‘We still believe that for the purpose of obtaining a satisfactory supply of highly infected anopheles, it is best to allow the insects to feed on human blood only, but we have changed the view expressed in my former paper to the effect that feeding on certain fruits is inhibitory to oöcyst production. In our single feed experiments and for the carriage of anopheles from Italy and other countries [note: ‘Using the carrying-cages devised by Barraud (Indian Journal of Medical Research, Vol. xvii, No. 1, July, 1929, p. 281) we have received living batches of maculipennis and pseudopictus from Italy (sent by Professor Missiroli) culicifacies from India (sent by Mr.Baraud) and quadrimaculatus from the Mississippi (U.S.A.) sent by Dr. Mark Boyd.’] we allow the insects to feed upon raisins, and we have not found that this food is deleterious to zygote production and development. The following are the results of an experiment in which eight anopheles were fed on pulped apple for three days prior to being fed on a gamete carrier, and again on pulped apple each day thereafter until dissection. For control purposes eight of the same batch were fed on human blood only.’ (489)
