A method for studying the life history parameters of Macrolophus pygmaeus Rambur was developed and described. Fecundity of the predator was studied by placing one female and one male in a plastic cylinder in which a stem piece was used as an ovipositional substrate. Smaller cylinders were used to study the percentage of egg hatch of M. pygmaeus. Results demonstrated that this method is suitable for studying the fecundity and egg eclosion of M. pygmaeus. Allowing for easy modification, the method offers suitable conditions for maintenance of both insect and plant material and can be inexpensively modified for different experiments and the parts are easily constructed. The proposed method could also be employed for similar studies on other predatory hemipterans such as mirids and anthocorids and very likely on other phytophagous insect species that lay their eggs in or on plant stems.
