Survey of Scale Insects Found on Imported Avocado and Dispersal of Scale Insects from Fruit to Host Plants 2011 Year End Report
February 2007, avocados from outside the U.S. were allowed into California for the first time. During the first months of importation, CDFA inspectors at the border between Arizona and California found several species of armored scale insects on avocados imported from Mexico, that were not known to occur in California nor anywhere in the U.S.
Survey for Armored Scales and their Natural Enemies on California Avocados 2011 Year End Report
Between 1914 and 2007, a quarantine protected California avocado groves from pests that might be introduced into the state along with fresh, imported avocados. Soon after Mexican avocados were first allowed entry on 1 February 2007, live specimens of several species of armored scales (Family
Dynamic Benefits of Invasive Pest Control in California Avocado Production
Sound management of and policy regarding newly introduced pests, and sanitary and phytosanitary regulations is achieved when the final costs and benefits to consumers and growers are known. The results of the study show that having the pesticide Agri-Mek available to treat infestations of ScritoS. perseae perseae (S. perseae) minimizes the losses to growers compared to use of the next best alternative. It also shows that while avocado growers are worse off and
Avocado Systemic Pesticides 2010 Year End Report
Current management practices for avocado thrips rely on the use of foliar insecticides. However, the number of products is limited, the mode of application can be difficult (helicopter use on steep hillsides, applications near urban regions, potential for groundwater contamination), and there are risks
Optimization of Systemic Chemicals for the Management of Avocado Pests
We are evaluating systemic insecticides for the management of current and newly emerging pests of California avocados. Current management practices for avocado thrips are centered on the use of foliar insecticides. Several foliar treatments are available (Agri-Mek, Delegate and Danitol) for the control of avocado thrips.
Evaluation of Systemic Chemicals for the Management of Avocado Pests Year End Report 2011
In this project, we are evaluating several members of the neonicotinoid insecticide class as potential control agents for avocado pests. In particular, there are several methods by which these chemicals can be applied to trees to achieve systemic uptake, and we are comparing the efficacy of each of
these methods to determine which is most effective. We conduct our research in commercial avocado groves so that our evaluations are realistic and relevant to California growers and grove conditions.
