Studies were conducted in large arenas and simulated kitchens to compare the effectiveness of eight traps (seven sticky traps and one jar trap) and Þve attractants formonitoringGerman cockroaches (Blattella germanica L.). The evaluated traps were Trapper (type 9110Ð1), Catchmaster 150, 1001, and 2881, Victor-M330, Victor-M327, Glue board in D-Sect station, and a baby food jar trap. In choice te...

Steel foothold traps are widely used throughout North America to manage and harvest furbearers. Payne (1980) listed 6 incentives for furbearer harvest, 1 of which is to carry out "nuisance" control. The U.S. Fish and Wildlife Service (USFWS) has legislative responsibility for managing coyotes (Canis latrans) that cause damage to livestock (U.S. Fish and Wildl. Serv. 1978), and trapping is a pri...

Ecological traps, which occur when animals mistakenly prefer habitats where their fitness is lower than in other available habitats following rapid environmental change, have important conservation and management implications. Empirical research has focused largely on assessing the behavioural effects of traps, by studying a small number of geographically close habitat patches. Traps, however, ...

The relative performance of a clear delta trap baited with individual or combination sex pheromone and kairomone lures for codling moth, Cydia pomonella L., was evaluated against three vertical clear pane and colored delta traps in field trials within apple, Malus domestica (Borkhausen). The clear caught significantly more moths of each sex than an orange delta trap when baited with ethyl (E,Z)...

Among carnivorous plants, Darwin was particularly fascinated by the speed and sensitivity of snap-traps in Dionaea and Aldrovanda. Recent molecular work confirms Darwin's conjecture that these monotypic taxa are sister to Drosera, meaning that snap-traps evolved from a 'flypaper' trap. Transitions include tentacles being modified into trigger hairs and marginal 'teeth', the loss of sticky tenta...

BACKGROUND Field trapping experiments were conducted to evaluate the attractiveness of five different pheromone blends as well as the impact of trap design on attractiveness towards cocoa mirids, Sahlbergella singularis Hagl. and Distantiella theobroma (Dist.), in Cameroon. RESULTS A total of 361 adults of S. singularis (359 males and two females) were caught. The highest numbers of mirids we...

The effectiveness of two lures for trapping the small hive beetle, Aethina tumida, by means of in-hive traps was tested by field trials in apiaries located in Florida, Delaware, and Pennsylvania during 2003-2005. Both lures included a mixture (pollen dough) consisting of bee pollen and commercial pollen substitute formulated with or without glycerol and honey. Before it was used in the traps, t...

Four commercial sticky fluorescent yellow rectangle traps differing in shades of yellow, fluorescence, and other features were compared for capturing apple maggot fly, Rhagoletis pomonella (Walsh). Traps were the Alpha Scents Yellow Card (Alpha Scents), Pherocon® AM (Pherocon), Multigard® AM (Multigard), and the StikyTM Strips Insect Trap (Olson, small and large sizes), all baited with the same...
