Abstract:
... The psyllid Bactericera maculipennis (Crawford) (Hemiptera: Triozidae) often cohabits field bindweed (Convolvulus arvensis, Solanales: Convolvulaceae) and other plants with the congeneric psyllid, Bactericera cockerelli (Sulc), in the Pacific Northwestern United States. Bactericera cockerelli is a vector of “Candidatus Liberibacter solanacearum,” the pathogen associated with zebra chip disease of ...

Abstract:
... Worldwide mobile telephone and microwave use have resulted in an increasing presence of extremely low-frequency electromagnetic field radiations (ELF-EMFs) in ecosystems. ELF-EMFs have been associated with altered physiological processes that can adversely affect exposed organisms. In this study, Trichoplusia ni Hübner larvae were exposed for 24, 48, or 72 h to ELF-EMFs (60 Hz and 2.0 mT) to asses ...

Currently, most blueberry growers use honey bees (Apis mellifera L.) to provide pollination services for highbush blueberries even though bumble bees (Bombus spp.) have been shown to be more efficient at pollinating blueberries on a per bee basis. In general, contribution of bumble bees to the pollination o ...

In termites (Isoptera), it has mostly been reported in higher termites, but elements of age polyethism were recently found in juvenile colonies of a lower termite, Coptotermes formosanus Shiraki (Rhinotermitidae). The objective of this study was to compare age polyethism in immature colonies ...

The mites Oligonychus perseae and Oligonychus punicae have a broad range of host plants, but, to date, records of them coexisting sympatrically had only been reported on avocado. However, our field observations showed both species coexisting on host plants other than avocado. The lack of previous records of thes ...
