Transgenic Virus Resistant Crops
Crops with genetic resistance to viruses incorporated into their DNA, reducing the need for chemical control methods. High effectiveness in preventing viral infections in crops.
Trichogramma Wasps
Parasitic wasps that lay eggs inside pest insect eggs, providing a biological control option. Effectiveness can be influenced by climate and availability of host eggs.
Crop Rotation
The practice of alternating the species or varieties of crops grown on a particular piece of land from one season or year to the next. It disrupts pest life cycles and can reduce pest pressure.
Bioherbicides
Biological agents that specifically target weed species, offering alternatives to chemical herbicides. Effectiveness is highly specific to the target weed and environment conditions.
Endophytic Microorganisms
Microorganisms that live inside plant tissues and can provide protection against insect pests. The effectiveness varies but offers an environmentally friendly pest control method.
RNA Interference (RNAi)
A method that utilizes double-stranded RNA to silence specific genes in pests, resulting in their death or incapacitation. Selectively effective on targeted pests with reduced environmental impact.
Herbicide-Resistant Crops
Crops engineered for resistance to specific herbicides, allowing farmers to control weed pests without harming the crop. Highly effective for weed management but may lead to herbicide resistance.
Biological Control Agents
Use of natural predators, parasites, or pathogens to manage pest populations. Effectiveness varies depending on agent and environment, but can provide long-term control.
Plant-Incorporated Protectants (PIPs)
Pesticides that plants produce from genetic material that has been added to the plant. Provide continuous protection against pests and reduce the need for topical pesticides.
Push-Pull Strategy
An agricultural strategy that combines repellent 'push' plants and attractive 'pull' plants to manage pests. Environmental friendly and can be cost-effective, but its effectiveness can vary with local conditions.
Integrated Pest Management (IPM)
A systematic approach combining biological, cultural, physical, and chemical tools in a way that minimizes economic, health, and environmental risks. Effectiveness depends on correct implementation.
Phytase-Expressing Transgenic Plants
Crops engineered to express phytase, improving nutrient availability and possibly deterring certain pests by affecting their digestion. Moderate effectiveness with indirect pest control benefits.
Biopesticides
Pesticides derived from natural materials such as animals, plants, bacteria, and certain minerals. Generally less toxic than conventional pesticides and target-specific.
Genetic Pest Management
Methods that involve manipulating the genetics of pests to control their populations, such as gene drive systems. Their effectiveness and ethical considerations are currently under research.
Sterile Insect Technique (SIT)
A method of pest control that involves releasing sterile males into the wild population to reduce breeding and subsequent pest population. Effectiveness varies but can lead to substantial pest population decline.
Entomopathogenic Fungi
Fungi that act as pathogens to insects, suppressing pest populations. Their effectiveness can vary with environmental conditions and application methods.
Bt Crops
Crops genetically engineered to produce Bacillus thuringiensis (Bt) toxins, which are lethal to certain insect pests. High effectiveness against target pests with minimal impact on non-target species.
Nucleopolyhedroviruses (NPVs)
Viruses that are specific to insect pests and are used as biological control agents. They are highly specific and have minimal impact on non-target species or the environment.
