Polyphagous Shot Hole Borer
''Euwallacea fornicatus'' is a species complex consisting of multiple cryptic species of ambrosia beetles (Coleoptera: Curculionidae: Scolytinae: Xyleborini), known as an invasive species in California, Israel and South Africa. The species has also been unintentionally introduced into exotic greenhouses in several European countries. As the rest of the ambrosia beetles, ''E. fornicatus'' larvae and adults feed on a symbiotic fungus ('' Fusarium euwallaceae'') carried in a specific structure called mycangium. In ''E. fornicatus'', the mycangium is located in the mandible. The combination of massive numbers of beetles with the symbiotic fungus kills trees, even though the fungus alone is a weak pathogen. ''Euwallacea fornicatus'' breeds in various live hosts and is considered a severe pest of several economically important plants, such as: tea (''Camellia sinensis''), avocado (''Persea americana''), citrus (''Citrus'' spp.) and cacao (''Theobroma cacao'').

Persea Americana
The avocado (''Persea americana'') is a medium-sized, evergreen tree in the laurel family (Lauraceae). It is native to Americas, the Americas and was first domesticated by Mesoamerica, Mesoamerican tribes more than 5,000 years ago. Pre-Columbian era, Then as now it was prized for its large and unusually Avocado oil, oily fruit. The tree likely originated in the highlands bridging south-central Mexico and Guatemala. Its fruit, sometimes also referred to as an alligator or avocado pear, is botanically a large Berry (botany), berry containing a single large seed. Avocado trees are partially Self-pollination, self-pollinating, and are often Plant propagation, propagated through grafting to maintain consistent fruit output. Avocados are presently cultivated in the Tropics, tropical and Mediterranean climates of many countries. Agriculture in Mexico, Mexico is the world's List of countries by avocado production, leading producer of avocados as of 2020, supplying nearly 30% of the glo ...

Pacific Islands
Collectively called the Pacific Islands, the islands in the Pacific Ocean are further categorized into three major island groups: Melanesia, Micronesia, and Polynesia. Depending on the context, the term ''Pacific Islands'' may refer to one of several different concepts: (1) those countries and islands with common Austronesian origins, (2) the islands once (or currently) colonized, or (3) the geographical region of Oceania. This list of islands in the Pacific Ocean is organized by archipelago or border, political boundary. In order to keep this list of moderate size, the more complete lists for countries with large numbers of small or uninhabited islands have been hyperlinked. Name ambiguity and groupings The umbrella term ''Pacific Islands'' has taken on several meanings. Sometimes it is used to refer only to the islands defined as lying within Oceania Oceania (, , ) is a region, geographical region that includes Australasia, Melanesia, Micronesia, and Polynesia.

Fusarium
''Fusarium'' is a large genus of filamentous fungi, part of a group often referred to as hyphomycetes, widely distributed in soil and associated with plants. Most species are harmless saprobes, and are relatively abundant members of the soil microbial community. Some species produce mycotoxins in cereal crops that can affect human and animal health if they enter the food chain. The main toxins produced by these ''Fusarium'' species are fumonisins and trichothecenes. Despite most species apparently being harmless (some existing on the skin as commensal members of the skin flora), some ''Fusarium'' species and subspecific groups are among the most important fungal pathogens of plants and animals. The name of ''Fusarium'' comes from Latin ''fusus'', meaning a spindle. Taxonomy The taxonomy of the genus is complex. A number of different schemes have been used, and up to 1,000 species have been identified at times, with approaches varying between wide and narrow concepts of speci ...
