Summary
[edit]DescriptionLeptoglossus occidentalis - Western conifer seed bug - Amerikanische Kiefernwanze (29361190264).jpg |
In its native range, the Western Conifer Seed Bug feeds on the sap of developing conifer cones throughout its life, and its sap-sucking causes the developing seeds to wither and misdevelop. The animals are good fliers, flight way and the zoom similar to the flight of bumblebees. The western conifer seed bug is native to North America (west of the Rocky Mountains) but has in recent times expanded its range to eastern North America, and has become an invasive species in parts of Europe. Recent records suggest that interstate commerce has been a factor in extending the insect’s range. In Europe, this species was first reported in 1999 from northern Italy; it had probably been accidentally imported with timber and, as it seems, more than once, as its presence was subsequently reported from that country almost simultaneously from locations a considerable distance apart. By 2007, it had established itself in the northern Balkans (Slovenia and Croatia), the Alps (Austria, Switzerland), and parts of the Czech Republic, France, Germany and Hungary; in 2003, it was found to occur in Spain, though this population probably derives from a separate introduction, in late 2007, it was found in Poland; during the autumn of 2008, a large influx of this species arrived on the south coast of England, in late 2009, a large group of western conifer seed bugs invaded Istanbul, Turkey, the same thing happened in October 2012 in most of the cities of the French Alps. At the onset of cold weather, adult western conifer seed bugs may also enter buildings in search of protected overwintering warm sites, they frequently congregates on the outside of buildings in late summer and early fall. The large numbers of this insect observed around windows and doors of houses. The best method of control seems to be mechanical exclusion to prevent this insect’s invasion: replace loosely fitting screens, windows, and doors; caulk gaps around door frames, window frames, and soffits; caulk cracks behind chimneys and underneath the wood fascia; screen fireplace chimneys and attic and wall vents. Western Conifer Seed Bug питается на протяжении всей своей жизни соками хвойных шишек, что приводит к тому, что семена чахнут и развиваются неправильно. Жуки хорошо летают, по способу полета и звуку напоминают полет шмелей. Природный ареал жука- Северная Америка к западу от Скалистых гор, но в последнее время он имеет тенденцию распространения в восточную часть Северной Америки и стал инвазивным видом во многих частях Европы. Последние исследования говорят о том, что межгосударственная торговля была фактором в расширении диапазона распространения насекомого. В Европе этот вид был впервые описан в 1999 году в северной Италии; он, вероятно, был случайно импортирован с древесиной и, по-видимому, более чем один раз, так как о его присутствии впоследствии сообщили из этой страны почти одновременно из разных мест на значительном расстоянии друг от друга. К 2007 году он был обнаружен в северных Балканах (Словении и Хорватии), Альпах (Австрия, Швейцария), а также в Чехии, Франции, Германии и Венгрии. В 2003 году было обнаружено, что он есть и в Испании, хотя это, вероятно, произошло от отдельного ввоза. В конце 2007 - года Польша; в течение осени 2008 года большое количество на южном побережье Англии, в конце 2009 года большая группа в Стамбуле, Турция, в октябре 2012 года в большинстве городов во французских Альпах. С наступлением холодов взрослые насекомые стремятся попасть в здания в поисках теплых защищенных мест зимовки, они часто собираются на внешней стороне зданий в конце лета и начале осени. Большое количество этих насекомых наблюдается вокруг окон и дверей домов. Лучший метод контроля - создать механические препятствия, чтобы предотвратить их вторжение : улучшить изоляцию окон и дверей; заделать трещины, заэкранировать вентиляционные отверстия. |
