Abstract:

To investigate the effects of four insecticides (diflubenzuron, dinotefuran, beta-cypermethrin and chlorantraniliprole) on the mycelia growth and fruiting body development of Pleurotus pulmonarius and Auricularia cornea, two application methods(substrate mixing and spraying) were employed. Residue analysis was also conducted by using liquid chromatography-tandem mass spectrometry (LC-MS/MS) and gas chromatography (GC). It was shown that the substrate mixing with 1 000 mg·L-1 chlorantraniliprole exhibited the highest inhibition rate on mycelia growth of P. pulmonarius, which was significantly (p<0.05) higher than the other treatments. The substrate mixing with 1 000 mg·L-1 beta-cypermethrin and chlorantraniliprole exhibited the highest inhibition rate on mycelia growth of A. polytricha, which was significantly higher than the other treatments. Under substrate mixing: 100 mg·L-1 beta-cypermethrin exhibited the least impact on the yield of P. pulmonarius fruiting body, with a bioconversion rate exceeding 48% for the first flush; 100 mg·L-1 dinotefuran showed the least impact on the yield of A. cornea fruiting body with a bioconversion rate over 64%. Under insecticides spraying: dinotefuran caused no significant yield reduction in P. pulmonarius fruiting body, with bioconversion rates above 47%; 100 mg·L-1 dinotefuran and beta-cypermethrin demonstrated the minimal effect on the yield of A. cornea fruiting body, with bioconversion rates exceeding 64%. Insecticides residue content in fruiting body of P. pulmonarius and A. cornea was below the detection limit (0.01 mg·kg-1) with 100, 500 mg·L-1 beta-cypermethrin or chlorantraniliprole via substrate mixing. For insecticides spraying, the insecticides residue content in fruiting body of P. pulmonarius was within the maximum residue limits (MRLs) for the 4 insecticides at 100-1 000 mg·L-1. However, only when these insecticides were sprayed at 100 mg·L-1, the insecticides residue content in A. cornea fruiting body was within MRLs. Given the food security and disease control: spraying of 100-1 000 mg·L-1 dinotefuran or substrate mixing with 100-500 mg·L-1 beta-cypermethrin was optimal for P. pulmonarius; sparying of 100 mg·L-1 dinotefuran, beta-cypermethrin or substrate mixing with 100-500 mg·L-1 dinotefuran was acceptable for A. cornea.
