A note on the effect of a blood meal on infective larvae of Wuchereria bancrofti in Culex fatigans

In two previous papers (Dissanaike et al., 1957a and 1957b) we described the technique of tagging Culex fatigans and Armigeres subalbatus (=obturbans) with P32 to obtain high beta activities. Filarial larvae were made to develop to the infective stage in these activated mosquitoes and were found to have beta activities high enough for detection individually.

1. Anopheles amictus in North Queensland is a favourable intermediate host for Wuchereria bancrofti, comparable but perhaps not quite equal to Culex fatigans. The two described varieties of A. amictus were both tested.2. Experiments with Aëdes vigilax and Culex sitiens show that the former is a rather poor host and the latter a very poor one though infective larvae develop in some mosquitoes.3. In experiments with Aëdes argenteus none of the sixty-two mosquitoes used proved hospitable.4. Some observations on the transmission of filariasis in New Britain and on mosquitoes there are mentioned.

Blood Meals

From January to July 1938, experiments with Anopheles maculipennis race atroparvus, Van Thiel, were undertaken to discover whether humidity and the age at which the females fed influenced their longevity. It was found that they lived longer at higher than at lower humidities; that most of the females which fed did so in the first three days; that those which fed on the second day after emergence lived longer than those which fed at other ages; and that the feeding period was slightly extended in the later experiments, though only a small proportion lived long enough to take their first blood meals on the fourth and fifth days.Rather more than 50 per cent. of each batch of newly emerged adults were females.A large proportion of the deaths of unfed males and females occurred during the first three days, most of them on the second day; this mortality decreased in successive experiments.Culex fatigans, Wied., behaved similarly.

1. There is a slow but definite loss of infective forms of B. pahangi from A. togoi maintained on honey and water alone and denied access to a host.2. During the first blood meal after maturation of the filarial larvae there is a highly significant loss of infective forms from the mosquitos. On the 13th day, when they concentrate in the head of the mosquito, there is an unusually high (96·2%) loss after bloodfeeding.3. The infective larvae migrate to and from the head and proboscis, and the thorax. There is also a migration to and from the head and the proboscis. This shows itself as a rhythm with 8 day oscillations.
