چکیده سوسک سر شاخه خوار رزاسه (osphranteria coerulescens) متعلق به راسته coleoptera و خانواده cerambycidae می باشد و یکی از گونه های بسیار مهم این خانواده در ایران بوده که اولین بار در سال 1323 از استان تهران جمع آوری و شناسایی شد. در سال های اخیر جمعیت این گونه در منطقه جنوب خراسان به شدت افزایش یافته و موجب خشک شدن و از بین رفتن تعداد زیادی از درختان میزبان گردیده است. لذا به منظور مطالعه بی...
The roles and chemistry of pheromones that mediate reproductive behaviors of cerambycid beetles have received remarkably little attention, given the economic importance of many cerambycid species. Until recently, very few volatile sex pheromones and nonvolatile contact pheromones had been identified. However, that situation is changing rapidly, with the number of identified pheromones more than...
Pine wilt is caused by the nematode Bursaphelenchus xylophilus, which is transported to host trees in the trachea of Monochamus spp. (Coleoptera: Cerambycidae). The study of the relationship between the nematode and its beetle vectors has been hampered by the inability to estimate nematode presence or density within live beetles. This report describes a rapid method for estimating nematode load...
The genera Anexodus Pascoe, 1866 and Pantilema Aurivillius, 1911 (Cerambycidae: Lamiinae: Morimopsini), both endemic to Borneo, are revised. Four species of Anexodus are recognized: A. aquilus Pascoe, 1886 (Malaysia: Sabah), A. sarawakensis Sudre, 1997 (Malaysia: Sarawak), A. syptakovaesp. n. (Malaysia: Sarawak), and A. tufisp. n. (Brunei). Pantilema is a monotypic genus containing P. angustum ...
First records of the tribes Anaglyptini and Tillomorphini (Coleoptera: Cerambycidae: Cerambycinae) are documented for Hispaniola. A new genus of a highly myrmecomorphic longhorned beetle (Licracanthagen. n.) is described and illustrated based on one species (Licracantha formicariasp. n.) and provisionally assigned to Tillomorphini. Three other new species of ant mimic longhorned beetles are des...
BACKGROUND The Cerambycidae are one of the largest beetle families. Cerambycid beetles are found on all continents, but the tropics are extremely rich in this species. The genus Criodion (Audinet-Serville, 1833) includes 13 species in the Neotropical Region, two of which occur in Central America. Panama has a high biodiversity, yet a small number of sites have been extensively studied. In this ...
Three-dimensional photonic-crystal grains were found in the scales of the longhorn beetle Prosopocera lactator (Cerambycidae). The local geometric structure can be described as a face-centered-cubic array of spheres, connected by short rods, reminiscent of the "ball-and-stick" models used by solid-state chemists to visualize atomic structures. Based on scanning electron microscopy, x-ray nanoto...
