Abstract
   To control pests and diseases, farmers usually apply insecticide once or twice a week, resulting in pest resistance, resurgence and secondary blasting. Thus it is necessary alternative control method which is more effective to reduce the negative impact of the insecticide, called Integrated Pest Management (IPM). One of the important control techniques is the use of natural enemies in the tomato planting ecosystem. The study aims to determine the type and parasitoid population and the parasitism percentage of L. sativae against pests in IPM and conventional treatment. Materials and tools used are tomato leaves, alcohol 70%, plastic containers, plastic bags, rubber bands, paper towel, distilled water, calculators, scissors, collecting bottle and boxes, dissecting, microscope, labels and stationery. Research using field experiments by comparing the population of natural enemies (parasitoids) on IPM and conventional plots. On IPM plot tomatoes were planted using plastic mulch and without synthetic insecticides, while on conventional plots the synthetic insecticides were used without plastic mulch. Results showed four types of parasitoids, Hemiptarsenus varicornis, Gronotoma sp., Opius sp., and Neochrysocharis sp. On IPM treatment, the average parasitism percentage of H. varicornis is 23.56%, while only 5.36% resulted on conventional treatment. Parasitoids H. varicornis has the potential as a pest control agent L. sativae because the population is higher than other parasitoids.
