| description | The cotton mealybug, Phenacoccus solenopsis (Tinsley) (Hemiptera: Pseudococcidae), has
become a widespread pest causing serious losses in several economically important crops,
articularly cotton. To the best of our knowledge this is the first record of cotton mealybug,
P. solenopsis as a new pest of potato plants in Egypt. The insect was noticed on potato
plants for the first time during the growing season of 2016 (mid-August 2016). Mealybug
specimens were collected from infested potato plants and identified as P. solenopsis. In an
attempt to control this insect pest species, seven insecticides viz. sulfoxaflor, abamectin
+ thiamethoxam, spirotetramat, thiamethoxam, imidacloprid, buprofezin, and pymetrozine,
belonging to different chemical groups, were tested for their effect against nymphs
and adult females of P. solenopsis on potato under field conditions. The obtained results
indicated that sulfoxaflor, abamectin + thiamethoxam and spirotetramat had the highest
efficacy against P. solenopsis recording 80.3–96.05% reduction of the insect population after
21 days of application. Thiamethoxam, imidacloprid, buprofezin and pymetrozine failed to
exhibit sufficient P. solenopsis control. |
