THE IMPACT OF Lantana camara???s LEAF EXTRACT TO PREDATORY INSECTS IN THE SOYBEAN FIELD

Article has been presented as the oral speaker in 4th ASEAN Science Congress and Sub Committee Conferences in Botanical Square Bogor, August 19, 2014The purpose of research to study the impact of Lantana camara???s leaf extract as the botanical insecticides to predatory insects in soybean field. The field experiment was conducted from June to September 2013 in Experimental Farm, Cereal Research Centre Maros District, South Sulawesi. The identify of soybean insect pests and their predatory were conducted in Plant Protection Laboratory, Dept. of Pests and Plant Diseases, Faculty of Agriculture Hasanuddin University, Makassar. We were applied the L. camara???s leaf extract concentration about 4% into soybean field. The research was used Randomized Block Design with four application treatment, respectively: (1) L. camara???s leaf extract fermentation. (2) L. camara???s leaf extract without fermentation, (3) application of synthetic insecticide with active compound of lambda cyhalothrin 1% and (4) control (used the distilled water). The results was showed the predatory insects in visual observation i.e. coccinellids (Menochilus sexmaculatus F.) (Coleoptera : Coccinellidae), damsel flies (Agriocnemis sp) (Odonata : Coenagrionidae) and mantids (Stagmomantis carolina L.) (Mantodea : Mantidae). The results from L. camara???s leaf extract without fermentation between M. sexmaculatus and Agriocnemis sp. similar 0,30 individual and 0,30 individual, respectively. Synthetic insecticide application with active compound lambda cyhalothrin 1% has a highest number of Agriocnemis sp. 0,19 individual, M. sexmaculatus 0,11 individual and S. carolina 0,01 individual, respectively. The control treatment used distilled water was showed the highest amount of M. sexmaculatus 0,32 individual, Agriocnemis sp. 0,31 individual and S. carolina 0,05 individual, respectively. We were recommended L. camara???s leaf extract as the botanical insecticides safety for predatory insects in soybean field
