Batkoa is a genus of fungi within the family of Entomophthoraceae and order Entomophthorales of the Zygomycota. [2] This has been supported by molecular phylogenetic analysis (Gryganskyi et al. 2012). [3]

Contents

The genus name of Batkoa is named by the American mycologist Richard A. Humber in 1989 to honor the Polish mycologist Andrzej Batko (1933-1997). [1]

The presence of rhizoids and having globose (rounded) rather than pear-shaped conidia helps identify Batkoa species from Entomophaga species. [4]

Description

The Hyphal bodies are elongated and walled (but not proto-plastic). The condiphores are simple with narrow 'neck' between the condium and condiogenous cell. The primary condia are globose and round, multi-nucleate, discharged by papillar eversion. The rhizoids (if present) are thicker than the vegetative hypae, with terminal discoid holdfast. The resting spores bud laterally from the parental cell. Unfixed nuclei have granular contents stained by aceto-orcein. [5]

Infection

Generally, when an insect (or host) comes in contact with Batkoa spores, they enter its body through leg joints or other chinks in its armor or through gaps in the 'skin'. The spores then start to multiply. As the fungi begin to overwhelm the insect, it stops eating, mating and crawls (or flies short distances) to a high, exposed place like on the side of a tree trunk or at the tip of a tall grass blade. There the fungus sends out threadlike hyphae from within the bug and attaching the insect to its perch, securely. The Batkoa fungus somehow triggers the host insect to open its wings fully, exposing its soft abdomen completely. That is the last time the host moves. Finally, the very small spores are expelled out from the insect’s belly, showering everything below with spores and potentially, 'powdered death'. [6]

Hosts

Batkoa major is known to infect the invasive spotted lanternfly (Lycorma delicatula) in north-eastern North America, [7] including Pennsylvania. [8] No other recorded insects have been killed by Batkoa major in the Pennsylvania area. [9] Batkoa major is also a host on the ptilodactylid beetle ( Ptilodactyla serricollis in Maine and North Carolina. [4] The pine beauty moth (Panolis flammea) in Scotland. [10] It was also found on aphid, Myzodium modestrum in Sweden (Gustafsson, 1965).

In June 2007, an epizootic was observed in a crane fly ( Tipula sp.) population in an area between Galugah to Bishehband in Mazandaran Province of Iran. The fungus was identified as Batkoa apiculata(Thaxter) Humber. [11] Batkoa apiculata has also been reported discovered on 3 species of aphid in France (Thoizon, 1970) and while in Poland, it was found on a wide range of insects (Balazy, 1993). [4] Baktoa apiculata has also been found on moth, Mentaxya muscosa (Lepidoptera, Noctuidae) in Africa. [12]

Various Batkoa species and also Furia species are being studied for the control of the (spittlebugs) cercopids Mahanarva fimbriolata and Deois schach which are known pests of sugarcane and pastures in Brazil. [13] [14]

Batkoa amrascaeS. Keller & Villac. (1997) infects the cotton leafhopper, Amrasca biguttula (Homoptera: Cicadellidae) in the Philippines. [15]

In Spain, Batkoa apiculata was found on Diptera Nematocera and Batkoa limoniae was found on Diptera Limoniidae. [16]

Distribution

It has been recorded being found mainly in North America and Great Britain, [17] with a few other recordings elsewhere. Such as parts of Europe; France, Poland, Sweden, [4] Spain, [16] Iran, [11] the Philippines, [15] and Brazil. [13] [14] Batkoa hydrophila, [18] and Batkoa gigantea has been recorded found in Switzerland. [19]

An entomopathogenic fungus is a fungus that can kill or seriously disable insects. They do not need to enter an insect's body through oral ingestion or intake; rather, they directly penetrate though the exoskeleton.

Metarhizium robertsii is a fungus that grows naturally in soils throughout the world and causes disease in various insects by acting as a parasitoid. It is a mitosporic fungus with asexual reproduction, which was formerly classified in the form class Hyphomycetes of the phylum Deuteromycota.

<span class="mw-page-title-main">Entomophthorales</span> Order of fungi

The Entomophthorales are an order of fungi that were previously classified in the class Zygomycetes. A new subdivision, Entomophthoromycotina, in 2007, was circumscribed for them.

<i>Entomophthora</i> Genus of fungi

Entomophthora is a fungal genus in the family Entomophthoraceae. Species in this genus are parasitic on flies and other two-winged insects. The genus was circumscribed by German physician Johann Baptist Georg Wolfgang Fresenius (1808–1866) in 1856.

<i>Entomophaga</i> (fungus) Genus of fungi

Entomophaga is a genus of entomopathogenic fungi in the Entomophthoraceae family and also the order Entomophthorales. This has been supported by molecular phylogenetic analysis.

<span class="mw-page-title-main">Entomophthoromycota</span> Division of fungi

Entomophthoromycota is a division of kingdom fungi. In 2007, it was placed at the taxonomic rank of subphylum in the most recent revision of the entire fungus kingdom. In 2012, it was raised to the rank of phylum as "Entomophthoromycota" in a scientific paper by Richard A. Humber 2012. Divided into three classes and six families, it contains over 250 species that are mostly arthropod pathogens or soil- and litter-borne saprobes.

The spotted lanternfly is a planthopper indigenous to parts of China and Vietnam. It has spread invasively to Japan, South Korea, and the United States. Its preferred host is tree of heaven, but it infests crops including soybean, grapes, stone fruits, and Malus spp. In its native habitat, L. delicatula populations are regulated by parasitic wasps.

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 fungus is a species complex with several different pathotypes, each one of which seems to be host-specific to different subfamilies of grasshoppers. The pathogen is being investigated for its possible use in biological pest control of grasshoppers.
