Abstract Invasive eucalypt psyllids pose a threat to the long‐term production of eucalypts worldwide. In order to reduce their economic impact, classical biological control using Psyllaephagus species has been used successfully. The objectives of this study were to determine the host specificity and host stage preference of Psyllaephagus blastopsyllae,

Pest categorisation of Coccus viridis
Abstract The EFSA Panel on Plant Health performed a pest categorisation of Coccus viridis (Hemiptera: Coccidae), the green coffee scale, for the territory of the European Union (EU), following the commodity risk assessment of Jasminum polyanthum from Uganda, in which C. viridis was identified as a pest of possible concern to the EU.

SELECTIVITY OF INSECTICIDES TO Encarsia hispida (Hymenoptera: Aphelinidae) [PDF]
ABSTRACT The use of non-selective insecticides in agricultural production can reduce or eliminate biological agents that regulate insects that are undesirable to humans in production processes. Here, the toxicity of synthetic products on the parasitoid Encarsia hispida was evaluated, the host of which is the whitefly, Bemisia tabaci biotype B, found on

Dicyphus hesperus, a zoophytophagous predator, effectively controls Bemisia tabaci in tomato greenhouses. Highly zoophagous lines rapidly reduced whitefly populations without causing significant damage to tomatoes, whereas lowly zoophagous lines were equally efficient over time but caused more damage.

Growing interest in optimizing biocontrol traits, particularly due to Nagoya Protocol constraints, necessitates understanding their heritability and genetic variation. This systematic review of 5209 studies on arthropod biocontrol agents yielded 94 relevant articles, with 42 providing heritability values.
