Predatory abilities of Mononchoides longicaudatus and M. fortidens (Nematoda: Diplogasterida) and factors influencing predation

Abstract

The predatory abilities of Mononchoides longicaudatus and Mononchoides fortidens (Nematoda: Diplogasterida) and factors that influence the booty In in vitro studies examined the predatory skills of all stages of Mononchoides longicaudatus and M. fortidens, including prey capture, the mechanism of food intake, amount of prey making for adults and juveniles, as well as the influence of the number Beutebevorzugung prey, the predator hunger and temperature on the booty. The mechanisms of prey capture and feeding, are divided into five phases: the encounter with prey, attack response, attack, release saliva / extracorporeal digestion and food intake. Most phases were comparable for both predators. M. longicaudatus began fortidens frequently and needed less time to eat the prey than M.. The latter examined his booty and soft for a long time, during the examination of M. fortidens was intense and shorter. The rate of the prey was making in male and female robbers beyond twelve days away immediately. It was controlled by the number of available prey, the starvation of the predator, and temperature. The highest prey found in a population of 200 prey animals at 25-30 ° C instead of robbers who had been starving for 12 days. Acrobeloides sp. Cephalobus sp., Panagrellus redivivus and Meloidogyne incognita J2 stages of Anguina tritici and were preferred by two robbers at the most. Hoplolaimus indicus and Hemicriconemoides mangiferae were not eaten.
