摘 要 ：本文用不同松树松针饲养马尾松毛虫,其结果与松针内含物的关系,经计算得出累计死亡率、化蛹率、羽化率、每个雌虫平均产卵率、周限增长率以及硬脂酸、油酸等14种。同时得出:维生素B₆(x₍₁₃₎)对马尾松毛虫的化蛹、羽化和周限增长率的影响是第一位的重要因素,低沸点物质(x₈)包括萜烯类物质是影响马尾松毛虫化蛹、羽化的第二因子,苏氨酸(x₍₂₁₎)是第三个因子。异亮氨酸(x₍₂₂₎)是影响马尾松毛虫产卵量的第一重要因子,蛋氨酸(x₍₂₀₎)是第二重要因子,维生素B₆是第三个重要因子。

Abstract:Experiments wero conducted in which the needles from different kinds of pine trees were used to feed Masson pine caterpillars in order to study the effects of the chemical components in pine needles on the growth of the insect. The regression models are obtained through statistic analysis:y₁=74.9716-5.92369x₍₁₂₎; y₂=82.205-6.11941x₍₁₂₎-15.124x₍₁₈₎+32.7815x₍₂₂₎; y₃=146.785-11.2636x₂+13.425x₄+2.50619x₅+1.98716x₆-3.04045x₃-95.1154x₍₁₃₎; y₄=143.858-4.87883x₂-0.596458x₃+12.8221x₄-3.06847x₃-88.6311x₍₁₃₎+9.19294x₍₁₄₎+0.44275x₍₁₅₎; y₅=-67.7002+3.64222x₆+85.575x₍₁₃₎-11.4652x₍₂₁₎; y₆=-64.5757+3.50711x₈+80.8537x₍₁₃₎-10.93x₍₂₁₎; y₇=117.775+127.237x₍₁₃₎-13.6729x₍₂₀₎-108.387x₍₂₂₎+26.7597x₍₂₄₎; y₈=-46.6297+122.538x₍₁₃₎ 87.2382x₍₁₆₎.In addition, another two results are obtained:1. Three components have important effects on the pupation, emergence and periodic growth rate of the insect. Vitamine B₆ is the most important factor, the substance of low boiling-point the next and threonine the last.2. Three components have important effects on the oviposition of the insect. Isoleucine is the most important factor, methionine the next and vitamine B₆ the last.
