In 2015, Oxitec developed GM-diamondback moths which produce non-viable female larvae to control populations able to develop resistance to insecticides. The GM-insects were initially placed in cages for field trials. Earlier, the moth was the first crop pest to evolve resistance to DDT [27] and eventually became resistant to 45 other ...
Biological control or biocontrol is a method of controlling pests, whether pest animals such as insects and mites, weeds, or pathogens affecting animals or plants by using other organisms. [1] It relies on predation , parasitism , herbivory , or other natural mechanisms, but typically also involves an active human management role.
Oxitec is a British biotechnology company that develops genetically modified insects [1] in order to improve public health and food security through insect control. The insects act as biological insecticides. Insects are controlled without the use of chemical insecticides.
In 1972–1973, Philippines was beset by rice production shortfalls resulting from the series of typhoons and floods and fertilizer shortages spawned by the oil crisis.The resulting fourfold drop in rice production prompted the government to directly intervene in the operations of the fertilizer industry through the issuance of Presidential Decree (P.D.)

It was originally intended as a protein source for farmers' diet and was also kept as an aquarium pet. It is regarded as a crop pest in rice cultivation. [8] [9] Red-eared slider: Trachemys ...
Bt cotton was created through the addition of genes encoding toxin crystals in the Cry group of endotoxin. [1] When insects attack and eat the cotton plant the Cry toxins or crystal protein are dissolved due to the high pH level of the insect's stomach.
Slow action speed (thus making them unsuitable if a pest outbreak is an immediate threat) Variable efficacy due to the influences of various factors (since some biopesticides are living organisms, which bring about pest/pathogen control by multiplying within or nearby the target pest/pathogen)
In 2014 the global value of biotech seed was US$15.7 billion; US$11.3 billion (72%) was in industrial countries and US$4.4 billion (28%) was in the developing countries. [89] In 2009, Monsanto had $7.3 billion in sales of seeds and from licensing its technology; DuPont, through its Pioneer subsidiary, was the next biggest company in that market ...
