Article body

[edit]

The current wikipedia article states - Allantonematid nematodes infect insect larvae by piercing through the cuticle, after which they reside in the insect blood. There they develop through multiple juvenile stages before being shed out the anus or reproductive tracts. Mating typically occurs external to the insect host, after which mated female nematodes infect new hosts.

Agricultural Impacts

[edit]

Thripinema fuscum

[edit]
Thrips impact on awa.

Thripinema fuscum is a Allantonematidae nematode that, can naturally decrease the population of Frankliniella fusca, Tobacco thrips.[1] Commonly found in Florida, T. fuscum that infect tobacco thrips have been shown to only affect the reproduction system of the thrips, causing a decrease in thrips over time.[1] Infertility of F. fusca is caused by damage to ovarioles and loss of eggs when infected by T. fuscum.[1] The life cycle of the T. fuscum from infection to the adult life stage is around 9 days in the F. fusca.[2] The infectious nematode lives primarily in the hemocoel of the thrips.[2]

Parasitylenchus bifurcatus

[edit]

Parasitylenchus bifurcatus parasitizes Harmonia axyridis, a beetle introduced to Europe from central and South Asia.[3] H. axyridis affects agricultural crops such as apples, pears, and grapes resulting in reduced quality of products made from these crops.[3][4] Both male and female H. axyridis can be infected by P. bifurcatus.[3] P. bifurcatus reproduces multiple times within one host, creating multiple generations.[3]

First generation P. bifurcatus female.[3]

The P. bifurcatus use bodily resources of the H. axyridis, such as fat deposits.[3] The reproductive system of H. axyridis may also be used for reproduction of P. bifurcatus, thus reducing the hosts reproductive organs.[3] Infected H. axyridis put under stress have been shown to die faster than uninfected H. axyridis in the same conditions, increasing the potential to use P. bifurcatus as natural biological control agents.[3][4]
