Insect Repellent Effect Study
To ensure the healthy state of important livestock species, producers need to use safe and effective repellent products to eliminate the effects of various pests on them. However, traditional repellent products are plagued with issues such as resistance and cross-tolerance, making repellent ingredients sourced from plant extracts the preferred choice. Lifeasible helps you research plant-derived repellents through activity testing, formulation development, and other services and makes them more quickly available for use in areas such as livestock management and animal disease control.
Our Services
We use solvent extraction, water vapour distillation, ultrasonic extraction, and sublimation to extract the effective components of plant anthelmintic, and then through the determination of anthelmintic activity can screen out the better anthelmintic activity of plant extracts.
- According to the feeding amount, we can determine the refusal activity of plant extracts on pests.
- We can determine the growth inhibitory effect of plant extracts on pests based on the change in body weight of test insects.
- The toxicological activity of the plant extracts against the pests was determined by the maceration method.
- The poisoning activity of the plant extracts against the pests was determined by the spot-drip method.
- We determined the fumigant activity of the plant extracts against the pests using the wide-mouth bottle closed fumigation method.
- We used leaf added method for the determination of the gastric toxicity activity of plant extracts against pests.
- We used an olfactometer for the determination of the repellent activity of plant extracts against pests.
- Formulation services
- Preparation of microcapsules
- Determination of the optimal ratio of ingredients
- Determination of surface oil and embedding rate
- Determination of biological activity (non-selective and selective experiments)
If the insect-repellent active substances in plant extracts are sensitive to light and heat, they will decompose easily when exposed to light and heat, which will seriously limit their application. Therefore, we can encapsulate them in microcapsules according to your research needs, which can make the active substances released slowly through the semi-closed capsule wall, keep the stability of the main ingredients, and prolong their active time.
For other types of formulation development, such as drops, sprays, essential oils, etc., you need to first provide your target plant extracts, which will be evaluated to determine the best formulation solution.
Why Choose Us?
The plant extract is rich in natural active ingredients with excellent anthelmintic and many other effects. It can kill existing intestinal parasites and prevent new parasitic infections without causing resistance and cross-resistance of pathogenic microorganisms, which greatly improves its safety and value of use. Lifeasible can assist you in the improvement and development of plant-based insect repellents through a variety of activity assays. Please feel free to contact us to submit your requirements.
