本研究旨在确定季节对甘佩拉猪腐肉相关昆虫多样性和动态的影响。高原中部地区,布基纳法索,西非。猪尸体(SusscrofadomesticusL.)暴露在开放区域,以监测其分解过程以及在温暖干燥期间(2015年3月至4月)被昆虫定殖,温暖潮湿期(2015年8月至9月)和凉爽干燥期(2015年12月至2016年1月)。每个研究期间进行60天的监测和昆虫学数据收集。分解过程总是包括五个阶段(新鲜,腹胀,腐败,产后,和骨骼),其持续时间根据研究期间的不同而不同。总之,属于4目的118,761种昆虫,12个家庭,17属,在三个研究期间收集了21个物种,大约61%的个体在温暖和潮湿的时期收集。与猪car体相关的昆虫种群动态在每个研究期间包括两个峰。Formicidae是每个研究时期最丰富的昆虫科,但是家蝇是最丰富的物种。发现列出的物种属于四个营养类群,主要是捕食者/食肉动物,其次是食性昆虫。命令,家庭,在温暖和潮湿的时期,本研究报告的营养类群明显更丰富。结果表明,卡利科的使用前景,Muscidae,在刑事调查中,取决于苏丹-萨赫勒地区的季节性变化。
This study aimed to determine the effects of seasons on the diversity and dynamics of insects associated with pig carrion in Gampela, Plateau Central Region, Burkina Faso, West Africa. Pig carcasses (Sus scrofa domesticus L.) were exposed in an open area to monitor their decomposition process and their colonization by insects during a warm and dry period (March-April 2015), a warm and wet period (August-September 2015) and a cool and dry period (December 2015-January 2016). Monitoring and entomological data collection occurred for 60 days for each study period. The decomposition process always included five stages (fresh, bloating, putrefaction, postputrefaction, and skeletal), which varied in duration depending on the study period. In sum, 118,761 insects belonging to 4 orders, 12 families, 17 genera, and 21 species were collected during the three study periods, with approximately 61% of the individuals collected during the warm and wet period. The dynamics of insect populations associated with the pig carcasses included two peaks at each study period. Formicidae was the most abundant insect family in each study period, but Musca domestica was the most abundant species. The listed species were found to belong to four trophic groups with a predominance of predators/carnivores followed by necrophagous insects. The orders, families, and trophic groups reported in this study were significantly more abundant during the warm and wet period. The results show prospects for the use of Calliphoridae, Muscidae, and Dermestidae in criminal investigations, depending on seasonal variations in Sudano-Sahelian areas.
