Vitamin K1 added to a basic diet for the house cricket, Acheta domesticus (L.), significantly improves growth of male and female larvae. Growth is significantly better with 18.7 μg K1/g than it is with an equimolar amount of vitamin E. Unlike vitamin E, however, vitamin K1 is without effect on reproduction. Vitamins K3 and K5, and coumarin, have no effect or a slightly inhibiting effect on growth, and no effect on reproduction.
