Abstract

Grey pineapple mealybug (Dysmicoccus neobrevipes) is a significant  pest in many  cultived plants. This insect causes chlorotic, necrotic, and stunted growth, and yield  losses. This study aimed  to determine  the most effective insecticides  for controlling D. neobrevipes. Identification  was performed morphologically and molecularly. Insecticide efficacy testing was conducted using a completely randomized design  consisting of five active ingredient  treatments (chlorpyrifos, carbosulfan, lambda-cyhalothrin, nitenpyram, buprofezin, and control) with three replications. The Dysmicoccus spp. on Aglaonema rotundum were identified  as D. neobrevipes  morphologically and molecularly. In general, insecticide treatments  significantly caused mortality  at the  tested  stages. The rate of egg hatch  suppression ranged from 18.3 to 52.2%  for all insecticides. Lamda-cyhalothrin and buprofezin  caused  the lowest mortality in the  nymphal (33.3-56.7%) and adult (23.3-36,7%) stages, while nitenpyram  caused the highest mortality in both  nymphal and adult stages (100%).  This study  also described  external morphological  changes in  D. neobrevipes adults treated with insecticides through scanning electron  microscopy. In conclusion, nitenpyram showed the highest  effectiveness compared to other insecticides, making it suitable to control  D. neobrevipes.
