Sublethal toxicity of two insect growth regulators on Habrobracon hebetor (Hymenoptera: Braconidae) under laboratory conditions

The sublethal effects of lufenuron and lufenuron?+?fenoxycarb were tested on the adult stage of the parasitoid wasp Habrobracon hebetor under laboratory conditions. Bioassay tests were carried out in the incubator at a temperature of 26?±?1?°C, relative humidity of 65?±?10% and photoperiod of 16:8 (L:D). Exposure cages were used for the experiments. Tests were conducted in three replications. Young female wasps were exposed to the residues of the pesticides’ sublethal concentrations (LC₂₅) after 1, 24, 48 and 72 h, and then their mortalities were recorded. Results showed that both insecticide treatments had significant differences compared to the control, but not between themselves (df?=?1, F?=?29.21, α?<?.0001). It was also revealed that the time between insecticides application and H. hebetor release would significantly affect the survival of searching parasitoids (df?=?3, F?=?237.01, α?<?.0001). In this regard, the releasing programme should be postponed for at least 24 h after using these insect growth regulators.
