Resistance Level of Plutella xylostella L. (Lepidoptera: Plutellidae) on Cypermethrin in the Regency of Kupang
The diamondback moth, Plutella xylostella L. (Lepidoptera: Plutellidae) is one of the major pests of the Brassicaceae family. Presently, farmers mostly use insecticide to control this pest. The improper use of insecticide, however, may lead to target pest resistance. Resistance to pyrethroid (cypermethrin) insecticide cases have been widely reported. This research aimed to know whether the farmers use cypermethrin based on the recommended practices and to determine the resistance level of P. xylostella collected from Tarus, Noelbaki, Oesao and Pukdale Villages collected from the Kupang District, East Nusa Tenggara, which were then compared to the population of Cangkringan (Sleman, Yogyakarta) as a susceptible population. The survey showed that these four locations in Kupang, used insecticides intensively and did the mixing of two or three insecticides. Insecticide application in these four locations was mostly not scheduled as recommended on the label of insecticides. The susceptibility test showed that the RR (resistance ratio) value from Kupang (Tarus = 9.2, Noelbaki = 7.2, Oesao 7.3, and Pukdale = 3.8, respecively) was higher than susceptible population (Cangkringan = 1.0). Therefore, P. xylostella larvae collected from Kupang has been resistant to cypermethrin. IntisariPlutella xylostella L. merupakan salah satu hama utama pada tanaman Famili Brassicaceae (Cruciferae).
