Red spinach (Alternanthera amoena) is one of the vegetable commodities that many people in demand for consumption because of its high nutritional content. Efforts to increase the production of red spinach often experience various obstacles. The main obstacle that limits the productivity of red spinach in the tropics is the number of Plant Disturbing Organisms  in the form of pests and potential diseases that can attack and decrease the production of spinach. One of the pests that often attack spinach is the existence of army worm (Spodoptera litura F.). Therefore, farmers need a way to eradicate the pest. This research is experimental using Random Complete Group. The data obtained were analyzed with variant analysis (ANOVA) in one direction and continued with LSD (Least Significant Different) test. Provision of botanical insecticide done by spraying the extract of leaves and seeds mimba with concentration dose 0%, 5%, 10% and 15%. In the final analysis of mortality data of army worm (Spodoptera litura F.) treated with mimba leaf extract obtained significant value of 76.263 at a significant level of 0.05 so it can be concluded that there is influence of mimba leaf extract on mortality of army worm. In the final analysis of mortality data of army worm (Spodoptera litura F.) treated with mimba seed extract obtained significant value of 78.625 at a significant level of 0.05 so it can be concluded that there is an effect of mimba seeds extract on mortality army worm.   Keywords: mimba leaf extract,  mimba seed extract, red spinach (Alternanthera amoena), army worm (Spodoptera litura F.), botanical insecticide

One of soybean problem in Indonesia is leaf damage caused by the Spodoptera litura. The aim of the study was to identify the resistance of soybean genotypes againts army worm based on the preference index and morphophysiological characters. 150 soybean genotypes were grown under field condition from February to May 2018 in Malang (East Java, Indonesia). The preference test was conducted in the laboratory using G100H as resistant reference plant to armyworm. The result showed that the preference index was ranged from 0.09-1.82. A total of 105 genotypes showed a low preference index (resistant), 39 genotypes showed a high preference index (susceptible), and a genotype has similar preference index with the reference plant (has equal resistance with G100H). Based on the preference index and morphophysiological characters, 150 soybean genotypes can be grouped into eight clusters. A genotype from cluster VIII (Anjasmoro/Rajabasa-41) has characteristics of low leaf water content, dense leaf trichomes, and the preference index of 0.14. Those characteristics could be the attributes of the soybean genotypes that is resistant to S. litura. The Anjasmoro/Rajabasa-41 was recommended to be cultivated in Indonesian, or may be used as a gene source in the breeding program for S. litura resistance

Comparative toxicity of Andrographis paniculata (leaves), Anethum graveolens (leaves), Azadirachta indica (fruits), Cassia fistula (seeds), Cuscuta reflexa (stem), Dendropthoe falcata (leaves), Lantana camara (leaves and fruits), Melia azedarach (leaves) and Vitex negundo ( stem) plant extracts against 2nd days (first instar) and 6th days(third instar) old larvae of Spodoptera litura was studied at 5 and 10mg/ml concentration. D. falcata leaves (98.58%) and A. indica fruits= C. reflexa (85.72%) were most effective in reducing weight gain in 2nd days old larvae at 5mg/ml and at 10mg/ml, C. reflexa (98.58) followed by C. fistula seeds and L.camara fruits(both 92.86%) were effective in retarding growth. L.camara fruit extract (99.43 and 99.93%) showed greater toxicity and reduced growth as compared to A. graveolens leaves (76.16% ) at 5mg/ml. At 10mg/ml L.camara (99.94%) and A. paniculata (89.54%) leaves exhibited reduction in weight gain over control against 6d old larvae. All the medicinal plants showed varying degree of toxicity. D.falcata, A.indica and L.camara exhibited high larval mortality as compared to the other plant extracts.
