Using inbred laboratory stocks of the locust Schistocerca gregaria, two experiments were carried out using composite heat-treatment programmes of 40 degrees C and 30 degrees C combinations. These were designed to superimpose different heat-induced increases and decreases in chiasma frequency, to determine what interactions would occur and which effects might be dominant. It was found that both of the heat-induced decreases in chiasma frequency which can be obtained (Effects 2 and 3), were dominant over both of the different types of increase (Effects 1 and 4), with the largest decrease (Effect 3) being dominant over all others.
利用沙漠蝗（Schistocerca gregaria）的近交实验室种群，进行了两项实验，采用了40摄氏度和30摄氏度组合的复合热处理方案。这些方案旨在叠加不同热诱导的交叉频率增加和减少，以确定会发生何种相互作用以及哪些效应可能占主导地位。结果发现，可获得的两种热诱导交叉频率降低（效应2和效应3）均比两种不同类型的增加（效应1和效应4）占主导地位，其中最大的降低（效应3）比其他所有效应都占主导地位。
