Four insect species producing honeydew, exploited by bees, were found on wild pear trees,Pyrus amygdaliformis Vill.. Three of them were Psyllids,Cacopsylla (Hepatopsylla) notata (Flor),Cacopsylla (Thamnopsylla) pyrisuga (Förster), Cacopsylla (Hepatopsylla) pyri (L.), and one was Aphid,Dysaphis pyri D.d.F. The 1 rst one was the most abundant.Although these species are producing honeydew from spring to autumn, the bees are foraging on it only during September and October, and not every year.A… Expand

Predators and parasitoids of Cacopsylla pyri (L.) (Hemiptera: Psyllidae) in Serbia
TLDR
In the study, the species Psyllaephagus procerus, Syrphophagus ariantes and Tamarixia sp. Expand
The two spotted spider mite, Tetranychus urticae (Acari: Tetranychidae), alternative prey for the lacewing Dichochrysa prasina (Neuroptera: Chrysopidae)
The predatory lacewing Dichochrysa prasina Burmeister can feed and reproduce on various aphid species. However, other species such as the two spotted spider mite Tetranychus urticae Koch may serve asExpand
Biocontrol of pests of apples and pears in northern and central Europe: 2. Parasitoids.
TLDR
It is demonstrated that apple and pear pests are host to a large and varied parasitoid fauna and some effectively regulate pest populations in unsprayed and/or commercial (insecticide sprayed) apple or pear orchards either individually or as part of parasitoids guilds. Expand
Foliar Applications with Plant-Derived Extracts Control Pistachio Psyllid, Agonoscena pistaciae
TLDR
Citrus and palm trees’ extracts, commercially formulated as ProAlexin PNSTM and AgrisprayTM, were studied against the pistachio psyllid, Agonoscena pistaciae, in field conditions and mortality on the trees treated with these products was significantly higher compared with the control. Expand
True bugs (Hemiptera, Heteroptera) as psyllid predators (Hemiptera, Psylloidea)
TLDR
The aim of the research was to provide list of true bugs recorded as predators of psyllids in order to preserve their diversity and significance, especially on cultivated plants. Expand
Measuring pear psylla population density (Cacopsylla pyri L. and C. pyricola Förster): review of previous methods and evaluation of a new technique
TLDR
The data provided by the wash-down method was compared with the traditional limb beating method and it was possible to obtain real data about the absolute population density and its changes, as well as the susceptibility or tolerance of the pear cultivars to pear psylla. Expand
La madurez de las cubiertas vegetales aumenta la presencia de enemigos naturales y la resiliencia de la red trófica de la copa del olivo
TLDR
According to the analysis, a mature ground cover could provide the trophic network of the olive trees with new efficient taxa to enhance the biological control of pests. Expand
