... weather. The male adult mealybugs possess two pairs of wings. Female have no wings and move by crawling short distances or by being blown in air currents. Female usually lays 100 to 600 eggs. Eggs are greenish-yellow in colour measuring 0.120 cm diameter and laid in an ovisac that 3-4 times the body length. Eggs are covered with white waxy substances developed ventrally by the adult female. Egglaying is continued up to 2 weeks and 150-200 eggs were deposited ...

Influence of the Host Plant on the Encyrtid Aenasius bambawalei, a Parasitoid used to Control the Cotton Mealybug, Phenacoccus solenopsis, in Pakistan

Hayat Badshah¹, Farman Ullah¹, Paul-André Calatayud², Hidayat Ullah³ and Bashir Ahmad¹

... parasitoids coming from mealybugs fed on hibiscus exhibited a significantly longer tibia and body weight than the parasitoids coming from the mealybugs reared on the other plants. The host plants did not influence the sex ratio of the 3^rd trophic level. The current study indicated that hibiscus is, among those tested in this study, the best plant species to mass rear the mealybug and its associated parasitoid in ...

Comparative Toxicity of some Selected Novel Chemistry Insecticides against Mealybug Drosicha mangiferae (Hemiptera: Pseudococcidae) Infesting Citrus Orchards in Pakistan

Hafiz Abdul Ghafoor*, Muhammad Afzal, Muhammad Luqman and Muhammad Zeeshan Majeed

...es against D. mangiferae mealybugs were sulfoxaflor, spirotetramat, thiamethoxam and pyriproxyfen with mean mortality and LT50 values of 64.00±3.50% and 31.67 h, 62.67±2.64% and 34.42 h, 53.01±4.10% and 45.84 h, and 51.00±3.97% and 48.10 h, respectively. Based on these results, the above mentioned novel chemistry insecticides are recommended to be incorporated in future pest management programs against D. mangiferae

...9%) in the population of mealybugs compared to the control trees. Furthermore, a maximum number of adult mealybugs (512) were recorded in Gunny bags wrapped on willow (S. wilhelmsiana M. Bieb) tree trunks among three types of forest trees during July 2020. In conclusion, soil racking and egg removal should be carried out simultaneously during winter for eco-friendly mealybug management.
