The life cycle of Acanthostomum burminis [Trematoda, Acanthostomidae]

Acta Parasitologica

1998

tom 43

nr 4

The life cycle of Acanthostomum burminis (Bhalerao, 1926) Bhalerao, 1936 (Trematoda, Acanthostomidae) infecting Xenochrophis piscator has been elucidated. Life cycle stages were successfully reared in the laboratory. The life cycle, from cercaria to adult, took more than two months to complete. Pleurolophocercous cercariae were found in the thiarid snail Thiara tuberculata. Metacercariae occurred in fin rays of several species of freshwater fishes. Snakes became infected when fed on fishes containing metacercariae. The prepatent period is 28 days. Successive stages in the development of metacercariae and adults were followed.

Effects of light and temperature on the emergence of Haplorchis pumilio cercariae from the snail host, Thiara tuberculata

tom 42

nr 1

The cercaria of Haplorchis pumilio exhibited diurnal pattern in the emergence from the snail host, with peak between 10 am and 12 noon and limited emergence during night. Continuous light permitted emergence to continue rhythmically while continuous dark has suppressed the emergence. Inversion of photoperiod has resulted in immediate reversal of the emergence pattern. Variation is found in the numbers of cercariae released by different individuals of snails and by the single snail on different days, but consistency is maintained in the emergence pattern. Temperature of 30-35°C is found to be favourable for the cercarial emergence. The results of the study demonstrate that emergence pattern is influenced by both exogenous and endogenous factors.
