ABSTRACT

Antennal sensilla include sensilla trichodea [a and b], sensilla chaeticaand sensilla coeloconica. Proboscis sensilla include the apical region bearssensilla chaetica at its apex and rasp-like structure along its length, whilethe distal region bears two types of sensilla styloconica, among which arefound sensilla trichodea and sensilla chaetica. Tarsal sensilla include onetype of sensilla in the form of curved sensilla trichodea [b] on the differenttarsal segments and the pulvilli, that bear various sensilla includingmacrotrichodea, sensilla chaetica and chemoreceptor setae. The ovipositorlobes include bear sensilla in the form of sensilla trichodea [a and b] and 5-6macrotrichodea. The male copulatory organs [represented by two harps andanal papillae] bear different receptors in the form of sensilla trichodea [a],swelling sensilla trichodea and pheromonal receptor or peg sensilla on the twoharps, as well as numerous numbers of sensilla styloconica on the two analpapillae
