Metaparasitylenchus hypothenemi (Nematoda: Allantonematidae) is a free-living nematode parasite that infects coffee berry borers (Hypothenemus hampei), small beetles that harm coffee crops worldwide. This nematode has been shown to interfere with the parasitic activity of the coffee berry borer by increasing the mortality of its progeny. [1]

Geographical distribution


M. hypothenemi has only been identified in coffee plantations in Chiapas, Mexico and Honduras. [2] Its only known host is the coffee berry borer (Hypothenemus hampei), which is originally native to Angola, Africa. [1] This raises the question of whether M. hypothenemi was brought over to the New World with the coffee berry borer or if it is native to Mexico and Central America and only found the coffee berry borer as a host when it was brought to the New World. [2]

In order to alleviate the economic burden the coffee berry borer has on the coffee cash crop, parasitoids of the borer have been used. Most notably Bethylid parasitoids, Eulophyd parasitoids (Eulophidae), and Braconid parasitoids (Braconidae) have been introduced in an attempt to reduce the beetle’s efficacy in destroying coffee plants. However, while these parasitoids improve the situation, they are not successful in eliminating the economic damage. Additionally, evidence suggests that the beetle is capable of developing resistance against the common pesticide endosulfan. [3] Therefore, use of Metaparasitylenchus hypothenemi to induce disease in borer populations has been considered.

It is prudent to explore such a course of action because use of the Metaparasitylenchus hypothenemi nematodes provides a method with which to sterilize female borers. Depending on how many parasitic females are present, sterilization can range from being partially derailed to being completely shut down. [1] Though sterilization fails to ward off a current generation of infection, by arresting the reproductive capabilities of these beetles the worm will ultimately curtail beetle infestation.

Loss of reproductive capabilities through Metaparasitylenchus hypothenemi parasitization is tied to the lifecycle of the nematode. Mature parasitic females are carried through the beetle’s lifecycle. During this time, eggs hatch within the female and proceed through to stage J3 (see Lifecycle) and at this point are ready to exit the host beetle. Exit occurs through the GI tract or the reproductive tract and expulsion involves arrest of the beetle’s own reproductive capabilities. [2]

Biological pest control Controlling pests using other organisms

Biological control or biocontrol is a method of controlling pests such as insects, mites, weeds and plant diseases using other organisms. It relies on predation, parasitism, herbivory, or other natural mechanisms, but typically also involves an active human management role. It can be an important component of integrated pest management (IPM) programs.

Parasitoid Organism that lives with host and kills it

In evolutionary ecology, a parasitoid is an organism that lives in close association with its host at the host's expense, eventually resulting in the death of the host. Parasitoidism is one of six major evolutionary strategies within parasitism, distinguished by the fatal prognosis for the host, which makes the strategy close to predation.

Root-knot nematode Genus of parasitic worms

Root-knot nematodes are plant-parasitic nematodes from the genus Meloidogyne. They exist in soil in areas with hot climates or short winters. About 2000 plants worldwide are susceptible to infection by root-knot nematodes and they cause approximately 5% of global crop loss. Root-knot nematode larvae infect plant roots, causing the development of root-knot galls that drain the plant's photosynthate and nutrients. Infection of young plants may be lethal, while infection of mature plants causes decreased yield.

Parasitoid wasp Group of wasps

Parasitoid wasps are a large group of hymenopteran superfamilies, with all but the wood wasps (Orussoidea) being in the wasp-waisted Apocrita. As parasitoids, they lay their eggs on or in the bodies of other arthropods, sooner or later causing the death of these hosts. Different species specialise in hosts from different insect orders, most often Lepidoptera, though some select beetles, flies, or bugs; the spider wasps (Pompilidae) exclusively attack spiders.

Coffee borer beetle Species of beetle

The coffee borer beetle or coffee berry borer is a small beetle native to Africa. It is among the most harmful pests to coffee crops across the world where coffee is cultivated. Spanish common names of the insect include barrenador del café, gorgojo del café, and broca del café.

Nematode A phylum of worms with tubular digestive systems with openings at both ends

The nematodes or roundworms constitute the phylum Nematoda, with plant-parasitic nematodes being known as eelworms. They are a diverse animal phylum inhabiting a broad range of environments. Taxonomically, they are classified along with insects and other moulting animals in the clade Ecdysozoa, and unlike flatworms, have tubular digestive systems with openings at both ends. Like tardigrades they have a reduced number of Hox genes, but as their sister phylum Nematomorpha has kept the ancestral protostome Hox genotype, it shows that the reduction has occurred within the nematode phylum.

<i>Xanthocryptus novozealandicus</i> Species of wasp

Xanthocryptus novozealandicus, the lemon tree borer parasite, is a wasp in the family Ichneumonidae. It is a native insect of New Zealand. It is also found in Australia and New Guinea. Females hunt for larvae of wood-boring beetles around March, including the lemon tree borer, a native cerambycid that tunnels into citrus trees, grapes and many native species. When a suitable host is found, the female pushes her ovipositor through the wood and injects her eggs into the grub. This has the incidental benefit of helping to control some pests. X. novozealandicus prefers to prey on second year lemon tree borer larvae. This specific parasite prefers to prey on larger second year larvae due to its larger size.

<i>Oemona hirta</i> Longicorn beetle native to New Zealand

The lemon tree borer, also known as the whistling beetle or the singing beetle, is a longhorn beetle endemic to New Zealand. Its larvae are generalist feeders, boring into the wood of a wide variety of trees, native and introduced. When citrus orchards were first established in New Zealand, this beetle started inflicting serious damage, and so gained the name "lemon tree borer". Four species within the genus Oemona have been identified, suggesting that more species could be found. When disturbed by predators or humans, the adult beetle stridulates creating a "rasp" or "squeak" sound by rubbing its thorax and head together against an area of thin ridges. Māori would eat a liquid called "pia manuka", which was produced by manuka trees when its wood was damaged by the larva. When Captain Cook first arrived in NZ, his naturalists, Banks and Solander, collected a lemon tree borer in their first collection between 1769-1771. This oldest collected specimen can be found in the British Museum. A few years after the first collection, the species would be first described by the Danish naturalist Fabricius in 1775.

Allantonematidae Family of roundworms

<i>Ips cembrae</i> Species of beetle

Ips cembrae, known generally as larch bark beetle or eight-toothed larch bark beetle, is a species of typical bark beetle in the family Curculionidae. Its habitat is Euro-Siberian, ranging from sea level to sub-alpine. It was first recorded in Great Britain in 1955. Populations were said to be found in Japan and China, but further research determined that those were actually Ips subelongatus.
