目的：探讨不同血源对中华按蚊种群生殖、存活、传疟的影响。方法：在实验条件下，用人血、牛血、猪血、羊血分别饲养中华按蚊，观察记录中华按蚊吸血、产卵、孵化、寿命等方面的差异。结果：吸血量：吸猪血者最低，与其他3种血源比较差异有显著性(P0．05)。吸血率：吸牛、猪血者高，吸人、羊血者低；吸牛、猪血者与吸人、羊血者相比较差异有显著性(P0．05)。产卵量：吸牛血者最高，吸猪血者最低，差异有显著性(P0．05)。孵化率：吸牛血者最高，与其他3者比较差异有显著性(P0．05)。生殖营养周期：吸人血者最短，与吸牛、猪血者比较差异有显著性(PO．05)，吸牛、猪血者之间差异无显著性(P>0．05)。平均寿命：4种血源之间差异无显著性(P>0．05)。结论：证实中华按蚊为嗜吸畜血(牛、猪血)，兼吸人血的蚊种。中华按蚊种群与人的接触次数越多，传播疟疾的机率越大，提示多养猪作为生物屏障可减少防蚊不力地区疟疾的发生和流行。“,”Aim: To investigate the influence of different blood sources on population reproduction, survival, capacity of dis-ease-txansmission of Anopheles sinensis. Methods: Under the experimental conditions, Anopheles si.nensis was fed with humanblood and ox blood swine blood, and sheep blood, respectively. The differences of blood-sucking, oviposition, hatching and life-span ofAnopheles sinensis were observed. Restults: Anopheles sinensis fed with swine blood had the lowest quantity of bloed-suck-ing. There was significant difference between Anopheles sinensis fed with swine blood and those fed with other three kinds of blood(P 0.05). Anopheles sinensis fed with ox bloodand swine blood had the higher blood-sucking rate than that fed with human blood and sheep blood. There were significant differ-ences between the former two and the latter two ( P 0.05). Anopheles sinensis fed with ox blood had the highest quantity of oviposifion, and that fed with swine blood had the lowestquantity of oviposition, and there was high significant difference ( P 0.05). Anopheles sinensis fed with human blood had theshortest gonotrophic cycle, which was significantly different compared with that of those fed with ox blood and swine blood ( P 0.05). There were no significant differences among the mean life-spans four groups ( P >0.05). Conclusion: Anopheles sinensis is a kind of mosquito which like sucking blood of both hvestock and human. If populationof Anopheles sinensis has more oportunities to approach human, suggesting that the rate of malaria transmission may be high. Thelonger the life-span, the higher the potential of malaria transmission. Raising swine as biological barrier should be promoted in ar-eas with weak precautionary measures in order to reduce the prevalence of malaria.
