Abstract: Citrus seeds and peel contain certain compounds with varied level of bitterness. These compounds have been tested against insects and proved to be effective. The present study was therefore carried out to test the citrus seed extracts from 10 varieties against 4^th instar larvae of dengue fever mosquito, Aedes albopictus (Skuse). The results indicate that the extracts from rough lemon and lemon were more effective as larvicides with lowest LC₅₀ (119.993 and 137.258 ppm respectively, after 24h of exposure and 108.85 and 119.853 ppm respectively, after 48h of exposure) and LT₅₀ values (2.51 and 4.91h, respectively). Seed extracts from remaining citrus varieties were less active at lower doses; however at higher doses these were biologically active against Ae. albopictus. Our study has suggested that citrus-seed extract are environment friendly and can be used for managing Ae. albopictus larvae.
