However, insect-originating reoviruses have not been reported in orthopteran insects. Infected pupae are frequently reduced in size and the majority of diseased adults are malformed. Larvae of Uranotaenia sapphirina stop feeding as early as 4 days post-infection with cypovirus, resulting in chronic diarrhea and the loss of body size and weight. Diadromus pulchellus idnoreovirus 1 plays a role in helping determine the sex and ploidy of the host. Drosophila S virus is related to the S phenotype in Drosophila simulans. Reovirus infections can produce chronic disease in Lepidoptera and Hymenoptera and significantly alter the life history traits of the hosts.

Insect-related reoviruses are classified into genera Cypovirus, Idnoreovirus, Dinovernavirus, and Fijivirus. Members of the Reoviridae have a wide host range, including invertebrates, vertebrates, plants, fungi, and protists. Ninety-seven species of Reoviridae are divided into fifteen genera. Reoviridae is a family of double-stranded RNA (dsRNA) viruses with 9–12 linear genome segments. Recently, our study using a metagenomic approach revealed that grasshoppers harbor an enormous diversity of DNA and RNA viruses. To date, only Melanoplus sanguinipes entomopoxvirus have been used as a microbial insecticide, and a picornavirus in Schistocerca americana have been discovered. Another promising control method is using entomopathogenic viruses, which usually spread horizontally and transmit vertically in grasshopper populations. acridum has also been used in East Africa against recent desert locust infestations and used operationally against the migratory locust in East Timor and against red locusts in East Africa. Biopesticides such as Metarhizium acridum and Paranosema locustae have been used in the concerted controlling of grasshoppers in China and have successfully prevented migratory locusts from reaching plague proportions. In recent years, alternative biological control methods have been proven effective. Traditional grasshopper control relies on chemical pesticides, but it is later restricted because of its accumulation in the food chain and its persistence in the environment.

Grasshoppers (Orthoptera: Acridoidea) are herbivorous and polyphagous, with many species occasionally causing devastating threats to crops and pastures.
