Mating in most species of ants occurs during nuptial flights. In the African weaver ant, Oecophylla longinoda Latreille, mating has previously been hypothesized to take place within the nest before the nuptial flight. However, several researchers disagree with this supposition particularly with reference to the closely related species Oecopylla smaragdina (Fabricius) whose mating occur during nuptial flights. Understanding the mating strategy of O. longinoda is of importance for its successful application in biological control programs. We conducted field and screen house experiments during two mating seasons to determine whether the mating occur prior to the dispersal flight. We examined winged O. longinoda queens on the nest surface before taking flight, immediately after leaving the nest, up to twelve hours (12h) after leaving the nest and after settling naturally following the dispersal flights. Mating in captivity between different number of males and queens were also assessed. Only eggs produced by queens (N=65) collected after their natural settling hatched into larvae. No eggs hatched from any of the 527 winged queens that were collected prior to their dispersal flights and no mating attempts in captivity lead to viable offspring. Findings from the current study suggest that mating of O. longinoda queens take place during a nuptial flight and does not take place within the nest, as previously suggested.

Length Of Life

The life-history and bionomics of the Coreid bug, Theraptus sp., which causes premature nutfull of coconuts in Zanzibar, were studied in the laboratory and in the field.From the various experiments carried out it is concluded that:—The development of the insect from the egg to the adult took from 26–39½ days depending on temperature and the food available.The average length of life of the female is 45 days during which time she may produce over 100 fertile eggs.The primary host-plant of Theraptus is the coconut palm, but the bug readily infests mango, guava, cinnamon and cacao trees when they are fruiting.The pest will attack and develop successfully on nuts from the newly emerged to the mature ones.Agents which exert a measure of biological control include the tree-nesting ant, Oecophylla longinoda (Latr.), an internal Strepsipteran parasite, an unidentified Reduviid, two unidentified Hymenopterous egg-parasites and possibly some small ant species which prey on the eggs. Of these, only the ant, O. longinoda, is capable of giving complete protection to the palm which it occupies.
