A tiny wasp may be the solution for managing an agricultural pest causing major economic damage to fruit, vegetable, and field crops in North America and Europe. Agricultural Research Service (ARS) scientists are currently studying Trissolcus japonicus, commonly known as the samurai wasp, to see if this parasitoid wasp is the right biological control agent for reducing brown marmorated stink bug (Halyomorpha halys) (BMSB) populations outside of Asia. Biological control is the process of reducing or mitigating pests or pathogens by using the pest’s or pathogen’s natural enemies. The samurai wasp is a known natural enemy for the BMSB in Asia, and researchers are understanding how it behaves in non-native environments.

The environmental tolerances and potential range of the tomato pest Tuta absoluta in Africa, the Arabian Peninsula, Central Asia and Australia may have been underestimated according to new research co-authored by CABI scientists. All results from the scientists' research suggests with the greatest certainty that T. absoluta (also known as Phthorimaea absoluta or tomato leafminer) has further to spread globally, particularly in southern and East Asia, Australia and Central America.

Australia is lucky to be free from many of the world’s most damaging plant pests. Exotic plant pests are capable of damaging our natural environment, destroying our food production and agriculture industries, and some could change our way of life. Australia’s biosecurity system helps protect us from exotic plant pests. The Department of Agriculture, Water and the Environment manages this system with state and territory ​governments, industry and the community. The Plant Health Committee has recently reviewed the National Priority Plant Pests that are exotic to Australia, under eradication or have limited distribution. These are the focus of government investment and action, including funding through the Priority Pest and Disease Planning and Response. While by no means the only plant pests of biosecurity concern, the National Priority Plant Pests serve to highlight the sort of threats Australia faces.

The Colorado Division of Wildlife is monitoring the state's waters for the introduction of an aggressive invasive species, the rusty crayfish. Rusty crayfish were found for the first time in Colorado during routine sampling operations in 2009 in the Yampa River drainage between Steamboat Springs and the town of Yampa. Because of their larger size and more aggressive nature, rusty crayfish can impact fish populations by consuming small fish and fish eggs, and negatively impact fish and spread unwanted aquatic plants by aggressively harvesting underwater plant beds. Learn more how to identify the rusty crayfish, how to stop the spread and how to report sightings.
