Xylosandrus Compactus
''Xylosandrus compactus'' is a species of ambrosia beetle. Common names for this beetle include black twig borer, black coffee borer, black coffee twig borer and tea stem borer. The adult beetle is dark brown or black and inconspicuous; it bores into a twig of a host plant and lays its eggs, and the larvae create further tunnels through the plant tissues. These beetles are agricultural pests that damage the shoots of such crops as coffee, tea, Theobroma cacao, cocoa and avocado. Description This beetle is dark brown or black. The adult female is up to long and about half as wide. The head is convex at the front with an indistinct transverse groove above the mouthparts. Each Antenna (biology), antenna consists of a funicle (base) with five segments and an obliquely truncated club slightly longer than it is wide. The pronotum is rounded with six or eight serrations on the front edge. The Elytron, elytra are convex and grooved and have fine perforations, and there are bristles betwe ...

Xylosandrus Germanus
''Xylosandrus germanus'', known generally as the alnus ambrosia beetle or black stem borer, is a species of ambrosia beetle in the family Curculionidae. ''X. germanus'' poses challenges in woody ornamental species and orchard crops such as apples and pecan. Furthermore, ''X. germanus'' is recognized or suspected to act as a vector for plant pathogens to varying extents, potentially leading to the decline of trees. The black stem borer is native to eastern Asia, but is an invasive species in Europe and North America. This species carries and feeds on associated ambrosia fungus, ''Ambrosiella grosmanniae''. Physiology ''Xylosandrus germanus'' are tiny insects, where females measure up to approximately 2 millimeters. The adult female is typically 2.3 times as long as wide. On the other hand, males are rarely found outside of the gallery system. The flightless ''X. germanus'' males are typically smaller than females and do not possess mycetangia. Males measure up to only approximat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
