| curtovirus-cucurbit interaction: acquisition host plays a role in leafhopper transmission in a host-dependent manner. | curly top disease (ctd) of vegetable crops is caused by viruses in the genus curtovirus (family geminiviridae). cucurbits are reported to be susceptible to ctd; however, the disease is rare in california despite annual outbreaks in other hosts (e.g., common bean, pepper, sugar beet, and tomato). consistent with these observations, no obvious curly top symptoms were observed in melon fields surveyed for ctd in central california in 2004 and 2005, whereas the disease was readily observed in tomato ... | 2009 | 19055441 |
| aggregation behavior and a putative aggregation pheromone in sugar beet root maggot flies (diptera: ulidiidae). | male-biased aggregations of sugar beet root maggot, tetanops myopaeformis (röder) (diptera: ulidiidae), flies were observed on utility poles near sugar beet (beta vulgaris l. [chenopodiaceae]) fields in southern idaho; this contrasts with the approximately equal sex ratio typically observed within fields. peak observation of mating pairs coincided with peak diurnal abundance of flies. volatiles released by individual male and female flies were sampled from 08:00 to 24:00 hours in the laboratory ... | 2017 | 28423428 |
