abstract: Sorghum midge, Stenodiplosis sorghicola (Coquillett), is one of
the most important pests of grain sorghum worldwide. Sorghum midge adults
emerge in the morning, mate at or near the site of emergence, and then the
females proceed in search of sorghum crop at flowering for oviposition, and
some visual and odor stimuli play an important role in host finding and oviposition
process. We used a glass apparatus with two (Y-tube) arms to study
the orientation of sorghum midge females to visual and odor stimuli under
laboratory conditions. Most sorghum midge females were attracted to yellow
(30%), followed by green (26%), red (23%), and blue (10%). Sorghum midge
females responded more quickly to yellow, followed by red, green, and blue.
However, under dual-choice conditions, differences in numbers of sorghum
midge females attracted to yellow versus green, red versus blue, and blue
versus green were not significant. More sorghum midge females were attracted
to sorghum panicle odors plus red (47%) or yellow (40%) colors than to host
odors alone (31%). Information on the color preference of sorghum midge females
could be exploited for developing suitable traps to monitor its abundance
in combination with kairomones or pheromones.
