• B. Quadrat sampling
• C. Transect sampling
• D. Netting

Answer: (A)

The method of applying a low dose of insecticide to the top of a tree is known as canopy fogging. This technique involves using a fogger to create a mist of insecticide that disperses in the upper layers of the forest canopy, effectively targeting pests that reside there. Canopy fogging is particularly useful because many insect pests inhabit areas high in trees, making them difficult to reach with conventional pesticide application methods. By delivering the insecticide in a fog, it ensures that the treatment is evenly distributed and can affect a larger area, reducing the overall amount needed while also minimizing the impact on non-target organisms that might reside lower in the trees or on the ground. The other methods listed, such as quadrat sampling and transect sampling, are ecological techniques used for studying the distribution and abundance of organisms in a given area but are not related to the application of pesticides. Netting refers to capturing organisms for study and also does not pertain to insecticide application. Therefore, canopy fogging is the most appropriate technique for this specific context of applying insecticide to tree tops.
