1、trichodea Sensilla The sensilla trichodea were the most numerous sensilla on the antennae,being localized and distributed randomly on all subsegments S.trichodea were hair-shaped,angled about 45'to the antennal surface. They can be divided into two subtypes according to their length:Subtype I(82.19um in length)and Subtype II (39.81um in length),which were present in both males and females (Lepidoptera:Pyralidae) Subtype I is mainly present on male antennae Subtype II is mainly present on female antennae

Function: S.trichodea play a major role in sensing mechanical stimuli and in detecting chemical stimuli in insects S.trichodea have been shown to be the olfactory receptors responsible for detecting sex pheromones (host or mate location

2、chaetia sensilla Sensilla chaetica were straight,wide at the base,and blunt (rounded)at the distal end and arose from a distinctive round collar--like socket(自状窝) Sensilla chaetica present on each fagellar segment in both sexes,angle to the antennal surface is larger than S. trichodea about 60'-90
