History
The use of Entomopathogenic fungi in pest management covers a wide variety of Eumycota subdivisions. These subdivisions of Eumycota include; Mastigomycotina, Zygomycotina, Ascomycotina, and Deuteromycotina [1] In 1981, the first mycoinsectiside registered in the U.S. was Hirsutella thompsonii and was given the registered name; Mycar. This species has been noted to cause epizootics as early as 1920 in some species of spider mites [2]
With the rising cost of synthetic chemical pesticides and increasing cases of pesticide resistance, the search for natural biologically based forms of pest management has been a key area of research for the last decade. With the world population rising over 7 billion and the drastic effects of climate change, the need for alternative forms of pest control will become essential. Although insects are key in the performance of many ecosystems, they play a large role in the 35 billion dollars worth of crop that is lost in the United States each year [3]

my abstract
Processes (or mode of action??)
all invasive fungi use lytic enzymes like chitinase of glucan-1,3-B-glucosidases.
4 main steps of an attack:
- chemotaxi to that pest
- Recognition
- attachment
- degradation of host wall
Steps of an invasion
Necrotroph
Biotroph
pesticide preparation
Specific example
Trichoderma harzianum
Mycoparasitic Trichoderma viride as a biocontrol agent against Fusarium oxysporum f. sp. adzuki and Pythium arrhenomanes and as a growth promoter of soybean, Rojan P. Johna R.D. Tyagia, D. Prévostb, Satinder K. Brara, Stéphan Pouleurb, R.Y. Surampallic
Pythium`oligandrum
it is a water mould, but often they are studied as fungi and I have few reason why to put it in this cateroy
Gliocladium roseum
Biopesticides in Urban Environments
see main article: Fungi uses in Urban Environments
Entomopathogens are key components for integrated pest management solutions [4]. There is a large market for urban pest control that has been dominated by the use of pesticides and insecticides [4]. These chemical pesticides pose a danger not only to the person applying them, but other people, or pets, which may come into contact with the chemicals in an urban environment [4]. Previously used in agricultural settings as deterrents, fungi such as Beauveria bassiana, Metarhizium anisopliae and Paecilomyces fumosoroseus may have possible pest control applications in urban settings as well [5].
