ABSTRACT

We describe the mating behavior of 4 species of Oxyinae: Oxya hyla hyla Serville, 1831, O. velox (Fabricius, 1787), O. fuscovittata (Marschall, 1836) and Oxyina bidentata Willemse. In trials carried out in laboratory we verified the following mating sequence: (1) sexual recognition by antennation; (2) courtship with male turning his abdomen towards the female performing mediolateral antennae vibration and jerking its body antero-posteriorly. We quantified elapsed time of each behavioral sequence i.e. age of maturation, duration of pre-copulatory and mating, interval between each mating, length of copulation, and number of mating in entire life of insect and also discussed its implications in the observed mating behavior. We examined that reproductive activity of Oxyinae was at its maximum in August to December. Mating duration has also been identified as a pest control method in which the insect does not become resistant.
