Incidence of Snakebite in Four Townships of Yangon Region

The true incidence of snakebite in Myanmar is unknown. The current data are based on hospital returns to Ministry of Health and Sports and they are likely to be under-reported. A community-based survey is useful to know the current burden of snakebite and thus for planning and formulating str

TITLE:   Larvivorous potential of dragonfly nymphs.

ABSTRACT:   Predatory rates of naturally occurring dragonfly nymphs-Bradinopyga geminata (Rambur) (tank variety) and Crocothemis servilia (Drury) (pond variety) collected from local tanks and ponds were studied under laboratory condition in Health and Disease Control Unit, Mingaladon from January 2002 to 2003. The series of experiment included two to five replicates for different sizes of nymphs. The results showed that medium-sized B. geminata consumed 62 ± 22 Aedes aegypti larvae (third and fourth instars) per nymph per 24 hours and the same size C. servilia 53 ± 21 per 24 hours. When all instars and pupae (equal number of 40 each) were introduced, the predatory rates rose to 137 ± 14 per 24 hours and 128 ± 9 per 24 hours for these varieties respectively. Predatory rates of both varieties were found not to be statistically different (p> 0.05). Medium-sized nymphs consumed most Aedes larvae followed by large and small-sized (p<0.005). The predatory rates increased with increasing number of larvae and pupae introduced and they were well correlated (r = 0.97 – 1.0, p< 0.05). The nymphs consumed most first instar of Aedes larvae and progressively fewer of each of successive stage. The nymphs were also found to be superior to other predators on feeding rate. The study highlighted that due to their advantages and the facts of being locally available, harmless to human and high in predation rate, dragonfly nymphs should be used as bio-control agents in the field by augmentative release, monthly or as necessary, into major water-storage containers especially heavy and irremovable containers such as concrete tanks, concrete and metal drums and earthen glazed jars to suppress Aedes mosquito, thereby controlling dengue haemorrhagic fever effectively.
