本文报告了１９７３～１９９４年对山东中华按蚊传播间日疟的系统研究结果。在７０年代暴发流行期间感染率为０．４７％，病家蚊经饲养后解剖感染率为１３．２％；实验观察人工感染蚊虫感染率为３６．１％，其中腺子孢子阳性率为１７％，胃部囊合子阳性率为２３．３％；鲁东半岛疟疾非暴发流行区与鲁西南易暴发流行区中华按蚊对间日疟原虫的易感染性无显著性差异；间日疟原虫在中华按蚊体内发育的起点温度为１４．９℃，有效积温为１０５．１５℃；传播间日疟的媒介能量年内季节变化与年度变化均与发病情况较为一致。自１９８２年以来，其能量稳定地处在低水平。此结果提示，若无大量传染源输入，不会造成疟疾大流行。
This article reports the results of a systematic study of P. vivax between 1973 and 1994 in Anopheles sinensis. During the outbreak in the 1970s, the infection rate was 0.47%, and the infection rate of mosquitoes after infection was 13.2%. The infection rate of artificial infection was 36.1%, of which the positive rate of gonadal sporozoites was 17 %, The positive rate of gastric cystic zygotes was 23.3%; there was no significant difference in susceptibility to P. vivax between the malaria non-endemic area of Ludong Peninsula and Anopheles sinensis in the endemic area of south eastern Shandong; The onset temperature of Anopheles sinensis in vivo was 14.9 ℃ and the effective accumulated temperature was 105.15 ℃. The seasonal changes and annual changes of vector energy of P. vivax during the year were consistent with the incidence. Since 1982, its energy has been at a steady low level. This result suggests that there will be no malaria pandemic without a significant source of inputs.
