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.

The freezing process is usually initiated extracellularly in the gut, tissues, or hemolymph. In order to supercool to lower temperatures, freeze-avoidant insects will remove or inactivate ice-nucleating agents (INAs) such as food particles, dust particles, and bacteria, found in the gut or intracellular compartments of these organisms.
Metarhizium acridum [1] is the new name given to a group of fungal isolates that are known to be virulent and specific to the Acrididea (grasshoppers). Previously, this species has had variety status in Metarhizium anisopliae (var. acridum [2]); before that, reference had been made to M. flavoviride or Metarhizium sp. [3] describing an "apparently homologous and distinctive group" of isolates ...

The agriculture and forestry industries use insect pheromones commercially in pest control using insect traps to prevent egg laying and in practicing the mating disruption. It is expected that insect pheromones can also contribute in this way to the control of insect-borne infectious diseases such as malaria, dengue fever or African ...
