16 Apr Abstract. Bactericera (Paratrioza) cockerelli (Šulc) (Hemiptera: Triozidae) is a native American psyllid species that was first reported in New. Bactericera cockerelli is found primarily on plants within the family Solanaceae. It attacks, reproduces, and develops on a variety of cultivated and weedy plant. General information about Bactericera cockerelli (PARZCO).

Field experiments showed seasonal differences in abundance of predators, with greatest abundance in spring and early summer Walker et al. Overwintering of the potato psyllid in the Northwest on Solanum dulcamara. Solanaceae in potato growing regions of Washington, Idaho, and Oregon.
Plant Disease, 97 8: Examples of solanaceous hosts for B. The male sometimes rubs cockerellii end of its abdomen on plant leaves.
Plant Disease, 97 9: This is to avoid the insects becoming resistant to an insecticide group. Dithiocarbamate fungicides for control of pear psylla.
The psyllid attacks, reproduces and develops on a variety of cultivated and weedy plant species Essig, ; Knowlton and Thomas, ; Pletsch, ; Jensen, ; Wallis,including crop plants such as potato Solanum tuberosumtomato Solanum lycopersicon bactericeraa, pepper Capsicum annuumeggplant Solanum melongena and tobacco Nicotiana tabacum as well as non-crop species such as nightshade Solanum spp. Using fluorescence in situ hybridization, Cooper et al.
Consequently, studies have been undertaken to evaluate the use of a mesh cover as a mechanical barrier for B. This table does not include results from the historic commercial seed lots and wild cocmerelli of Monger and Jeffries These descriptors, referred to as haplotypes, are consistent with biological differences psyllid vector and plant covkerelli and geographic distribution between these Ca.
Global Perspectives on Biology and Management [ed. A USA study on potatoes showed that if the psyllids are free from the bacterium, the plants will recover when the psyllids are removed.
Bactericera cockerelli (tomato/potato psyllid)
Description Top of page B. A brief history on the taxonomy and nomenclature of Bactericera cockerelli was recently provided by Butler and Trumble Insect Pests of Potato: John Anderson for information about the effect of the bacterium on quality of potato tubers. Encyrtidaewas described from B. Repellency of a kaolin particle film to potato psyllid, Bactericera cockerelli Hemiptera: However, it breeds poorly on some host plants and does not breed at all on other plant species in these families.
Pitman, personal communication and transmission in the plant is initially vertical, very likely because of genetic differences of ancestral lines. Eggs hatch days after oviposition Pletsch, ; Wallis, ; Capinera, ; Abdullah, Plant Disease, 94 3: Weed control could thus decrease pathogen reservoirs, decrease overwintering places for the vector, and perhaps also decrease vector populations and prevent vector movement.
Since its arrival in New Zealand, the psyllid was thought to transmit and spread a phytoplasma disease in potato crops, but this is now thought to be transmitted only by leaf hoppers.

The antennae are moderately long, extending almost half the length of the body. EPPO Global database available online. Studies on the Biology of Paratrioza cockerelli Sulc. Further evidence that zebra chip potato disease in the lower Rio Grande Valley of Texas is associated with Bactericera cockerelli.
The same fungi, except L. Most importantly, conventional pesticides may have limited direct disease control, as they may not kill the potato psyllid quick enough to prevent liberibacter and zebra chip transmission, bactericerra they may be useful for reducing the overall population of psyllids.
