Article Title: Mating Procedures of Insects with Particular Reference to Neochetina Eichhorniae (Coleoptera: Curculionidae). A Biological-Control Agent of Water Hyacinth
by O. A. Oke

Studies on the mating procedures were made on virgin males and females of Neochetina eichhorniae. The virgin species of N. eichhorniae were raised from the stock of adult males and females N. eichhorniae reared in a plastic aquarium tank (100 cm x 100cm x 100 cm) containing water hyacinth plants on the premises of the Department of Zoology, University of Ibadan, Ibadan. Four pairs of virgin N. eichhorniae were placed inside an aerated covered vial (16.5 cm radius and 7.00 cm high) in the laboratory at a temperature range of 28-300c for observation. 5 trials were made. In each trial, a pair of weevils were placed together for one hour. A minimum copulation period of 60 seconds and maximum period of 120 seconds with a mean copulation period of 97.67 seconds was observed.
