The distribution of false stable fly, Muscina stabulans (Harris)(Diptera: Muscidae) is worldwide. Control of M. stabulans has been seldom done; therefore, this study investigated some biological aspects post treatment of four essential oils through ingestion and contact bioassays against the 3rd larval instars of M. stabulans. Post treatment (PT) with 50%, the mortality% of larvae, pupae, both larvae and pupae, and adults reached 83.33, 73.33, 95.56, and 100%, respectively, for Apium graveolens (celery); 73.33, 75.00, 93.33, and 100.00%, respectively, for Eruca sativa (ruca);80.00, 100.00, 100.00, and 100.00%, respectively, for Lactuca sativa (lettuce); and 63.33, 81.82, 93.33, and 90.00%, respectively, for Raphanus sativus (radish).The pupation and adult emergence rates PT with 50%, and LC50 values were 4.44, 0.00, and 21.743%; 6.67, 0.00, and 24.786%; 0.00, 0.00, and 20.909%; and 6.67, 10.00, and 31.826%, respectively. On the other hand, their toxicity indices reached 96, 84, 100, and 66%, respectively. This study indicated that L. sativa was the most effective oil, followed by A. graveolens and E. sativa; whereas R. sativus was the least effective oil. To conclude, essential oils could be used as ecofriendly fly management in organic farming and in places where conventional insecticides could not be applied.
The false stable fly, Muscina stabulans (Diptera: Muscidae) is a cosmopolitan fly with a worldwide distribution and has medical and forensic importance in acting as a mechanical disease vector and intestinal myiasis producing fly. Control of M. stabulans is very rare; therefore, this study investigated some biological aspects post treatment of four essential oils through ingestion and contact bioassays against the 3rd larval instars of M. stabulans. After treatment with 50%, the mortality% of larvae, pupae, larvae and pupae, and adults reached 83.33, 73.33, 95.56, and 100%, respectively for Apium graveolens (celery); 73.33, 75.00, 93.33, and 100.00%, respectively, for Eruca sativa (ruca); 80.00, 100.00, 100.00, and 100.00%, respectively, for Lactuca sativa (lettuce ); and 63.33, 81.82, 93.33, and 90.00%, respectively, for Raphanus sativus (radish).The pupation and adult emergence rates, as well as LC50 values were 4.44, 0.00, and 21.743%; 6.67, 0.00, and 24.786%; 0.00, 0.00, and 20.909%; and 6.67, 10.00, and 31.826%, respectively. On the other hand, their toxicity indices reached 96, 84, 100, and 66%, respectively. This study indicated that L. sativa was the most effective oil, followed by A. graveolens and E. sativa; whereas R. sativus was the least effective oil. To conclude, essential oils could be used as ecofriendly fly management in organic farming and in places where conventional insecticides could not be applied.
