The Chewing Pest WG is a new group for IRAC combining the past Lepidoptera and Coleoptera WGs and complements the Sucking Pest WG. These two key groups sit within the IRAC Crop Protection Team along with the Nematode WG. It is recognised that the WG will have a broad remit given the potential range of crops and pests but, by focussing on specific areas, it is planned to deliver appropriate IRM strategies. Team Objectives Maintain currency of the global…
IRAC Israel is a new group formed in 2018 from an earlier Lepidoptera Working Group. The new Israel Country Group will now consider all aspects of insecticide resistance and its management. The initial objective of the group is to coordinate IRM guidelines and review methods to increase awareness of resistance management among stakeholders in Israel i.e. growers, distributors, field extension workers and researchers. Goals for 2018 include: Updating the Association Chamber of Commerce with activities and decisions of the group…

Representatives from BASF, Bayer, Corteva, FMC and Syngenta, attended this inaugural meeting when initial objectives and plans were discussed, and signed up as charter members to represent their companies. Further calls have now been held and a Steering…
INTRODUCAO A evolução da resistência de pragas a pesticidas tem sido um dos grandes entraves em programas de MIP em diversas culturas a nível mundial. Dentre as conseqüências da resistência estão a aplicação mais freqüente de produtos, uso de dosagens acima da recomendada no rótulo ou na bula do produto, uso indevido de mistura de produtos, e mudança de produto (geralmente para um produto mais caro e/ou mais tóxico) na tentativa de se obter um controle satisfatório de uma…
Tobacco thrips (Frankliniella fusca) is a pest of a wide range of economically important plants, including field crops, vegetables, peanuts and ornamentals. Frankliniella fusca can reproduce sexually or parthenogenetically. The lifecycle is completed in 15-25 days, with development from egg, 2 larval stages, pre-pupa, pupae through to adult. Adult thrips are small (1-2mm) and are brown or black in colour. Adults and larvae feed on new plant growth, with high infestations causing damage through plant disfiguration or growth inhibition. Frankliniella…
S. litura is an important insect pest of cotton. It causes heavy damage to cotton and lowers production. The adult is a dark brown moth with white lines on its wings. However, it is the worm-like young (larvae) that cause the damage. The larva is the size of your small finger and has bright yellow lines on the back and sides of the body. On touching, the larva curls at once and drops. Eggs are laid on the underside…
Besides onion and tobacco it attacks, among others: beans, broccoli, cabbage, carrot, cauliflower, cotton, cucumber, garlic, grapevine, leek, lucerne, melon, papaya, peach, peas, pineapple, potato, red beet, squash, tomato, turnip and many ornamental plants. Thrips tabaci is assumed to be of Mediterranean origin, but is nowadays found worldwide. It reproduces entirely parthenogenetically; males are very rare. The female lays about 30-80 whitish eggs into small gashes in plant tissue that it has cut with its ovipositor. The whole generation…
Sugarcane borer attacks plants in the family Gramineae (grasses). Though principally a pest of sugarcane, this insect also will feed on other crops such as corn, rice, sorghum, and sudangrass. Many wild or weed grasses are suitable hosts. It is native to the Caribbean, Central America, and the warmer parts of South America south to northern Argentina. Overwintering occurs in the larval stage, with pupation in the spring. Adults become active by April or May, and the borer population…
