A morphometric study on H. armigera antenna showed four styles of sensilla, i.e., styloconica, chaetica, coeloconia, and trichodea, and their numbers were estimated. Sensilla trichodea detect inter and intraspecific communication signals and was the most numerous. They were divided into three types: type 1, the longest, with a length of 34.04±3.16mm and about 2.16 to 2.42 mm in diameter at its base; 2) type II, intermediate, with a length of 7.62±0.4mm and a range in diameter similar to that of type II.
