Psylla Alni
''Psylla alni'' is a species of psyllid, a plant-feeding hemipteran in the family Psyllidae. Distribution This species is present in the Palearctic realm (from Europe to Siberia and Sakhalin, Kazakhstan, Caucasus) and in the Nearctic realm (Canada and United States of America).

The nymphs are usually covered by white waxy secretions. In the 5th preimaginal stage nymphs can reach a length of about . Biology Adults can be found from June to October. This species has one generation a year (univoltine) and overwinters as an egg. It is monophagous on most Betulaceae (''Alnus glutinosa'', ''Alnus hirsuta'', ''Alnus incana'', '' Alnus japonica'', ''Alnus viridis ''Alnus alnobetula ...

Rubus
''Rubus'' is a large and diverse genus of flowering plants in the rose family, Rosaceae, subfamily Rosoideae, with over 1,350 species. Raspberries, blackberries, and dewberries are common, widely distributed members of the genus. Most of these plants have woody stems with prickles like roses; spines, bristles, and gland-tipped hairs are also common in the genus. The ''Rubus'' fruit, sometimes called a bramble fruit, is an aggregate of drupelets. The term "cane fruit" or "cane berry" applies to any ''Rubus'' species or hybrid which is commonly grown with supports such as wires or canes, including raspberries, blackberries, and hybrids such as loganberry, boysenberry, marionberry and tayberry. The stems of such plants are also referred to as canes. Description Most species in the genus are hermaphrodites, '' Rubus chamaemorus'' being an exception. ''Rubus'' species have a basic chromosome number of seven. Polyploidy from the diploid (14 chromosomes) to the tetrade ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pachypsylla Celtidisumbilicus
''Pachypsylla'' is a genus of psyllids. Species of the genus ''Pachypsylla'' lay eggs on the leaves of the ''Celtis occidentalis'' tree. Upon hatching, the young psyllids become encased in a gall which the young leaf parts grow in response to the infestation. Species The following species are recognised in the genus ''Pachypsylla'': *'' Pachypsylla celtidisasterisca'' Riley, 1890 *'' Pachypsylla celtidiscucurbita'' Riley, 1890 *'' Pachypsylla celtidisgemma'' Riley, 1885 – hackberry bud gall maker *'' Pachypsylla celtidisglobula'' Riley, 1890 *'' Pachypsylla celtidisinteneris'' Mally, 1894 *'' Pachypsylla celtidismamma'' (Riley, 1881) – hackberry nipplegall maker *'' Pachypsylla celtidispubescens'' Riley, 1890 *'' Pachypsylla celtidisumbilicus'' Riley, 1890 *'' Pachypsylla celtidisvesicula'' Riley, 1890 – hackberry blistergall psyllid *'' Pachypsylla cohabitans'' Yang & Riemann, 2001 *''Pachypsylla dubia ''Pachypsylla'' is a genus of psyllids.
