bugs and insecticide

true bugs taxonomy and examples

c. insecta o. hemiptera; bed bugs and triatomine bug

what is classification based off of?

mouthparts; suck the plant fluids or blood

monoculture risks

vast acreage of one type of crop plant; it has an increase of density of susceptible hosts and a major decrease of genetic diversity, where we see a negative frequency dependent selection

bed bug symptoms

not usually any signs, only can see and feel the bites when you’re allergic to them; DO of nymphs (incomplete metamorphosis) and adults in cracks and crevices and not currently vectors of any diseases

triatomine bug disease

important vector for T. cruzi, substandard housing and proximity to wildlife reservoirs are main risk factors

neonicotinoids

mimics micotine; acetylcholine agonists with a very low toxicity to vertebrates. imidacloprid is the most widely used insecticide and terrible for honey bees

non-toxic insecticides

boric acid (not for bed bugs) and DE, oil, IGRs or JH agonists

mechanisms of pesticide resistance

1. enzymatic destruction of compound

2. drug target mutates

3. increased clearance of drug

4. decreased penetrance of drug

5. behavioral changes
