It provides a comparison of the benefits of internal and external approaches to pest control, and highlights prevention techniques designed to control pests.
In the long-run it leads to a reduction in resilience to external threats such as pests, disease and adverse weather events and a reduced capacity to erosion control and nutrient cycle, etc., most importantly leading to lower productivity of bamboo forests (Yiping and Henley 2010; Song et al. 2011).
And in large measures the agricultural industry has been able to accomplish this through the widespread use of pesticides and genetically modified crops that are resistant to pests and other external factors.
There are two approaches to pest control: internal and external.
This is both cruel to the hamsters, who have not learned external living skills, and has a pest creation potential that can disturb the local ecosystem.
External challenges include increasing needs to manage pests (pathogens, animal pests and weeds) due to climate change, evolution of pesticide resistance as well as virulence matching host resistance.
However, most respondents indicated that livelihood activities were influenced by a number of internal and external factors, most importantly low rainfall, pests, and the lack of inputs and markets.
Integrated pest management (IPM) is facing both external and internal challenges.
An important reason for the decline in OP insecticide application to corn, cotton and potatoes was the adoption of crops genetically modified to produce Bt toxin, which repels targeted insect pests, thus reducing the need for external insecticides.
The complexity of designing effective pest management strategies, which rely less heavily on the use of conventional pesticides, is another external challenge.
