Although tomato psyllid, Bactericera cockerelli (Sulc) (Homoptera, Psyllidae), annually causes significant losses in potato and tomato crops in eastern Mexico and the central United States, infestations in western North America have been historically rare. However, substantial populations appeared in 2001 in western North America and caused losses in tomato production exceeding 80%; losses in 2...

The lerp-forming psyllid, Creiis lituratus Froggatt, is the most damaging pest of Eucalyptus dunnii Maiden plantations growing in north-eastern New South Wales. During the past 10 years there have been numerous reports that stands of E. dunnii planted on low-lying areas that were prone to waterlogging were also prone to infestation by C. lituratus. The objective of this shadehouse study was to ...

'Candidatus Liberibacter solanacearum' (Lso) is a phloem-limited bacterium that severely affects important Solanaceae and Apiaceae crops, including potato, tomato, pepper, tobacco, carrot and celery. This bacterium is transmitted to solanaceous species by potato psyllid, Bactericera cockerelli, and to Apiaceae by carrot psyllids, including Trioza apicalis and Bactericera trigonica. Five haploty...

The prediction of product acceptability is often an additive effect of individual fuzzy impressions developed by a consumer on certain underlying attributes characteristic of the product. In this paper, we present the development of a data-driven fuzzy-rule-based approach for predicting the overall sensory acceptability of pistachio green hull’s marmalade. The model was formulated using the Tak...

This paper describes total determination of aflatoxins B1 and B2 in pistachio samples using corona discharge ion mobility spectrometry (IMS). A new injection port was designed to introduce liquid samples into the IMS. Using this port, the liquid solvent (methanol) containing standard aflatoxins or an extracted sample was directly introduced into the injection port. Calibration curves resulting ...

The African citrus psyllid, Trioza erytreae (Hemiptera: Triozidae), is a vector of greening (Huanglonbing - HLB), bacterial disease caused by Candidatus liberibacter spp. Native to Africa, T. was detected in the Canary Islands and Madeira early 2000s then northwestern Spain 2014. Since then, has become established along Atlantic coastal areas Iberian Peninsula. Therefore, an accurate assessment...

Abstract Background The tomato psyllid, Bactericera cockerelli Šulc (Hemiptera: Triozidae), is a pest of solanaceous crops such as ( Solanum lycopersicum L.) in the U.S. and vectors disease-causing pathogen ‘ Candidatus Liberibacter solanacearum’. Currently, only effective strategies for controlling diseases associated with this involve regular pesticide applications to manage psyllid populatio...
