Here are summaries of some of the IPM research, innovations and projects going on in Arizona, or benefitting Arizona agriculture, communities and natural areas. Projects listed here are not necessarily funded by the Western IPM Center.

 

Tribal Bed Bed Workshop Dispels Myths

There is a lot of fear about bed bugs, and a stigma surrounding them that can keep some people from seeking help with a bed bug infestation.

But bed bugs have been hanging around humans for a long time and aren’t going anywhere anytime soon. That was one of the key messages at a bed bug workshop last month for tribal communities in California, Nevada and Arizona.



Decoding Chemical Communications to Control Insects

University of California, Riverside chemical ecologist Jocelyn Millar identifies the chemical signals insects use to communicate, then synthesizes versions of them to help monitor, trap or disrupt their activities. 

Lygus bug is just one of dozens of species Millar and his team are working on. The common thread is that they all communicate chemically, and decoding those chemical signals can create new ways to control those species where they are pests.



Gold Spotted Oak Borer Threatens Oak Woodlands and Ecosystems across Southern California

From San Diego County to Los Angeles County, oak trees are dying rapidly, killed by a tiny beetle called the gold spotted oak borer. In areas where the invasive pest has become established, it’s killing 80 to 90 percent of the mature oaks – a dieback that’s fundamentally changing the landscape and the ecosystem the oaks support.



VIDEO: Functional Agricultural Biodiversity

Farmers embracing functional agricultural biodiversity incorporate habitat for beneficial insects and wildlife on their farms - and benefit from the ecosystem service that habitat provides.



VIDEO: Where to Get Good Gardening Advice

In this video, Ariel Agenbroad from University of Idaho offers great tips for home gardeners about where to get good pest-management advice.

VIDEO: Gold Spotted Oak Borer, or GSOB, in Irvine Regional Park

Weir Canyon in the Irvine Regional Park is the only known infestation of gold spotted oak borer in Orange County - and land managers are working hard to protect the park and keep the destructive beetle from spreading.



VIDEO: Gold Spotted Oak Borer, or GSOB, in Southern California

The gold spotted oak borer is a tiny beetle causing huge damage in Southern California. It infests the region's towering oak species - coast live oak and canyon live oak - and can kill a centuries-old tree in just a year or two.

This video follows the beetle from San Diego to Los Angeles counties to see what damage it's doing and what many fear may come next.



Toolkit for Assessing IPM Outcomes and Impacts

The Western IPM Center’s IPM Adoption and Impacts Assessment Work Group, a collection of natural and social scientists from across the country, created online resources showing IPM researchers how to conduct basic impact assessments.



South American Palm Weevil

The South American palm weevil is a serious palm pest in its native range in Mexico, Central and South America. It is highly likely that the insect has established permanent populations in southern San Diego County in an area that ranges, at least, from San Ysidro to Chula Vista. 



Hill-Climbing Cows May Bring Big Benefits to Western Rangeland and Ranchers

Conventional wisdom says cows don’t go up steep slopes. They don’t climb hills and don’t travel very far from water.

But some cows never got that memo.



Eco-Label Programs Promote IPM, but Aren't Perfect

There are dozens of eco labels and sustainable agriculture certification programs in the United States, all designed to differentiate products in the marketplace and assure consumers that this apple, potato or bottle of wine was produced in an environmentally responsible manner. 

And eco-label programs do have clear benefits and promote more sustainable pest-management and growing practices. They also provide certain benefits for growers. 

However, there are downsides for growers as well, and significant differences between the programs can make judging eco labels challenging for consumers. And with dozens of similar yet competing certification programs and standards, certification chaos is likely for the foreseeable future.

 


Can an Economic Model Show Growers the Importance of Reducing the Weed Seed Bank?

How important is it to keep weed seeds out of vegetable fields?

Mexico State University's Brian Schutte recently looked at that very question. Funded by the Western IPM Center, Schutte studied one particular weed, tall morning glory, in Southwest chile pepper fields, and developed an economic model growers can use to see for themselves how managing the weed seed bank can help their operations.



School IPM Protects Kids from Pests and Pesticides

Both pests and pesticides are potentially harmful for kids and adults in schools. Common schools pests like the German cockroach or mice can carry disease and cause allergic responses. And children can be more at risk for harm from sprayed pesticides because of their behavior – playing on the floor or in grassy fields, for instance – and because of their developing physiology.



Grazing Guidelines for Noxious Weed Control

Researchers, ranchers, and land managers know that livestock grazing can be a valuable and selective noxious-weed management tool, and this guide summarizes all the effective techniques.



IPM Adoption is Widespread in the West

Many integrated pest management practices are so widely adopted in Western agriculture they have become conventional pest management. That is one of the key findings of a new report by the Western Integrated Pest Management Center titled “Adoption and Impacts of Integrated Pest Management in Agriculture in the Western United States.”



New Guide Helps Land Managers Control Medusahead

As an ecosystem-transformer species, medusahead is among the worst weeds. Not only does it compete for resources with more desirable species, but it changes ecosystem function to favor its own survival at the expense of the entire ecosystem.



Boosting Invasive Species Cooperation Using Zebra Chip as a Model

When an invasive species is first detected in an area, the initial response is critical. Like with a cancer, the correct early detection and response can make a big difference in controlling the spread and severity of the outbreak.



Protecting Kids from Pests and Pesticides by Promoting IPM in Schools

Both pests and pesticides in schools can pose a health risk to children, so promoting IPM practices in schools is doubly important. That's why the Western IPM Center has been helping Western researchers develop regional resources and promote school IPM.



Using IPM Techniques to Battle Bed Bugs in Public Housing

Public housing presents unique pest-management challenges, including rapid turnover of residents, language and cultural barriers and even second-hand clothing and furniture. And those pest problems – especially when bedbugs are involved – can lead residents to resort to some pretty drastic and harmful pest control strategies.
