“…Likewise, other dipteran pests are known to be attracted to black colours such as the bluebottle fly, Calliphora vomitoria [29] and the tabanid fly, Tabanus illotus [36]. The preference for black surfaces found in water-living insects [37] and tabanid flies is associated with the perception of horizontally polarized light reflected from shiny surfaces such as water which is optimally seen at black targets [38].…”

“…For example, the whitefly, Bemisia tabaci , some tephritid flies, and anthomyid flies, Strobilomyia spp. are particularly attracted by yellow sticky traps [26–28], whereas the blue blowfly, Calliphora vomitoria, exhibits an innate colour preference for black [29] and fungus gnat, Bradysia difformis , significant preferred black surface rather than yellow LEDs [30]. Actually, in field experiments with coloured sticky traps chive gnat has already been successfully captured [31], but the quantitative analysis of the contribution of colour parameters such as hue and brightness to lure chive gnats has never been concerned so far.…”

High innate preference of black substrate in the chive gnat, Bradysia odoriphaga (Diptera: Sciaridae)

The chive gnat, Bradysia odoriphaga , is a notorious pest of Allium species in China. Colour trapping is an established method for monitoring and control of Bradysia species. In order to clarify the effect of colour preference of B . odoriphaga for the perched substrate, multiple-choice tests were used to assess the response of the chive gnat to different colour hues and brightness levels under different intensities of white illumination and two spectrally different illuminations. Given the choice among four colours differing in hue under different intensities of white illumination and two spectrally different illuminations, chive gnat adults significant preferred the black substrate, a lesser preference to brown and green substrates, and the least preference to orange substrate irrespective of illumination. Given the choice among four levels of brightness under the same illumination conditions as those in the previous experiment (different intensities of white illumination and two spectrally different illuminations), chive gnats preferred black substrate over dark grey, light grey and white substrates. Meanwhile, both virgin and mated adults significantly preferred black over other colour hues and brightness. Based on our results, we conclude that the chive gnat adults significantly prefer black substrates irrespective of colour hues and brightness. This behaviour does not alter with ambient light condition changes. No difference observed between choices of female and male adults. Our results provide new insight for understanding the colour choice behaviour in chive gnat and pave a way to improve monitoring and control of chive gnats and management.

This behaviour maintained the ambient 22 lights change. 23 24 25 26 27 High innate preference for black substrate in the chive gnat, Bradysia odoriphaga 28 (Diptera: Sciaridae) 29 Summary 30 The chive gnat, Bradysia odoriphaga, is a notorious pest of Allium species in China. Colour trapping is an 31 established method for monitoring and controlling of Bradysia species. In order to clarify the effect of 32 colour preference of B. odoriphaga for the egg-laying substrate, multiple-choice tests were employed to 33 assess the spontaneous response of the chive gnat to different colour hues and brightness levels under 34 different intensities of white illumination and two spectrally different illuminations. Given the choice 35 among four colours differing in hue under different intensities of white illumination and two spectrally 36 different illuminations, chive gnat adults visited preferably the black substrate, a lesser extent to brown and 37 green substrates, and the least extent to orange substrate irrespective of illumination. Given the choice 38 among four levels of brightness under the same illumination conditions as those in the previous experiment 39 (different intensities of white illumination and two spectrally different illuminations), chive gnats preferred 40 black substrate over dark grey, and these over light grey and white substrates. Meanwhile, both virgin and 41 copulated adults significantly preferred black over other colour hues and brightness. Based on our results, 42 we conclude that the chive gnat adults significantly prefer black substrates irrespective of colour hues and 43 brightness. This behaviour does not alter due to ambient light condition changes. No difference observed 44 between choices of female and male adults. Our results provide new insight for understanding the colour 45 choice behaviour in chive gnat and pave a way to improve monitoring and control of chive gnats and 46 management. 47 48 Key words: Bradysia odoriphaga, chive gnat, colour preference, black substrate, hue, brightness, colour 49 trapping. 50 259 An L. et al. 2018.
