The Effectiveness of Pineapple Peel Extract (Ananas comosus L. merr) as Natural Larvicides of culex sp. Larvae

Culex sp. is known to be a type of vector for filariasis. A filarial worm is the cause. The most common method of controlling insects is with synthetic insecticides. Synthetic compounds are hazardous for both the environment and exposed users. The development of environmentally friendly and readily biodegradable pesticides is therefore essential. The study aimed to determine how well pineapple extracts worked as natural larvicides for Culex larvae. The Aceh Health Polytechnic Laboratory served as the site of the investigation. This type of research is experimental research, using a sample of 625 Culex larvae. Each treatment contained 25 larvae, performed five repetitions, and had an observation time of 12 hours. Extract concentrations were 2%, 4%, 6%, and 8%. The analysis employed the T-test to compare each extract, the Least Significant Difference (LSD) test to identify significant differences, and the ANOVA test to ascertain the difference in treatment averages. The average concentration of pineapple peel extract varied in their effects on Culex larvae mortality, according to the study's findings. Larvae were killed in 77.6% of cases by an 8% concentration of pineapple peel extract. Results showed that the extracts of pineapple, with an average of 7.40 larvae from pineapple peel. Culex larvae can be killed more effectively with pineapple peel extract. Keywords: Culex sp., pineapple peel, larvicide
