“…Both sexes of D. platura and D. florilega preferred white water traps to blue or yellow ones (Laska et al , 1986). In British Columbia white sticky traps were more effective at trapping both onion fly and bean seed fly than either yellow sticky traps or onion‐baited yellow sticky traps (Vernon et al , 1998, 1989). Different colour water and sticky traps should be evaluated for onion fly and bean seed fly in the UK.…”

“…For bean seed fly, white water traps were generally better than yellow (Laska et al , 1986; Finch 1992). Onion fly has been trapped effectively using yellow water traps baited with half‐peeled onion (Finch et al , 1986) and Vernon et al (1989) used a vertical two‐sided sticky trap consisting of non‐ultraviolet reflective white painted cardboard. Cone traps have also been used for Delia spp.…”

Bean seed fly and onion fly are significant pests of alliaceous crops in the UK. Their activity was monitored using yellow water traps at three field sites in England in 2002 and 2003. Bean seed fly were not split between Delia platura or Delia florilega because from the growers point of view control measures are independent of species. The traps were effective at catching bean seed fly, which was present from April until September. A total of 1729 bean seed fly were trapped in 2002 and 4501 in 2003, with peak activity in May in both years. In 2003, there appeared to be three to four peaks in abundance of the pest. Only 113 onion flies were trapped in 2002 and 23 in 2003. More male onion fly were trapped than females. Pot experiments were carried out to evaluate efficacy of a range of insecticides, garlic and two parasitic nematode species (Steinernemafeltiae and Steinernema kraussei) against bean seed fly and onion fly. Pots of salad onions were exposed to natural oviposition by bean seed fly, but the onion fly experiment was carried out in a glasshouse with eggs of the pest being inoculated into the pots. Tefluthrin seed treatment appeared to be especially effective at preventing bean seed fly damage and produced the most robust seedlings but did not appear to kill the larvae. A drench of chlorpyrifos at the ‘crook’ stage gave 100% control of bean seed fly larvae. A chlorpyrifos drench was the only treatment to give effective control of onion fly. There was some evidence that the parasitic nematode S. feltiae reduced numbers of bean seed fly larvae by about 50%. Guidelines for control of both bean seed fly and onion fly are discussed.

“…Differences in the exposure of cylinders and cones to flies above and below the height of spheres, cubes and hemispheres are unlikely to influence our results, because Vernon et al (1989) showed that there was no significant difference in the response of females to traps placed at heights of 5 to 60 cm above ground in an onion field. In addition any slight reduction in the number of flies flying near the top of cylinders and cones would be offset by the increased numbers of flies flying near the bottom of these traps beneath the canopy (Vernon et al, 1989).…”

Using various three‐dimensional traps alone and in combination with the onion volatile, dipropyldisulphide (Pr2S2), we found that visual behaviour of female onion flies, Delia antiqua (Meigen), varied with the ‘visual context’ (background composition and trap spacing) in which traps were presented and the females' reproductive state (mated vs. unmated). Against a background of real onions, females alighted more frequently on spherical than cylindrical traps, and white than green spheres, but females responded equally to white and green cylinders. In an onion field, baiting traps with Pr2S2 significantly increased female response to white over green traps, but had no influence on their response to trap shape. When traps were spaced 10 m apart and against a background of bare soil, females orienting to Pr2S2 baits alighted more frequently on vertical than horizontal traps, but shape and spectral reflectance were insignificant. However, when traps were spaced 0.25 m apart, females orienting to Pr2S2 baits alighted more frequently on cylinders than spheres. Mated females alighted more frequently on green than white cylinders, but unmated females responded to cylinders independent of spectral reflectance. When located 20 m downwind from Pr2S2 baits, mated females alighted on green cylinders significantly more often than unmated females. Response to traps mimicking onion plants suggests that ovipositional host‐finding in female onion flies is dominated by olfactory responses at long range (several metres) and by visual cues at short‐range (ca. 1 m). The view that host location by female onion flies is a hierarchical response pattern mediated by multiple sensory modalities and modified by resource level (habitat) and reproductive status, is discussed.

“…As shown in Figure 1, UV white reflects high levels of all wavelengths of the insect spectrum between 350 and 650 nm. Females of D. radicum and D. antiqua have been shown to occupy the lower regions, and males the upper regions of cabbage (Tuttle et al 1988) and onion fields (Vernon et al 1989). wavelengths longer than 550 nm) had occurred, which could have resulted in the UV white traps appearing "UV blue" to male D. platura.…”

The Canadlan Entomologzst 128: 1077-1085 (1996) The responses of adult cabbage maggot [ D~l i a radic*vm (L.)], turnip maggot [D.f7oralis (Fallen)], radish maggot [D. platripalpis (Stein)], and seedcorn maggot [D. platura (Meigen)] to sticky tnps painted blue, yellow. green. non-UV-reilecting white, or W-reflecting wh~te, were determined in a field of canola (Bmssira rapa cv. Tobin) at the rosette and flowering stages. Traps colored white. Mue. or yellow generally caught higher numbers of D. radicrcm. D.floralis. and D. plrnripalpis than did traps colored green ~;uv-reflecting white. ~ependi& on the crop devc~d~menta~ s t a g and its background color. resuonse to color sometimes differed both within and between the sexes. This was most pronounced for D.Jor~11is. for wluch blue and white t~aps were preferred by males at the rosette stage but not the flowering stag. and for which white. but not blue, traps were preferred by females at the rosette stage. White and blue, but not yellow, were the colors preferred by male and female D. plurura in our study. with W-reilecting white also being preferred by males during the flowering stage. It was observed that catches on white and yellow traps were often significantly different, and that white versus yellow preferences could be reversed within or between males and females of certain species during the rosette w flowering stapes. The data suggest that the concurrent use of' white and yellow sticky traps should he considered when conducting relative abundance surveys of Delia spp. in canola fields. Vernon, R.S., et J.S.
