Biological control or biocontrol is a method of controlling pests such as insects , mites , weeds and plant diseases using other organisms. It can be an important component of integrated pest management IPM programs. There are three basic strategies for biological pest control: classical importation , where a natural enemy of a pest is introduced in the hope of achieving control; inductive augmentation , in which a large population of natural enemies are administered for quick pest control; and inoculative conservation , in which measures are taken to maintain natural enemies through regular reestablishment.

Extension Pesticide Program. Host - A plant or animal on or in which a pest lives. Juvenile hormones - Natural insect chemicals that keep the earlier stages of an insect from changing into the normal adult form. Labeling - The pesticide product label and other accompanying materials that contain directions that pesticide users are legally required to follow Mycoplasmas - The smallest known living organisms that can reproduce and exist apart from other living organisms.

Biological pest control

In a natural ecosystem, plants are continuously being attacked by all kinds of pests and pathogens such as insects, fungi and bacteria. In the natural ecosystem plants can survive thanks to the help of natural enemies of these unwanted pests and pathogens. In this way, population developments of all players in a natural ecosystem are controlled. But compared to nature, cropping systems are less stable due to human interferences. This often results in the populations of the naturally occurring enemies being too small or developing too late, resulting in diseased or damaged plants. Biological control is the release of extra natural enemies to suppress pests and diseases in crops.

Plant diseases need to be controlled to maintain the quality and abundance of food, feed, and fiber produced by growers around the world. Different approaches may be used to prevent, mitigate or control plant diseases. Beyond good agronomic and horticultural practices, growers often rely heavily on chemical fertilizers and pesticides. Such inputs to agriculture have contributed significantly to the spectacular improvements in crop productivity and quality over the past years. Today, there are strict regulations on chemical pesticide use, and there is political pressure to remove the most hazardous chemicals from the market.

Let Your Life Speak: Listening for the Voice of Vocation

В подобной ситуации надо известить только одного человека - старшего администратора систем безопасности АНБ, одышливого, весящего четыреста фунтов компьютерного гуру, придумавшего систему фильтров Сквозь строй. В АНБ он получил кличку Джабба и приобрел репутацию полубога. Он бродил по коридорам шифровалки, тушил бесконечные виртуальные пожары и проклинал слабоумие нерадивых невежд. Чатрукьян знал: как только Джабба узнает, что Стратмор обошел фильтры, разразится скандал. Какая разница? - подумал.  - Я должен выполнять свои обязанности. Он поднял телефонную трубку и набрал номер круглосуточно включенного мобильника Джаббы.

UNIT 1: Principles of Pest Control

Все крупные провалы в сфере безопасности в истории агентства происходили внутри этого здания. В обязанности Мидж как эксперта по обеспечению внутренней безопасности входило наблюдение за всем, что творилось в стенах АНБ… в том числе и в кладовке столовой агентства. Бринкерхофф поднялся со своего места, словно стоя ему было легче защищаться, но Мидж уже выходила из его кабинета.

В дальнем углу, прямо под табло, которое когда-то показывало счет проходивших здесь матчей, он увидел слегка покосившуюся телефонную будку. Дай Бог, чтобы телефон работал, мысленно взмолился Беккер. Двигаясь к будке, он нащупывал в кармане деньги. Нашлось 75 песет никелевыми монетками, сдача от поездки в такси, - достаточно для двух местных звонков.

Кадр казался неестественно вытянутым по вертикали и неустойчивым, как бывает при дрожащем объективе, - это было результатом удаления кадров, процесса, сокращающего видеозапись вдвое и экономящего время. Объектив, скользнув по огромной площади, показал полукруглый вход в севильский парк Аюнтамьенто. На переднем плане возникли деревья. Парк был пуст. - Фильтр Х-одиннадцать уничтожен, - сообщил техник.

    Biological control is the use of non-chemical and environmentally friendly methods of controlling insect pests and diseases by the action of natural control agents. In recent decades, the increase use of biological control is due to its safety, species specific and long-term action on the target pests.
