Meiosis in rare males in parthenogenetic Cacopsylla myrtilli (Wagner, 1947) (Hemiptera, Psyllidae) populations from northern Europe
For studying meiosis in males, large samples of Cacopsylla myrtilli (Wagner, 1947) (Hemiptera, Psyllidae) were collected in Norway, Sweden, Finland and northwest Russia. In addition to all-female populations, males were present in 10 out of 47 populations; still, all populations were highly female-biased, the proportion of males varying from 0.1% to 9.1%. These males are thus rare or so-called ...
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 کاملElicitors of Host Plant Defenses Partially Suppress Cacopsylla pyricola (Hemiptera: Psyllidae) Populations Under Field Conditions
Defense elicitors are products that activate acquired defense responses in plants, thus rendering the plants less susceptible to attack by a broad range of pests. We demonstrated previously under laboratory conditions that foliar applications of the defense elicitors Actigard (acibenzolar-S-methyl), Employ (harpin protein), or ODC (chitosan) to potted pear trees (Pyrus communis L.) each caused ...
متن کاملFunctional 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 کاملبازتوصیف پسیل کمتر شناخته‌شده، Cacopsylla dissimilis (Baeva, 1963) comb. nov. (Hemiptera: Psyllidae)، از ایران
طی مطالعه فونستیک پسیلها (Hemiptera: Psyllidae)در استان کرمان در بهار 1394، گونه Cacopsylla dissimilis (Baeva) comb. nov. از روی درخت بید، Salix pycnostachya،جمعآوری شد. این گونه قبلاً فقط از تاجیکستان گزارش شده بود و در این تحقیق برای اولین‌بار از ایران گزارش میشود. همچنین، گونه میزبان گیاهی آن، Salix pycnostachya، گزارش جدیدی محسوب میشود. ویژگیهای ریختشناختی حشرات بالغ و پورههای سن پن...
