PROVING THE LARVAE OF THREE DIPTERAN SPECIES AS A FOOD FOR PREDATORY BUG PODISUS MACULIVENTRIS BREEDING
AbstractIn order to identify less expensive food source for the mass breeding of spined soldier bug, the larvae of three species of Dipteran insects were tested: the black soldier fly - Hermetia illucens L., the common green bottle fly - Lucilia sericata Meigen and the midge - Chironomus plumosus L.. We also undertook the comparison with the traditional food - caterpillars of the greater wax moth Galleria mellonella L. The experiments were carried out in two ways: feeding during the entire development cycle and only at the larval stage, i.e. to feed the nymphs, while the imago of the predator was fed with the caterpillars of G. mellonella. Comparison of a number of the development indicators and reproductive potential showed that the larvae of the midge and the black soldier fly are not suitable for the mass breeding of the spined soldier bug, because most indicators of the development and reproductive potential of the predatory bug are greatly decreased. The most acceptable option for replacing the G. mellonella caterpillars as alternative food is the larvae of the common green bottle fly. In this case the survival of nymphs and the lifespan of adults also decreases, but the duration of nymphs development slightly increases.
