Intervention Recommendations

Biology-driven action plans based on environmental conditions and risk levels

Select Scenario

Temperature

28°C

Humidity

65%

Rainfall

15mm

Risk Level

low

Biological Larvicide (Bti)

urgent

Apply Bacillus thuringiensis israelensis to breeding sites

85% effective

⏱️ Apply within 3 days before larvae mature to pupae

Biological basis: Bti produces toxins that specifically target mosquito larvae midgut, disrupting their digestive system before they can develop into adults.

Breeding Site Elimination

high

Remove standing water and treat permanent water sources

70% effective

⏱️ Immediately after rainfall events

Biological basis: Female Aedes mosquitoes require standing water for 7-10 days to complete larval development. Eliminating water breaks the lifecycle.

Targeted Adulticiding

medium

Ultra-low volume spraying during peak biting hours

60% effective

⏱️ Early morning (6-8 AM) or dusk (5-7 PM)

Biological basis: Aedes aegypti exhibits peak activity during dawn and dusk. Targeting these periods maximizes contact with adult mosquitoes.

Intensified Surveillance

medium

Deploy additional ovitraps and adult traps

40% effective

⏱️ Current conditions optimal for reproduction

Biological basis: 25-30°C is optimal temperature range for Aedes development. Increased surveillance during these conditions provides early warning.
