“…Yellow was especially effective in capturing parasitic Hymenoptera (Thomson et al, 2004). Mondor (1995) reported that high numbers of hoverflies (Syrphidae) were caught by sticky red spheres in an apple orchard in Bremden, Manitoba, Canada.…”

Sticky colored traps have been widely used for sampling of harmful insects in wild and cultivated plants worldwide. Colored sticky traps could be a simple and a low-cost method for determining the relative abundance of harmful and beneficial insects, including pollinators. However, knowledge about catches of nontargeted insects such as pollinators by colored traps is rudimentary. Trials were conducted to evaluate the attractiveness of various colors (white, yellow, blue, and green) to some pollinating insects in apple in Adana Province, Turkey, during 2011 and 2012. Colored plates were hung at about 1.70 m from ground level of the exterior canopy of the selected trees at the beginning of their blooming and they were positioned toward the 4 cardinal directions. A total of 7 insect species belonging to the families Syrphidae (6 species, Diptera) and Apidae (1 species, Hymenoptera) were identified. Pollinating hoverfly Eristalis tenax L. and honey bee Apis mellifera L. were frequently captured, and significantly more of them were captured on white traps (P < 0.05). Blue and green colored traps were less attractive to both pollinator species. Cardinal directions did not have a significant effect on catches of E. tenax and A. mellifera on white traps. The use of white sticky traps may provide more ecological data for pollinators. However, using white colored traps for mass trapping of harmful insect species in fruit orchards may be risky due to reducing their numbers, particularly during blooming periods of the fruit orchards. Arrangements of sticky trap use prior to peak occurrence of the pollinators would be a better approach in terms of conservation of pollinators and sustainability of ecosystems.

“…For instance, in Californian and South African vineyards, the invasive Argentine ant, Linepithema humile (Mayr), can significantly enhance hemipteran pest densities (Addison & Samways 2000;Daane et al 2007). However, while ants form a major component of ground invertebrates in vineyards (Thomson et al 2004), little is known about their broader impact in Australian vineyards. While their relationship with honeydew-producing hemipterans is unclear (Chong et al 2010), ants may play important predatory roles in suppressing various life stages of light brown apple moth, Epiphyas postvittana Walker (Lepidoptera: Tortricidae) (MacLellan 1973;Frank et al 2007).…”

Ant diversity in Australia is exceptionally high compared to other regions of the world, with semiarid regions being the most species-rich. Ants perform numerous ecological functions and have been used in various biomonitoring programs. The role of ants in vineyards is unclear although other studies have focussed on controlling the invasive Argentine ant, Linepithema humile (Mayr), which significantly promotes mealybug and scale insect densities. While ants have been surveyed in a range of habitats throughout the continent, little is known about the diversity of ants in Australian vineyards. In this study, 147 native ant species were identified with pitfall trapping from 50 vineyards distributed in five regions in Victoria and South Australia. Species richness, compositional similarities and assemblage structure varied within and across regions although the ant fauna in semiarid vineyards was the most diverse. Linepithema humile was only detected in seven vineyards in one region. High ant diversity in vineyards could potentially contribute to ecosystem services, including biological control, and provide insurance to ecosystem functioning. Vineyards and other perennial agroecosystems could be important in maintaining invertebrate biodiversity particularly in a structurally diverse agricultural landscape.

“…Therefore, this trap method may be less efficient when monitoring cabbages in small field plots. Nevertheless, those traps proved effective for capturing very small, non-target insects, e.g., parasitic wasps, thrips, and species within Orius, which are not as easily identified during a visual survey Thomson et al (2004). have also shown that yellow sticky traps are suitable for monitoring small insects, such as Hymenopteran, Thysanopteran, and Hemipteran species.We determined that the composition of non-target arthropod species in the field did not differ between Bt and non-Bt plants.…”
