Zusammenfassung: | The potato psyllid,
Bactericera cockerelli
(Šulc) (Hemiptera: Triozidae), is a key potato (
Solanum tuberosum
L.) pest that has the ability to vector the plant pathogenic bacterium Candidatus Liberibacter solanacearum (Lso), the putative causal agent of zebra chip disease of potato. The insect primarily feeds and completes its life cycle on Solanaceous crops and weeds; however, in the Columbia Basin of Oregon and Washington,
B. cockerelli
has been found in association with crops such as maize (
Zea mays
L.) and wheat (Triticum spp), both belonging to the Poaceae family. We hypothesize that this is due to the presence of volunteer potato; in this region, the potato crop is in a 3-yr rotation with either maize or wheat. Consequently, we evaluated potato, maize, wheat, maize + volunteer potato, wheat + volunteer potato on captures of
B. cockerelli
adults in a 2-year field experiment using an inverted leaf blower and yellow sticky cards. Data collected in this study confirms that
B. cockerelli
has an affinity for potato, although,
B. cockerelli
could be found in maize and wheat mainly when volunteer potatoes were present. In addition,
B. cockerelli
counts varied depending if using inverted leaf blower or yellow sticky cards. Knowing that
B. cockerelli
is found in fields where volunteer potatoes are present, it should be taken into consideration for large-scale potato psyllid management. |
