Entomopathogenic nematodes (EPN) are a group of nematodes (thread worms), that cause death to insects. The term entomopathogenic has a Greek origin, with entomon, meaning insect, and pathogenic, which means causing disease. They are animals that occupy a bio control middle ground between microbial pathogens and predator/parasitoids.
A general life cycle of entomopathogenic nematodes. [2] Steinernema carpocapsae is categorized as an entomopathogenic nematode, which is a specialized subgroup of insect-parasitic nematodes. [3] [4] The infective juvenile stage (IJ) is a modified third stage larva and is the only free-living stage of this nematode. It is a developmentally ...
Commonly used nematode species to control pests on greenhouse crops include Steinernema feltiae for fungus gnats and western flower thrips, Steinernema carpocapsae used to control shore flies, Steinernema kraussei for control of black vine weevils, and Heterorhabditis bacteriophora to control beetle larvae.

It is known widely as a pest insect of stored food grain products such as flour , and of poultry-rearing facilities and it is a vector of many kinds of animal pathogens .
Boric acid is a weak acid, with pK a (the pH at which buffering is strongest because the free acid and borate ion are in equal concentrations) of 9.24 in pure water at 25 °C. But apparent p K a is substantially lower in swimming pool or ocean waters because of interactions with various other molecules in solution.
The lifecycle of this beetle includes pupation in the ground outside of the hive. Controls to prevent ants from climbing into the hive are believed to also be effective against the hive beetle. Several beekeepers are experimenting with the use of diatomaceous earth around the hive as a way to disrupt the beetle's lifecycle. The diatoms abrade ...
