| description | Dengue mosquitoes are evolving into a broader global public health menace, with relentless outbreaks and the rise
in number of Zika virus disease cases as reminders of the continued hazard associated with Aedes vectors. The use of chemical
insecticidesthe principal strategy against mosquito vectorshas been greatly impeded due to the development of insecticide
resistance and the shrinking spectrum of effective agents. Therefore, there is a pressing need for new chemistries for vector
control. Tea contains hundreds of chemicals, and its waste, which has become a growing global environmental problem, is almost
as rich in toxicants as green leaves. This paper presents the toxic and sublethal effects of different crude extracts of tea on Aedes
albopictus. The survival rates of larvae exposed to tea extracts, especially fresh tea extract (FTE), were markedly lower than those
in the control treatment group. In addition to this immediate toxicity against different developmental stages, the extracts tested
caused a broad range of sublethal effects. The developmental time was clearly longer in containers with tea, especially in those
with young larvae (YL) and FTE. Among the survivors, pupation success was reduced in containers with tea, which also
produced low adult emergence rates with increasing tea concentration. The production of eggs tended to be reduced in females
derived from the tea treatment groups. These indirect effects of tea extracts on Ae. albopictus exhibited different patterns
according to the exposed larval stage. Taken together, these findings indicate that tea and its waste affect most key components of
Ae. albopictus vectorial capacity and may be useful for dengue control. Reusing tea waste in vector control could also be a practical
solution to the problems associated with its pollution. |
