用食蟹猴疟原虫Ｂ株早期环状体接种１只恒河猴，接种后第２－１２天（血内仅存在１群原虫）测试了由第１－４代裂殖子形成的４代配子体（Ｇ）对大劣按蚊（海南株）感染性的活力周期。结果表明第１－４代裂殖子均形成了一定数量的Ｇ，由裂殖子发育到Ｇ功能成熟（可使蚊感染）各代有差异，第２代Ｇ至少需５５±１ｈ，第３代Ｇ则需６５±１ｈ；发育至７２±４ｈ时活力最旺，Ｇ寿命长者可达１００ｈ；生活期（对蚊有感染力的时间）第１、２代Ｇ约为１２－４２ｈ，第３代Ｇ约为１０－１９ｈ。Ｇ密度与蚊胃卵囊均数不成正比，第１、２代Ｇ对蚊的感染性比第３、４代强
One rhesus macaque was inoculated with the early annular body of Plasmodium malayi B strain and the 4th generation formed by the 1-4 generation merozoites was tested on day 2-12 (1 protozoal in blood only) Gametophyte (G) Anopheles dirus (Hainan strain) infectivity cycle. The results showed that all the 1-4 generation merozoites formed a certain number of G, from the development of merozoites to G functionally mature (mosquito infection) generation differences, the second generation G at least 55 ± 1h, the first 3 Generation G is 65 ± 1h; when developed to 72 ± 4h, the most vigorous activity, G life expectancy of up to 100h; life (mosquito-infective time) first and second generation G is about 12-42h, 3 generations G is about 10-19h. G density is not proportional to the average number of mosquito oocysts, the first and second generation G mosquito infectivity than the third and fourth generation
