Press Release from USDA:
Release of Endoparasite for the Biological Control of Asian Citrus Psyllid
APHIS published a draft environmental assessment on September 18, 2014 for the proposed release of Diaphorencyrtus aligarhensis for the biological control of the Asian citrus psyllid in the United States.
We will consider all comments that we receive on or before October 20, 2014.

The UC Riverside Veterinary Entomology Extension Laboratory has developed an on-line database of pesticides registered in the State of California for use against arthropod pests of animals. The database can be found at: Website visitors can search by animal commodity for which pest control is needed (e.g. poultry), by type of pest (e.g. poultry mite or house fly), and by application method and formulation. It is expected that animal producers and extension personnel will find this database to be much easier to navigate than the California Department of Pesticide Regulation product search website.
Animal producers may also be interested in other offerings of the Insect Pests of Animals website (). Visitors can find pest management information for some ectoparasite pests of poultry, cattle, and other animals. We are adding information on additional pests every few months so be sure to check back to see what has changed. We also maintain a Blog () that producers and extension personnel may be interested to follow. Information shared through the Blog includes recent findings related to pest management in animal facilities or of general relevance to animal producers, extension personnel, and researchers.
Finally, animal producers may be interested in taking a look at the many web links provided in our “other resources” section. In particular, there are links for producers to submit animal management questions to the national eXtension program through their “Ask and Expert” program. Experts from universities, extension offices, private industry, and other relevant organizations are registered with this national eXtension program to answer submitted questions or to provide question writers with guidance to address their questions.

Summer is upon us, and nothing quite says summer more than eating freshly picked blueberries or using them in delicious desserts. California blueberry growers can find an additional treat – the newly published UC IPM Pest Management Guidelines for blueberry on the UC IPM web site. California is quickly becoming a top producer of blueberries, and the new guidelines can help with management information on blueberry pests such as thrips, light brown apple moth, and spotted wing drosophila with additional information on pesticides and resistance.
It may be hard to believe but as of 1996, blueberry production was limited to colder states like Washington, Michigan, New Jersey, and Oregon, where naturally acidic soils and winter climates suit the traditional highbush varieties. As recently as 1997, California blueberries were only growing on less than 200 acres across the state. According to the latest CDFA statistics, 2012 continued to show what has been an increasing trend for California blueberries, with more than 40 million pounds harvested, $133 million sold, and plantings in more than 4,700 acres spanning San Joaquin, Tulare, Kern, Ventura, and Fresno counties.
In 1995 the University of California Small Farms Program and cooperating farmers started evaluating low-chill southern highbush varieties in San Luis Obispo and Ventura counties. They found that “low-chill” southern highbush varieties offered the most promise for extended season production on the central coast. By 1997, Kearney Agricultural Center trials found that southern highbush cultivars were also well adapted to the semiarid climate of the San Joaquin Valley. Further evaluations identified the best yielding and flavorful cultivars. Initial and ongoing UC Small Farms studies have escalated California blueberry production swiftly up the learning curve, providing California farmers of small to moderate operations a niche in a very competitive market.
Today, California blueberries are harvested from May through July in the San Joaquin Valley and January through May on the central coast. While consumer demands are on the rise and profits can be excellent, producing and harvesting blueberries in California is expensive. It can run over $10,000 per acre to prepare a field because successful cultivation in many areas necessitates soil and irrigation water acidification and adding tons of mulch per acre. Specialized equipment, labor-intensive pruning, and pests like light brown apple moth, thrips, and spotted wing drosophila can add substantially to cost. Therefore, getting the right information and planning is imperative. While the UC Small Farms Program continues to develop field and market research for blueberry production in California, growers can also turn to the newly published Pest Management Guidelines for blueberries.
At the IPM Training for Professional Landscapers meeting held in San Diego a couple of weeks ago, one of the speakers (from Blankinship and Asso.) gave a nice presentation about the permitting process needed when applying herbicides near or in waters. The NPDES permit has some upcoming changes so this presentation points out some of those changes as well.
If you, your company, or your agency is applying pesticides in those situations, it would good for you to review this presentation:
