Term
|
Definition
| Insecticides which inhibit AChR in insect CNS, resulting in flaccid paralysis and death |
|
|
Term
|
Definition
Insecticides which cause prolonged opening of voltage-dependent Na+ channels and so prolonged depolarised after potential - hypersensitive so whole system locks up
e.g. permethrin, cypermethrin |

Insecticide which blocks octopamin R (the vertebrae equivalent of noradrenaline) - results in CNS hypersensitivity
-contraindicated in horses
e.g. amitraz |

Term
|
Definition
An insecticide - GABA-R antagonists i.e. inhibits neuronal inhibition and hyperpolarises cell membrane - hyperexcitation in CNS and PNS resulting in convulsions and death
NB: fibronil = frontline |

Term
| Juvenile Hormone Analogues |
|
Definition
A class of insect growth regulator / insecticide - analogues cause development of abnormal pupae ad prevent emergence of viable adults (normal hormones prevent metamorphosis until larve is fully grown)
e.g. Methoprene |

Term
| Chitin synthesis inhibitors |
|
Definition
Class of insect growth regulator / insecticide - drugs inhibit the enzymes which synthesise chitin (forms support elements in exoskeleton) - affects developing offspring rather than adults
Benzyl ureas e.g. lufenuron (Program) |
