Carbaryl kills both targeted (e.g., malaria-carrying mosquitos) and beneficial insects (e.g., honeybees), as well as crustaceans. [8] Because it is highly toxic to zooplankton, the algae they feed on experience blooms. Boone & Bridges 2003 find that larger algae eaters such as Bufo woodhousii benefit from this effect. [9]

Sevin, (b) Sevin XLR Carbamate: High risk to bees foraging even 10 hours after spraying; 3 – 7 days (b) 8 hours @ 1.5 lb/acre (1681 g/Ha) or less. Bees poisoned with carbaryl can take 2–3 days to die, appearing inactive as if cold. Sevin should never be sprayed on flowering crops, especially if bees are active and the crop requires pollination.

Entomophaga grylli is a fungal pathogen which infects and kills grasshoppers.It is the causal agent of one of the most widespread diseases affecting grasshoppers. This is sometimes known as summit disease because infected insects climb to the upper part of a plant and grip the tip of the stem as they die; this ensures widespread dispersal of the fungal spores. [1]
There are two types of pyrethroids: those with and without α-cyanogroup. The neurotoxicity of bifenthrin is based on the affinity to the voltage-gated sodium channels (in insects as well as mammals). The pyrethroids with an α-cyanogroup block the sodium-channel permanently, causing the membrane to be permanently hyperpolarized.
