Contrary to general belief, larvae of Ancylostoma duodenale do not always develop directly to adulthood upon invasion of man. In West Bengal, India, arrested development appears to be a seasonal phenomenon which results in (i) reduction of egg output wasted in seeding an inhospitable environment and (ii) a marked increase in eggs entering the environment just before the monsoon begins.
与一般看法相反，十二指肠钩口线虫幼虫侵入人体后并非总是直接发育为成虫。在印度西孟加拉邦，发育停滞似乎是一种季节性现象，其结果是：（i）减少了在不适宜生存环境中产卵所造成的浪费；（ii）在季风开始前进入环境的虫卵显著增加。
