Introducing P.S.H.B. PheroLure©:

A powerful tool for monitoring polyphagous shot hole borer

Insect Science, a leading semiochemical manufacturer, is thrilled to announce the development of P.S.H.B. PheroLure© to aid in monitoring for polyphagous shothole borer (Euwallacea fornicatus). A type of active called quercivorol attracts female PSHB beetles to the trap. This allows for early PSHB detection and intervention in the hopes of curbing its spread from urban to agricultural areas. Through extensive field trials, this pheromone lure has demonstrated exceptional efficiency in catching PSHB, equivalent to industry-standard PSHB lures sold worldwide.

POLYPHAGOUS SHOTHOLE BORER

The PSHB is an ambrosia beetle from Southeast Asia that has a symbiotic relationship with the Fusarium euwallaceae fungus and is an invasive species in California, Israel, Australia, and South Africa. It poses a threat to various sectors, including agriculture, commercial forestry, urban trees, and native trees in natural forests, leading to branch die-back and potential tree mortality. PSHB lifecycle Female beetles bore into host trees, making galleries in the Xylem area. They carry the Fusarium euwallaceae fungus in their mouth parts, infecting the galleries and spreading throughout the tree. After 8 days, females lay eggs at the end of the galleries. Within days, the eggs hatch, and the larvae feed on the fungus. Adults emerge from the trees in about one month. With a high ratio of females, just one mated female can establish a whole new population, making control challenging.

MONITORING INFORMATION

The field efficacy of the Insect Science P.S.H.B. PheroLure© has been proven to sustain a constant catch for at least six weeks, particularly during summertime conditions. This extended efficiency eliminates the need for frequent lure replacement.

To ensure optimal performance, it is recommended to tie the lure to the trap or sticky card using the hole punched at the top of the provided lure. Additionally, unused lures should be stored in a freezer to maintain their efficacy. It is crucial not to compromise the lure pouch by opening or puncturing it, as this may significantly decrease its effectiveness.

While our lure is predominantly selective for the PSHB, it is important to note that it may also attract related pests such as the Tea shot hole borer and the Kuroshio shot hole borer. However, the primary target remains the PSHB.

Remember to conduct visual surveys to inspect entry holes and Xylem leakage, and dying branches on the host tree. If the infestation is severe, consider complete removal and incineration of the tree.

DISTRIBUTION PARTNER

Insect Science is proud to collaborate with Biological Ag, our esteemed distribution partner in Australia, in making this valuable tool available for professionals working in the fields of entomology, forestry, agriculture, and Integrated Pest Management. Together, we can combat the damage caused by PSHB and protect our valuable ecosystems from the devastating effects of the accompanying Fusarium fungi.
