Resumen

AFZAL, Muhammad et al. Susceptibility of six chemical insecticides against brown planthopper, Nilaparvata lugens (Hemiptera: Delphacidae) in Kallar tract of Punjab, Pakistan; 2015-2019. Enfoque UTE [online]. 2022, vol.13, n.4, pp.39-46. ISSN 1390-6542.  https://doi.org/10.29019/enfoqueute.867.

Brown planthopper (BPH), Nilaparvata lugens (Stål) (Hemiptera: Delphacidae) is an economically important insect pest of rice crop worldwide including Pakistan. The use of chemicals insecticides to control the BPH population has been considered an effective strategy. However, long-term and intensive use of insecticides has resulted in resistance against this pest. In this study, six recommended insecticides were tested against BPH over the period of 2015-2019 to determine the susceptibility level. From 2015-19, susceptibility of BPH was reduced to all tested insecticides. Increasing trend of LC50 values was recorded in fipronil (18.23-35.11 mg/L), imidacloprid (64.22-128.8 mg/L), buprofezin (185.01-315.0 mg/L), chlorantranilipyrole (199.2-263.3 mg/L), pymetrozine (248.2-315.5 mg/L), and nitenpyram (21.07-34.3 mg/L) respectively from 2015 to 2019. Correlation coefficient values indicated a significant relation (P < 0.05) between fipronil, imidacloprid, and buprofezin. The study will be helpful for resistance management strategies to prevent the resistance development in BPH against insecticides.
