Hydrogen is the central free intermediate in the degradation of wood by termite gut microbes and can reach concentrations exceeding those measured for any other biological system. Degenerate primers targeting the largest family of [FeFe] hydrogenases observed in a termite gut metagenome have been used to explore the evolution and representation of these enzymes in termites. Sequences were clone...
Many termite species typically fly during or shortly after rain periods. Local precipitation will ensure water will be present when establishing a new colony after the initial flight. Here we show how different species of termite utilise two distinct and contrasting strategies for optimising the success of the colonisation flight. Nasutitermes sp. and Microcerotermes sp. fly during rain periods...
microcerotermes diversus (silvestri) (isoptera: termitidae), an important wood pest in ahwaz (khuzestan, iran), causes serious economic damage to cellulosic products in buildings. to investigate the genetic diversity of this pest, 13 populations from different areas of khuzestan province as well as two samples from khark island and bandar abbas were collected. following dna extraction a fragmen...
Las termitas son insectos importantes por su participación en la descomposición de materia orgánica y el reciclaje los nutrientes suelo, sin embargo, algunas especies causan daños edificaciones, plantaciones forestales cultivos agrícolas, donde ocasionan pérdidas significativas. El objetivo este estudio fue realizar un listado comentado con claves identificación para las presentes sistemas agro...
The aim of this study was to describe the first records of termite activity on non-fossilized human bones in Brazil. The cases reported in this study resulted from forensic analysis of six human skeletons found in northeastern Brazil between 2012 and 2014. Traces of tunnels and nests commonly produced by termites were found on several human bone surfaces as well as the specimens and characteris...
موریانه Microcerotermes diversus (Isoptera: Termitidae) یک آفت مهم چوب در استان خوزستان بوده که خسارتهای اقتصادی جدی را به لوازم سلولزی وارد مینماید. به منظور بررسی تنوع ژنتیکی این آفت، 13 جمعیت از نقاط مختلف استان خوزستان به علاوه 2 نمونه از جزیره خارک و بندرعباس جمعآوری گردید. بعد از استخراج ژنوم، یک قطعه با طول 486 جفت باز از ژن میتوکندریایی سیتوکروم اکسیداز دو (COII) تکثیر و سپس تعیین تو...
Termites cause major economic losses by destroying agricultural crop trees. This study aims to survey the arboreal tree termites in Komkom community of Oyigbo Niger Delta. The area was divided into 10 zones and 306 trees were examined for presence termite nests, hollow sounds mud tubes. Samples with its nest, hollow, tube cuttings collected from infested using metal spatula, sorted identified. ...
Este estudo teve como objetivo verificar, em condições de campo, se os cupins arborícolas associados a espécies arbóreas presentes na Área Reserva da Ilha do Catalão UFRJ, RJ, exibem preferência para nidificação e forrageamento entre as árvores. Para isso, foram sorteadas aleatoriamente 95 linhas plantio árvores localizadas nessa área. Nestas foi percorrido um trajeto 100 m, também escolhido al...
