The best way to control shothole borer—and any other bark beetle—is to cut out weak branches and remove all dead wood, including prunings, from in and around the orchard.
How do I know if I have shot hole borers?
How To Identify The Shot Hole Borer:
- Wilting trees.
- Dead branches.
- Exit/Entry holes on the bark of the trees.
- Shotgun-like lesions on the bark at entry/exit holes.
- Sugar volcanoes on the bark at entry/exit holes.
- Blotches of oozing resin on the bark at entry/exit holes.
How do invasive shot hole borer find their mate?
Both males and females spend most of their lives inside trees within channels called galleries that the females create by boring into trunks or branches. Once the larvae grow into adults, the beetles will mate inside the galleries, and females will disperse, ready to start their life cycle over again.

What Is The Polyphagous Shot Hole Borer? The Polyphagous Shot Hole Borer, also known as Euwallacea fornicatus, is a troublesome species that is able to cause a great deal of damage to the environment. The beetles are approximately 2 mm long and native to Southeast Asia.
Where does borer originate?
Borer Beetle larvae emerge from eggs laid by the adult beetles on bare wood or old flight holes. The larvae eat their way through the interior of the wood for 2-4 years and then pupate just below the surface before emerging as an adult and eating their way out creating a new flight hole.
What are ISHB reproductive host trees?
About Reproductive Hosts ISHB or Fusarium dieback hosts may be trees identified as showing signs of beetle or beetle and fungal attack in the field, or trees specifically challenged with beetles and/or fungal pathogens in controlled experiments.
What type of insect is a Polyphagous shot hole borer?
ambrosia beetle
(“Polyphagous” means “eats lots of things.”) Drill says the PSHB is a type of ambrosia beetle, apparently from Vietnam. Unlike bark beetles, these pests tunnel into a host tree, bringing along fusarium fungi that they farm as food. The shot hole borers reproduce inside the galleries in the host, mating with siblings.
How do you control the thrips in a pomegranate?
Spray Dimethoate 30 EC @1.7 ml or Oxydemeton methyl 25 EC @ 1.5 ml or imidacloprid 17.8 SC @ 0.3 ml per liter of water. Spray Dimethoate 0.06% prior to flowering is important and in severe condition spray methyl oxy-demeton 0.05% and repeat after fruit set.
How do you control fruit borer in a pomegranate?
Spray one of the following chemicals: dimethoate (2 ml/lit), indoxacarb (1 g/lit), cypermethrin (1.5 ml/lit) or profenophos (2 ml/lit) at a fortnightly interval from flowering to fruit development. Chemical applications of lambda-cyhalothrin are also recommended for effective control of pomegranate fruit borer.
What trees are affected by shot hole borer?
One or both of these beetles are known to feed and reproduce in California in about 60 tree species. For example, avocado, California sycamore, castor bean, coast live oak, cork oak, Fremont’s cottonwood, and Persian silk tree can be infested with both Kuroshio shothole borer and polyphagous shothole borer.
What is a shot hole borer?
Shothole borers are small beetles that were introduced from Europe and have spread over most of the United States and southern Canada. They were first reported in the Northwest in the early 1900s. They are destructive pests of forest trees but also attack fruit, shade and ornamental trees and shrubs.
Where did the tea shot hole borer come from?
The tea shot-hole borer was first described by Eichhoff in 1868 and originally classified in the genus Xyleborus. A very closely related species, the polyphagous shot hole borer ( Euwallacea n. sp.), is a similar species originally from Asia which is now invasive in California and Israel.
What is Euwallacea perbrevis (tea shot hole borer)?

Euwallacea perbrevis (tea shot-hole borer); damage in a tea stump showing galleries. Species in Euwallacea and related genera are currently considered quarantine pests.
How many different types of shot hole borer are there?
Several specimens in the native and introduced range fitting the species description were found to be genetically different, with three recognized clades named as tea shot-hole borer (TSHB), polyphagous shot hole borer (PSHB) and kuroshio shot hole borer (KSHB) ( Stouthamer et al., 2017 ).
Which species are the most successful invaders of wood borers?
Members of the tribe Xyleborini (which includes the genus Euwallacea) are some of the most successful invaders, as they are commonly intercepted at ports of entry, and because of biological and ecological characteristics, they also get easily established compared to other wood borers ( Brockerhoff and Liebhold, 2017 ).
