PotatoTuberworm Damage - Tips For ControllingPotatoTuberworms.Most severe potatotuberworm damage results from the larvae eating into the potatotuber at the eyes. 1947. Control of Nosema disease of potatotuberworm, a host used in the mass production of Macrocentrus ancylivorus. Sci. The potatotuberworm, Phthorimaea. operculella (Zeller), is a pest of many. solanaceous crops, including potatoes. Commonly found in tropical and subtropical. The potatotuberworm: A literature review of its biology, ecology, and control. American Journal of Potato Research, 87(2), 149 – 166. Because potatoes are grown for their edible tubers, they must receive greater protection from soil-inhabiting pests. Wireworms, tuberworms, white grubs, and vegetable weevils are pests... Potatotuberworm, potato tubermoth (Phthorimaea operculella). Pest description and crop damage During the growing season, tuberworm caterpillars feed as leaf miners inside leaves. Additionally, the use of pheromone traps can detect potatotuberworm moth activity and help to pinpoint the correct timing for insecticide control. Abstract. The potatotuberworm Phthorimaea operculella is an important cosmopolitan quarantine pest of the Solanaceae crops. Comparing the relative virulence of five entomopathogenic... The potatotuberworm, Phthorimaea operculella (Zeller), has recently emerged as a potential eco-nomic pest of potatoes in the Pacific Northwest. Plants expressing Bt cry1Ac were effective in ing and toxicity, broaden the spectrum of controllingpotatotuberworm first-instar larvae in the detached-leaf bioassays... Insecticides for control of potatotuberworm and green peach aphid on potatoes in California. American Potato Journal. Adequate control of PTW is critical because larval infestation of tubers renders potatoes unmarketable. There is zero tolerance for the presence of tuberworm larvae in raw... The potatotuberworm, Phthorimaea operculella Zeller, is one of the most economically significant insect pests of potato in both field and storage worldwide. Pheromone traps can detect potato tuberworm moth activity and aid in the timing of insecticide applications for control. One option is to use water pan traps fixed with a protective lid from which the pheromone-laden bait is suspended. In decades past, people relied on pesticides to controlpotatotuberworms. Now we know that broad spectrum pesticides create resistant species and kill beneficial insects. Potato Tuberworm - Learn about the potato tuberworm, including its life cycle, control methods, habitat, physical description and alternative names Target PTW larvae feeding in the canopy in the weeks prior to vine desiccation or harvest. PHI is 7-days. Thorough coverage of foliage is essential. Use high water volumes with ground or aerial applications to ensure the product is well distributed in the foliage. Prompt harvesting after vine kill can be very effective. Harvesting under green vines may be best, since tuberworm seems to prefer living in the foliage. Keeping soil wet, especially as vines die, may be very important. The granulosis virus (Baculoviridae) is a promising biological control agent to protect post-harvest potatoes and in storage from the potatotuberworm.
