Family Simuliidae Genus Simulium
48
Prevention and Control of Nematoceran (Medicine given)

58
Do all larvae instars feed in Tabanid flies
No, Stage 1 & 2 do not feed Stage 3 and onwards feed and are carnivorous
59

-DEET: diethyltoluamide -zebra stripes
60
Genus under Family Tabanidae
- Tabanus - Chrysops - Haematopota
61
How do horseflies locate their prey?
Through movement, warmth and the CO2 it breaths out.
62
Where do Haematopota usually bites
around the ankles since they tend to fly low
63
Where do Tabanus usually bite
they buzz loudly bite ankles, legs or back of the knees
