An exploratory analysis of the structure of tetranychid and phytoseiid assemblages in walnut orchards in California.

Spider mites were considered secondary pests of walnut production in California, under the control of phytoseiid predators. Due to increased importance as walnut pests in recent decades there is renewed interest in the structure and function of the associated phytoseiid assemblage. In this study we report the results from a 3 year survey of the tetranychid and phytoseiid assemblages in walnut orchards in the Central Valley of California.

Evaluation of a 'Preventative' Strategy to Manage Spider Mites on Almond.

Field experiments were conducted in two commercial almond orchards located in the southern San Joaquin Valley during 2016 and 2017 to evaluate a "preventative" strategy to manage spider mites. Pacific mite, McGregor, was identified as the only mite species infesting the experimental sites in both years. We monitored mites weekly in 3.

Cold Tolerance and Population Dynamics of (Hemiptera: Coreidae).

In California's San Joaquin Valley, feeding by the coreid pest, , can cause considerable economic loss on almond and pistachio. This research was conducted to improve understanding of how winter temperatures affect mortality of overwintering adult and to develop a better understanding of the role pomegranate plays in the species' life-history. We exposed 7410 field-collected adult to temperatures between -2 and -10 °C for a period of three, four, or six hours using insect incubators.
