They pass through five nymphal stages. Common Tomato Problems. First, feeding by potato psyllid nymphs, and sometimes adults, can result in psyllid yellows, the symptoms of which include stunting and chlorosis of leaves, and in extreme cases plant death; psyllid yellows is believed to be the result of a currently unidentified toxin (Butler and Trumble 2012a). Home garden tomatoes are more likely to be damaged by the psyllid this year, because the pest lived through the winter in some areas of the county, and the summer migration of psyllids from Mexico has already begun. Below are photos, average fruit weight, and production notes for each of the varieties. The potato/tomato psyllid Bactericera cockerelli causes serious damage to several solanaceous crops by direct feeding and vectoring Candidatus Liberibacter solanacearum, a bacterial pathogen. Phosphorus is abundant in our soils but may be unavailable to the plant when the soil is too cold. The Potato/Tomato Psyllid Jeffrey Bradshaw, Extension Entomologist Alexander D. Pavlista, Extension Potato Specialist Robert Harveson, Extension Plant Pathologist Outbreaks of potato/tomato psyllid are sporadic but occur suddenly over vast areas of North America, including Nebraska. Damage symptoms of Potato/tomato psyllid in Pumpkin, squash and gourd The main direct damage, caused by potato psyllid nymphs when feeding, is known as ‘psyllid yellows’, which results in delayed growth, weakness in the new leaves, chlorosis/reddening or purple colouration of the leaf bases and internodes, and poor-quality fruit. Home garden tomatoes are more likely to be damaged by the psyllid this year, because the pest lived through the winter in some areas of the county, and the summer migration of psyllids from Mexico has already begun. Symptoms of psyllid infestation to look for Look for damage on the underside of leaves. Differential responses to feeding by the tomato/potato psyllid between two tomato cultivars and their implications in establishment of injury levels and potential of damaged plant recovery. Department of Entomology, University of California, Riverside CA, USA . The adult form of the potato and tomato psyllid. Tomato potato psyllid (TPP) is a tiny sap-sucking insect that on feeds on tomatoes, potatoes, and other related plants, such as capsicum, chilli, goji berry, tamarillo, eggplant and sweet potato. Potato/tomato psyllid (Bactericera cockerelli). TPP primarily feeds on potatoes, tomatoes and capsicums, but can be found on approximately 20 other plant families. Phosphorus deficiencies (Figure 1) occur early in the growing season when soil is still cool. The bacterium is believed to cause diseases such as ‘ psyllid yellows ’ in tomatoes and potatoes, and ‘ … Yields were so compromised by the season (cool weather and hail damage) that we are not reporting yield data. Outbreaks of potato/tomato psyllid are sporadic but occur suddenly over vast areas of North America, including Nebraska. Variation between the susceptibility of tomato cultivars occurs, but the relative susceptibility of New Zealand cultivars is unknown. Life Cycle Potato/tomato psyllids pass through three life stages: egg, nymph (immature stage) and adult. Damage to capsicum is usually less severe. Outbreaks of potato psyllids (Paratrioza cockerelli) are very sporadic but have occurred suddenly and over vast areas. The psyllid probably attacked some back yard tomatoes last year, but gardeners likely attributed any damage to other causes. Damage symptoms include stunting, chlorosis and purpling of leaves, distorted leaf growth and stem death. tomology Section indicates that serious damage to tomatoes was noted in 1898, 1904, 1906, 1911, 1912, 1915, and 1916. For specific information describing tomato-potato psyllid carriers, and the movement restrictions and conditions that must be met to move the carriers into Queensland, go to the Queensland Biosecurity Manual (PDF, 1.8MB) . The tomato potato psyllid can carry the bacterium “Candidatus Liberibacter solanacearum”, which is associated with the ‘zebra chip’ disease in potato. The tomato plants also appeared to have psyllid yellows around August 31st. Image copyright: Western Australian Agriculture Authority (Dept of Ag & Food, WA) Tomato potato psyllids are most active in warmer months and less so in winter. The Potato/Tomato Psyllid. Signs of tomato potato psyllid include: • Insects jumping from the foliage when disturbed. Psyllid problems do not occur every season. They are very small insects, the adults are about the size of the head of a pin while the damaging nymph is closer in size to the point of a pin. The following are ranked with the pesticides having the greatest IPM value listed first—the most effective and least harmful to natural enemies, honey bees, and the environment are at the top of the table. Figure 5: Symptoms of early blight. POTATO (TOMATO) PSYLLID. Psyllids are most found from the Rio Grande River valley and north in the High Plains States. Overseas the tomato potato psyllid can also carry a bacteria (Candidatus Liberibacter solanacearum) which causes a disease known as zebra chip. Psyllid nymphs have been detected on a tomato plant in Kaysville. Damage caused by tomato potato psyllid. Names link to information on identification and management. The tomato potato psyllid can carry the bacterium “Candidatus Liberibacter solanacearum”, causing the ‘zebra chip’ disease in potato. As the cankers grow, they encircle the stem, causing the plant to die. Monitor their appearance and protect potato, tomato, pepper, and eggplant using chemical control. Tomato-potato psylid are readily attracted to yellow sticky traps, and will indicate the presence of this pest. The small size of tomato psyllids makes them difficult to see on tomato plants. Tomato psyllid nymph; Whiteflies damage; Use the photos below to identify pests and damage you may see during preharvest time such as whiteflies, leafminers, hornworms, lygus, cutworms, psyllids, tomato pinworms, and flea beetles. damage to tomatoes or potatoes frequently occurs before the problem is detected. Tomato Potato Psyllid (Bactericera cockerelli) A known pest of the USA and Canada, and New Zealand as recently as 2006, the Tomato Potato Psyllid (TPP) has recently been found on the west coast of Australia. Feeding at immature stages sometimes causes a physiological foliage disorder known as "psyllid yellows" in potatoes. Damage has been reported almost every season in recent years. Potato & tomato psyllid Psyllid eggs along the edge of a leaf, plus an adult. Electron beam (eBeam) irradiation is an environmentally friendly, chemical‐free alternative method that is increasing in use for disinfestation of insect pests. Look at this poorly tomato. These insects are around the size of aphids and look like tiny cicada. Tomato-potato psyllid carriers can be plants, fruit and vegetables, soil and equipment or appliances. Figure 2: Psyllid damage. Tomato/potato psyllid adults and nymphs cause damage to host plants through feeding on leaves and by transmitting a bacterial pathogen, Liberibacter, that lives in plants. The potato/tomato psyllid, Bactericera cockerelli (Sulc) (Hemiptera: Triozidae) has been a major pest of solanaceous crops for decades.
