Neutral differential equations with variable sign coefficients are separated into neutral differential equations with positive and negative coefficients by transformation. According to the characteristic of these equations, a real number set with supremum is constructed, and sufficient conditions for oscillation of all solutions to neutral equations with variable sign coefficients are obtained.

To determine the role of neutral trehalase during storage stability of spores, we constructed a M.anisopliae RNAi transformant and an overexpression transformant. Analysis of these transformants revealed that the expression level of the neutral trehalase gene in RNAi transformant(No 688) was reduced to 50% of which found in wild type and the overexpression transformant(No 113) showed approximatlely 2-fold higher levels of neutral trehalase mRNA than that found in wild-type control.
