ABSTRACT
Red mites [Panonychus citri (McGregor, 1916)] is one of the pests of the Citrus L. That causes yellow/brown spots on Citrus leaves. So far, farmers have dealt with chemical pesticides that contain compounds with high toxicity. The purpose of the study was to assess the effect of type and concentration of natural pesticides soursop (Annona muricata L.) leaves, papaya (Carica papaya L.) leaves, chrysanth(Chrysanthemum morefolium Ramat.) leaves on the persistence of red mites. This research was conducted at the Research Institute for Citrus and Tropical Fruit Plants in Batu City, East Java, Indonesia from July to September 2017. The study was a factorial experiment, the 1st factor is the type of natural pesticides: A1 = soursop leaves, A2 = papaya leaves, A3 = chrysanth leaves. The 2nd factor is the concentration of natural pesticides: B1 = 5 %, B2 = 10 %, B3 = 15 %. Pesticide persistence was observed based on the mortality rate of the red mite phase of the imago. The results showed that the pesticide persistence test of imago had the highest mortality rate for the treatment 2 × 24 h after pesticide spraying. Each pesticide treatment showed significant differences in the persistence of imago red mite. Papaya leaf pesticide treatment of a concentration of 15 % was effective in suppressing imago red mite 80 %. The 10 % concentration of chrysanth leaf pesticide was effectively suppressing the imago red mite 80 %. Soursop leaf pesticide treatment of a concentration of 5 % was effective in suppressing imago red mite 82 %.
