In addition to being pests, aphids can act as plant disease vectors. Controlling this pest is essential to increase crop productivity and maintain economic value. Farmers typically use synthetic insecticides for pest control. However, the continuous use of synthetic insecticides can lead to aphids developing resistance. This study aims to assess the resistance levels of aphids in Serang City to various synthetic insecticides. The study utilized five synthetic insecticide active ingredients: carbamates, organophosphates, pyrethroids, neonicotinoids, and flupyradifurone, at concentrations of 5%, 50%, 95%, and 100%. The study measured LT50, LT99, and LC50 values for each synthetic insecticide and observed morphological changes in aphids. The results indicated that aphids in agricultural areas of Serang subdistrict, Serang City, showed resistance to organophosphate insecticides. Additionally, aphids in Cipocok subdistrict, Serang City, were suspected of developing resistance to pyrethroid insecticides. Higher concentrations of insecticides resulted in faster pest mortality. Based on the LC50 values, carbamate and neonicotinoid insecticides are recommended for controlling aphid pests (Aphis gossypii). The study also observed changes in behavior and morphology of aphid pests following insecticide application. date: 2025 type: Thesis type: NonPeerReviewed format: text language: en identifier: https://eprints.untirta.ac.id/47937/1/Kendra%20Aro%20Rinjani_4442210080_Fulltext.pdf format: text language: en identifier: https://eprints.untirta.ac.id/47937/2/Kendra%20Aro%20Rinjani_4442210080_01.pdf format: text language: en identifier: https://eprints.untirta.ac.id/47937/3/Kendra%20Aro%20Rinjani_4442210080_02.pdf format: text language: en identifier: https://eprints.untirta.ac.id/47937/4/Kendra%20Aro%20Rinjani_4442210080_03.pdf format: text language: en identifier: https://eprints.untirta.ac.id/47937/5/Kendra%20Aro%20Rinjani_4442210080_04.pdf format: text language: en identifier: https://eprints.untirta.ac.id/47937/6/Kendra%20Aro%20Rinjani_4442210080_05.pdf format: text language: en identifier: https://eprints.untirta.ac.id/47937/7/Kendra%20Aro%20Rinjani_4442210080_Ref.pdf format: text language: en identifier: https://eprints.untirta.ac.id/47937/8/Kendra%20Aro%20Rinjani_4442210080_Lamp.pdf identifier: ARO RINJANI, KENDRA (2025) RESISTENSI KUTU DAUN (Aphis gossypii) TERHADAP BERBAGAI JENIS DAN KONSENTRASI INSEKTISIDA SINTETIK.
