## Abstract Eight novel neonicotinoid analogues 1‐(2‐tetrahydrofurfuryl)‐5‐substituted‐1,3,5‐hexahydrotriazine‐2‐__N__‐nitroimines **3a**–**3h** were synthesized, and their structures were characterized by ^1^H NMR, IR and elemental analysis. The stereostructure of **3a** was determined by the sing
## 3 Results The values (24 h) of dimethyl-and di-allyl-LD 50 thiosuünate were comparable, varying from 0.02 mg litre~1 against P. interpunctella to 0.25 mg litre~1 against C. maculatus, although those for thiosulünates were generally lower than those for disulüdes. In comparison, 24-h values for
