Effects of irradiation on Planococcus minor (Hemiptera: Pseudococcidae).

Irradiation has been recognized and endorsed as a potential phytosanitary measure that could be an alternative to current quarantine treatments. Dosages of 50, 100, 150, 200, and 250 Gy were used to irradiate three different life stages (eggs, immatures, and adults) of Planococcus minor (Maskell) (Hemiptera: Pseudococcidae), focusing on females due to its parthenogenesis ability, with an aim to...

Susceptibility of Maconellicoccus hirsutus (Homoptera: Pseudococcidae) to methyl bromide.

Eggs, crawlers, early nymphs, late nymphs, and adults of the pink hibiscus mealybug, Maconellicoccus hirsutus (Green), were tested for their susceptibility to methyl bromide in 2-h laboratory fumigations at ambient conditions (25 degrees C, 95% RH). Dose-response tests indicated that the egg was the most susceptible life stage with an LC99 of 20.2 mg/liter. Based on probit analysis of dose-resp...

Identification of Mealybug- (Homoptera: Pseudococcidae) Resistant Turf-Type Buffalograss Germplasm

Two species of mealybugs, Tridiscus sporoboli (Cockerell) and Trionymus sp., have emerged as potentially serious pests of turf-type buffalograss, Buchloe dactyloides (Nuttall) Engelmann. Sixty-two buffalograss selections were screened for resistance to these mealybugs in 4 greenhouse trials. Using a 1-6 rating scale (1 = no signs of mealybugs, 6 = >75% of tillers infested), 'Prairie' and '609' ...
