![]() The authors conclude that the new pitfall trap design is more effective because it is much taller than the interceptor trap, which makes it more difficult for bed bugs to escape, and that the effectiveness can be further enhanced by adding attractants such as carbon dioxide, chemical lures, or heat. However, there were no significant differences between traps baited with CO2 derived from cylinders and CO2 derived from sugar and yeast, which is cheaper to produce. Traps baited with carbon dioxide also caught higher numbers of bed bugs, and higher rates of released CO2 were more effective than low rates. Traps with the experimental lure caught 2.2 times as many bedbugs as unbaited traps. The new pitfall trap design caught significantly more (2.8-fold) bed bugs than the Climbup insect interceptor trap, which the authors name as the most effective monitor currently available on the market. Various sources and levels of carbon dioxde were also tested as attractants. Through quantitative comparisons, we demonstrated that baited pitfall traps and flight interception traps captured complementary dung beetle communities with different functional traits. The baited kill traps (KB) are identical except that a bait bag hangs from a small. The lure mixture consisted of nonanal, 1-octen-3-ol, spearmint oil, and coriander Egyptian oil.

The new pitfall trap design was made with an inverted plastic dog bowl and the outer wall of the trap was covered with a layer of paper surgical tape which was dyed black. The three authors from the Rutgers University Department of Entomology, Narinderpal Singh, Changlu Wang, and Richard Cooper, report their findings in "Effect of Trap Design, Chemical Lure, Carbon Dioxide Release Rate, and Source of Carbon Dioxide on Efficacy of Bed Bug Monitors." Their findings suggest that an effective and affordable bed bug monitor can be made incorporating the new pitfall trap design, a chemical lure, and a sugar-and-yeast mixture to produce carbon dioxide, which is also known to attract bedbugs. The authors also found that traps baited with an experimental chemical lure mixture caught 2.2 times as many bed bugs as traps without the lure. view moreĪ new pitfall trap designed to capture bed bugs is more effective than those currently on the market, according to the authors of an article appearing in the next issue of the Journal of Economic Entomology. One of the easiest ways to catch beetles, but you must ensure that you check them daily. Making A Pitfall Trap A pitfall trap - insects fall in and they can't get back out. The Silphidae and Histeridae were more abundant in the maple forest, whereas the Hydrophilidae and Ptilidae were more abundant in the fir forest.Image: This image shows the experimental set up for determining the efficacy of a new pitfall trap design in a laboratory test. Apidae, Araneae, Carabidae, Diptera, Formicidae, Isopoda, Vespinae are all common catches in pitfall traps. Strong differences in species assemblages were also observed between the southern maple and fir forest sites. For the beetles caught in the meat-baited traps (majority of captures), decreases in abundance and species richness were observed from south to north along the fir forest transect, with evidence of decreasing specific diversity as measured by the Shannon index of diversity. All Histeridae, Hydrophilidae, Scarabaeidae, and Silphidae were identified to species to examine specific diversity variation among sites. Meat-baited pitfall traps caught nearly 15 times as many beetles as dung-baited traps. A total of 8,511 beetles were caught and identified to family level, 95.7% of which belonged to families with known coprophilous or necrophagous behavior. Beetle abundance was estimated using a sampling design comprising replicated pitfall traps baited with red deer meat or dung in each site. We studied selected assemblages of coprophilous and necrophagous beetles in Quebec along a 115-km north-south transect in three balsam fir (Abies balsamea (L.) Miller) forest sites and in a fourth forest site dominated by sugar maple (Acer saccharum Marshall), close to the southern fir site. The presence and abundance of beetles exploiting such resources are influenced by various ecological factors including climate and forest cover vegetation. Vertebrate dung and carrion are rich and strongly attractive resources for numerous beetles that are often closely linked to them.
