Mealybugs are insects belonging to the family Pseudococcidae. This includes many plant-pest species with similar morphologies, which may lead errors in mealybug identification and delimitation. In present study, we employed molecular-species-delimitation approaches based on distance (ASAP) coalescence (GMYC mPTP) methods identify mealybugs collected from coffee other plant hosts states of Espír...

Abstract The absence of natural enemies in newly invaded areas is a key factor the successful invasion alien species. Whether specific parasitoid can be domesticated to attack nonnatural host that has no reported parasitic invasive remains unclear. Here, we analyzed two mealybugs (PSS- Phenacoccus solenopsis and PSI- solani ) P. ( Aenasius arizonensis verify this hypothesis under laboratory con...

Eight plant essential oils were extracted and tested for their efficiency as natural insecticides against the cotton mealybug, P. solenopsis (Tinsley). In-vitro bioassay, contact toxicity of to adult females 2nd instar nymphs was determined. Also, repellence activity tested. The most effective oil female’s after 72 hrs application L. nobilis followed by Apium graveolens, M. longifolia, C. artic...
