The Sucking Pest WG was formed in 2008 to develop and disseminate IRM strategies for major sucking pests of global importance. It is recognised that this is a broad remit given the range of crops and pests, but by focusing on specific areas, the team is convinced that it can deliver strategies for key pests such as whiteflies, aphids and thrips, before moving on to consider other groups. The Sucking Pest WG absorbed the earlier Neonicotinoid WG in 2009…
…can be used foliarly or applied at the base of the plant in the root zone. While most insecticides are effective and have not shown cross resistance, resistance to some products exists. There is no listed IRAC susceptibility test method available for scales SYNONYMS Aonidiella perniciosa Aspidiotus perniciosus Diaspidiotus perniciosus Quadraspidiotus perniciosus EPPO Code: QUADPE The first documented case of resistance to insecticides was reported in populations of Comstockaspis perniciosa in 1914. More recently, resistance has developed to organophosphates….
…plants are most vulnerable after seedling emergence, but reduction in corn yield can still occur through leafhopper attacks during the vegetative period. Foliar and seed applied insecticides are the principal control method for this pest, with multiple applications being made during the vegetative period to prevent virus transmission. SUSCEPTIBILITY TEST METHOD No validated IRAC Method (July, 2024) Machado et al (2024) provides a description of a leaf-dip bioassay based on IRAC Method 19 with some adaptation. High levels of resistance…
