Functional response of Anthocoris nemoralis (Hemiptera: Anthocoridae) to the pear psylla, Cacopsylla pyricola (Hemiptera: Psyllidae): effect of pear varieties
Anthocoris nemoralis (F.) (Hemiptera: Anthocoridae) is one of the most prominent predators of the pear psylla, Cacopsylla pyricola (Forster) (Hemiptera: Psyllidae) and is considered as a biological control agent against this pest. In order to investigate the effects of plant varieties on predation of C. pyricola by A. nemoralis, the functional response of both the sexes of A. nemoralis to pear ...
متن کاملEcological and Genetic Differences between Cacopsylla melanoneura (Hemiptera, Psyllidae) Populations Reveal Species Host Plant Preference
The psyllid Cacopsylla melanoneura is considered one of the vectors of 'Candidatus Phytoplasma mali', the causal agent of apple proliferation disease. In Northern Italy, overwintered C. melanoneura adults reach apple and hawthorn around the end of January. Nymph development takes place between March and the end of April. The new generation adults migrate onto conifers around mid-June and come b...

متن کاملResistance to Pear Psylla Nymphal Feeding of Germplasm from Central Europe
Pear psylla (Cacopsylla pyricola Foërster) is the most serious pest of the European pear (Pyrus communis L.) in the production regions of Europe and North America. Nine plant germplasm introductions of pear from Central Europe recently released from plant quarantine were evaluated for nymphal feeding antixenosis, a primary mode of resistance known to be correlated with ovipositional antixenosis...
متن کاملStability of Cacopsylla pyricola (Hemiptera: Psyllidae) Populations in Pacific Northwest Pear Orchards Managed with Long-Term Mating Disruption for Cydia pomonella (Lepidoptera: Tortricidae)
This study focused on conservation biological control of pear psylla, Cacopsylla pyricola, in the Pacific Northwest, USA. We hypothesized that insecticides applied against the primary insect pest, codling moth Cydia pomonella, negatively impact natural enemies of pear psylla, thus causing outbreaks of this secondary pest. Hence, the objective of this study was to understand how codling moth man...
