cucurbit cultivated for its nutritional and medicinal fruits and seeds. The use of conventional insecticides for insect pest control on C. melo is deleterious to health and environment thus necessitating an Integrated Pest Management (IPM) approach. Decision making in IPM programs would, however, benefit greatly from insect diversity information. Even so, such information may be influenced by
crop type and insect collection method. Consequently, insect diversity and abundance as influenced by C. melo accessions (NHCmGm-1 and NHCmKn-1) and collection method (handpicking, sweep net and pitfall trap methods) were investigated. Seeds of both accessions were planted on raised bedsfollowing standard methods. Collection by handpicking was done from 3rd to 5th week after planting (WAP). In contrast, sweep net and pitfall trap methods were used from 6th to 10th WAP. The highest abundance of specimens on NHCmGm-1 and NHCmKn-1 respectively, belonged to order Hymenoptera (53.9% and 65.6%) and family Formicidae (40.2% and 29.1%). Insects in the order Hymenoptera also formed the majority of specimenscollected using handpicking (53.6%), sweep net (64.6%) and pitfall trap (59.6%) methods. Shanon’s diversity index (H) of specimen was significantly higher on NHCmGm-1 (1.9590) than on NHCmKn-1 (1.298). Specimens collected with pitfall traps had the highest abundance (721) but
the lowest H index (1.255). In contrast, insect collections with sweep nets had the richest species diversity (1.962). These results show that insect diversity and abundance in C. melo systems was significantly influenced by accession type and collection method.
