Club circumference is divided equally by 6 trichodea Type I, arranged radially around the perimeter of each segment. Trichodea Type II and basiconica Type I occur on the entire receptor field of each club segment, while basiconica Type II and styloconica occur in bands along the distal edges of the dorsal surface of segments II and III, respectively. Basiconica Type III were found only at the extreme distal tip of the antennal club on segment IV. Significantly greater ( p = 0.05) numbers of sensilla trichodea Type II and basiconica Type II, found on the ventral surfaces of male and female antennal clubs, suggest that these sensilla are utilized in host reception during weevil antennal tapping.}, number={6}, journal={INTERNATIONAL JOURNAL OF INSECT MORPHOLOGY & EMBRYOLOGY}, author={SMITH, CM and FRAZIER, JL and COONS, LB and KNIGHT, WE}, year={1976}, pages={349–355} } @article{smith_frazier_knight_1976, title={ATTRACTION OF CLOVER HEAD WEEVIL, HYPERA MELES, TO FLOWER BUD VOLATILES OF SEVERAL SPECIES OF TRIFOLIUM}, volume={22}, ISSN={["0022-1910"]}, DOI={10.1016/0022-1910(76)90219-5}, abstractNote={Abstract Steam distilled volatiles from flower buds of white clover, Trifolium repens, attracted significantly greater numbers of female clover head weevils, Hypera meles, than males, in laboratory bioassays. Persian clover, T. resupinatum, bud extract, which attracted significantly more females than either small hop clover, T. dubium or red clover, T. pratense, also displayed qualitative and quantitative differences in the gas chromatographic profile of its bud volatiles. The strong attraction of normal females to Persian clover in laboratory bioassays was abolished by antennectomy, suggesting that attraction is regulated by olfactory receptors located on weevil antennal clubs. Weevils demonstrated a similar attraction to Persian clover in the field, indicating the possibility of developing a lure made from the flower bud extract of this clover to trap weevils for control or population monitoring purposes.}, number={11}, journal={JOURNAL OF INSECT PHYSIOLOGY}, author={SMITH, CM and FRAZIER, JL and KNIGHT, WE}, year={1976}, pages={1517–1521} }
