1.17 The drudgery of weeding is so ingrained into the lives of farmers in developing countries that weeds are taken for granted and often overlooked in pest surveys. And yet weeding by hand, typically carried out by women and children, accounts for 50% of the total labour inputs needed to produce a crop, deprives millions of children the joys of playtime – and often schooling – and adds to the ...

JUSTIFICATION: Armillaria root disease is associated with various forest tree declines in the Rocky Mountain Region and has been suggested to play a role in tree mortality that is usually attributed only to bark beetles. Armillaria has been documented as a major forest pest in the states surrounding Wyoming, yet an evaluation of the significance of this root pathogen in Wyoming is lacking. Give...

Recent surveys and sample collection have conWrmed the endemicity of Dermanyssus gallinae in poultry farming worldwide. The reduction in number and eYcacy of many acaricide products has accentuated the prevalence rates of this poultry ectoparasite observed more often in non intensive systems such as free-range, barns or backyards and more often in laying hens than in broiler birds. The lack of ...

Ecological communities used in biological pest control are usually represented as three-trophic level food chains with top-down control. However, at least two factors complicate this simple way of characterizing agricultural communities. First, agro-ecosystems are composed of several interacting species forming complicated food webs. Second, the structure of agricultural communities may vary in...

Insect pests are a major threat to agricultural biosecurity across the world, causing substantial economic losses. Majority of the species distribution modeling studies use precise coordinates (latitude/longitude) of species occurrences in MaxEnt (or maximum entropy model). However, lack of precise coordinates of insect pest occurrences at national/regional level is a common problem for many co...

Drosophila suzukii Matsumura, 1931 (Diptera: Drosophilidae) is an invasive pest species that causes damage to fruit crops due premature deterioration of ripe fruits by oviposition inside them. A review D. detections in Argentina was carried out and we updated this list with the results our sampling Northwest, Cuyo Northeast regions. The surveys determined first provinces Jujuy Córdoba, revealin...
