By-catches from bark beetle monitoring 2013

In 2013, a book printer monitoring with 20 pheromone traps was carried out by the University of Natural Resources in Gesäuse National Park. By-catch evaluation by the ÖKOTEAM (i.e. without book printers, copper cutters and the common ant colored beetle as the most important bark beetle counter-player) resulted in 146 beetles, 35 bugs, 16 cicadas, 14 spiders and 2 weaver knitting species. Among the beetles there are only a few more bark beetles antagonists. Well-known predators of Scolytinae are the black-brown ant colorful beetle and two bark glossy beetle species. A bedbug species specialising in bark beetle, the Beautiful Saw Leg, was detected in 32 specimens. The animals live in the beetles, where they suck eggs, larvae and dolls.2013年，自然资源大学（University of Natural Resources）于格赛泽国家公园（Gesäuse National Park）布设20个信息素诱捕器（pheromone traps），开展书蛀虫（book printer）监测工作。ÖKOTEAM对非目标捕获物进行评估（排除书蛀虫、铜切甲以及作为树皮甲虫主要天敌的常见蚁色甲虫），共获取146只甲虫、35只蝽类、16只蝉类、14只蜘蛛以及2种织叶蚁类物种。在捕获的甲虫类群中，树皮甲虫的天敌仅占少数。小蠹亚科（Scolytinae）的已知天敌包括黑褐蚁色甲虫与2种光滑树皮甲类物种。本次共采集到32头专门捕食树皮甲虫的蝽类——美丽锯足蝽（Beautiful Saw Leg），该类昆虫寄生于树皮甲虫体内，以其卵、幼虫及蛹为食。
