Vertebrates, invertebrates, especially important harmful or beneficial organisms.
6.4.3 testing include. the number of plants and their survey of non-target species population dynamics of insect-resistant transgenic control experiment Tanaka
Changes compared non-target species diversity community, evenness and dominant concentration index, analysis of transgenic insect-resistant
Due to the impact of plants on non-target organisms population and its related ecosystem functions.
Transgenic insect-resistant cotton, maize and rice growing site and its surroundings on the ground some non-target organisms Communities
Affect the test in accordance with this standard, and with reference to the Ministry of Agriculture Bulletin No. 953 -12.4-2007, the Ministry of Agriculture Bulletin No. 953 -10.4-
2007 and the Ministry of Agriculture Bulletin No. 953 -8.4-2007 execution.
6.4.4 under conditions of open design insect-resistant transgenic plant field trials on the impact of non-target organisms, should comply with the following principles
then.
(1) to the parent plant or the local ordinary non-transgenic varieties as a negative control, insect-resistant transgenic plants with the alternative of
Learn pesticides as a positive control;
(2) the test location for a typical habitat insect-resistant transgenic plants, and there is a need to investigate the non-target organisms;
(3) Factors scale test of time, management measures should simulate the actual growth of insect-resistant transgenic plants as much as possible and
Planting patterns.
(4) insect-resistant transgenic plants to control and test should have similar natural conditions, and should be maintained between each test ground
Holding a sufficient distance to avoid mutual interference of each test organism.
(5) test should normally be for three consecutive years or three growing seasons.
7 gene drift detector
7.1 determine the genetic drift objects
In the natural environment to insect-resistant transgenic plants grown in and around, the investigation may be the target species genetic drift
(Hereinafter referred to as "genetic drift target species"), including the insect-resistant transgenic plants parent plants, local non-transgenic
Varieties or wild species.
If insect-resistant transgenic plant cultivation area and its surroundings without genetic drift target species, especially with Insect Resistance
GM plants closer genetic relationship of wild relatives and weed species, genetic drift detection can be terminated.
