Chemical meat bait traps versus basic meat bait traps in collection of adult flies

Abstract

The aim of the present study is to compare the effectiveness of chemical meat bait traps and basic meat bait traps for collecting adult flies. Bait traps used to collect these species can be damaged by anthropogenic or environmental effects. In this study, chemical meat bait traps and basic meat bait traps were hung from trees in the garden of the Ankara University Forensic Sciences Institute. This activity was carried out on the first Monday of each month for nine months. During the study, 1894 specimens were collected. Of all these species, 1787 (94.35%) were obtained from chemical meat bait traps (CMBTs), while 107 (5.65%) were obtained from basic meat bait traps (BMBTs). To determine the diversity of species in CMBT and BMBT sample groups in our study, Shannon Wiener and Simpson diversity and dominance indices were used. Shannon Evenness Index was calculated to determine the relationship between species community‐density. Cluster analysis provided a summary of the similarity in species composition of different regions. The CMBT and BMBT trap groups similarity/dissimilarity feature was checked using Bray–Curtis cluster analysis. The number of species collected from CMBTs was considerably higher than in BMBTs. The results of this study will help researchers to save time. In addition, it should be kept in mind that thiamethoxam is harmful to the environment when it contaminates sources of water.

A preliminary study on the distribution of necrophagous flies on Hainan Island, China

“…Pig lungs always have been used to investigate insect distribution in many studies in China [29][30][31]. In this article, we used plastic bottles as traps to collect the necrophagous flies, which was found to be effective and used in some similar studies [32,33].…”

Small Bait Traps May Not Accurately Reflect the Composition of Necrophagous Diptera Associated to Remains

“…They are generally baited with a small amount, being 50–200 g, of various animal organs such as pork muscle, pork liver, beef liver, chicken liver, or squid [ 1 , 12 , 15 , 16 ]. Synthetic compounds such as sodium sulfide, which act as constant chemical attractants to necrophagous Diptera, may also be used as bait, often with pork liver [ 8 , 11 , 13 , 17 , 18 ]. These small bait traps are emerging in forensic entomology as a method to record the local biodiversity of early-colonizing necrophagous Diptera species [ 1 , 15 , 19 ], which is known to vary according to the environmental conditions and the geographical region (e.g., [ 1 , 5 , 9 ]).…”
