Effects of different coffee extracts on the egg fertility and lifespan of dengue vectors (Aedes albopictus and Aedes aegypti) (diptera: culicidae)
This study was conducted to examine the impacts of various extracts of coffee on the egg production aedes fertility and adult lifespan in two dengue vectors. Coffee is known for its chemical richness that is so far no resistance in insects was documented. For this purpose, two types of extracts...

This study was conducted to examine the impacts of various
extracts of coffee on the egg production aedes fertility and adult
lifespan in two dengue vectors. Coffee is known for its chemical
richness that is so far no resistance in insects was documented.
For this purpose, two types of extracts (crude and used) from
two types of coffee (fresh and roasted) of Coffea canephora
(Robusta coffee) were used. We compared the effects of the
extracts on the egg hatching responses and the longevity of
dengue vectors; Aedes albopictus and Aedes aegypti. Overall,
the roasted coffee extracts tend to have more negative impact
than the fresh coffee extracts in reducing the hatching success.
Crude extracts of both fresh/green and roasted coffee seems to exerts more chemicals and appears to be more acidic than the
used extracts in which resulted in reduced rate of larval
eclosion. Longevity statistically has no difference among coffee
extracts However, based on the overall observation on the
longevity of the adult and the difference in the longevity
suggested that the exposure of the coffee to the dengue vectors
during the embryogenesis does reduces the longevity of the
survived adult by few days difference. |
