Hypothesis
The survival of immature Anopheles arabiensis is influenced by rice agronomic activities and habitat conditions.
Conclusion
The survival of An. arabiensis immatures was better during the tillering stage of rice growth.
Supporting Evidence
- A total of 4,956 An. arabiensis immatures were collected in 1,400 dips throughout the sampling period.
- The overall survivorship from L1 to adult emergence was 69.4%.
- The mortality rate during the transplanting was 99.9% and at tillering was 96.6%.
- The study found significant variation in immature stage composition for each day's collection in each paddy.
Takeaway
This study found that baby mosquitoes called Anopheles arabiensis do better in rice fields when the rice plants are at a certain growth stage called tillering.
Methodology
The study used horizontal and vertical life tables to assess the survival of An. arabiensis in rice paddies.
Limitations
The study did not quantify the relative contribution of predation to larval mortality.
