Article: Source, optimal dose concentration and longevity of trail pheromone in two Monomorium ants (Formicidae: Hymenoptera)[show abstract] [hide abstract]
ABSTRACT: Workers of Monomorium lepineyi and Monomorium bicolor secrete trail pheromones from their venom glands. The Dufour’s gland and the hind gut secretions have no effect on the trail pheromone activity in M. lepineyi, while in M. bicolor the secretions have an inhibitory effect. The optimal dose of the trail- following in each of the mentioned two species was found to be 1.0 and 0.1 poison gland equivalent/30 cm trail, respectively. Although the concentration of the optimal dose in the two species is different, the longevity of each is nearly the same as the pheromone lasts 120 min.Source, optimal dose concentration and longevity of trail pheromone in two Monomorium ants (Formicidae: Hymenoptera). 01/2010; 22:57/60.
Article: Trail communication in two Paratrechina species Paratrechina longicornis (Latreille) and Paratrechina vividula (Nylander, 1846) (Hymenoptera: Formicidae)[show abstract] [hide abstract]
ABSTRACT: The hind gut of the worker of the two Paratrechina species is the source of the trail pheromone. In P. vividula, the poison gland secretion has an inhibitory effect but in P. longicornis it hasn’t. In P. lon gicornis and P. vividula, the optimum dose of the trail- following was found to be 1 gaster equivalent / 30 cm trail. The optimum dose lasting time could last for 105 minutes in both the two species.Egyptian journal of Zoology. 01/2008; 51:449-459.
