Manipulation of Natural Enemies in Agroecosystems: Habitat and Semiochemicals for Sustainable Insect Pest Control
Plants are not capable of running away from their enemies, i.e., the herbivores that may eat them. However, under certain circumstances, plants can rely on the natural enemies of insect herbivores for protection. These natural enemies include other insects that are predators and parasitoids. To help protect plants from damage caused by insect herbivores, practical methods have been developed an...
متن کاملwillingness to communicate in the iranian context: language learning orientation and social support
why some learners are willing to communicate in english, concurrently others are not, has been an intensive investigation in l2 education. willingness to communicate (wtc) proposed as initiating to communicate while given a choice has recently played a crucial role in l2 learning. it was hypothesized that wtc would be associated with language learning orientations (llos) as well as social suppo...
manipulation in dubbing and subtitling
پژوهش حاضر در چارچوب مکتب دستکاری قرار گرفت و با استفاده از تقسیم بندی دوکات (2007) از شیوه های دستکاری، به دنبال یافتن پاسخ برای پرسش های زیر بود: 1-رایج ترین شیوه دستکاری در دوبله فیلم ها کدام است؟ 2-رایج ترین شیوه دستکاری در زیرنویس فیلم ها کدام است؟ 3-دستکاری در دوبله فیلم ها رایج تر است یا در زیرنویس آن ها؟ این پژوهش از نوع تحقیقات توصیفی- مقایسه ای و پیکره ای می باشد. پیکره تحقیق شا...
Ant semiochemicals limit apterous aphid dispersal.
Some organisms can manipulate the nervous systems of others or alter their physiology in order to obtain benefit. Ants are known to limit alate aphid dispersal by physically removing wings and also through chemical manipulation of the alate developmental pathway. This results in reduced dispersal and higher local densities of aphids, which benefit ants in terms of increased honeydew and prey av...
متن کاملOptimal Foraging in a Uniform Habitat: The Search Mechanism of the Green Lacewing
The effects of food deprivation and prey contact on the components of searching behavior in larval green lacewings (Chrysopa carnea Stephens) were examined to test the applicability of optimal foraging theory to predation in a uniform habitat. Variation in foraging intensity was primarily the result of changes in the meander. Modulation of the response to prey contact with increasing deprivatio...
