What distinguishes passive traps from active traps?

1. Passive traps contain lures to attract pests

2. Passive traps do not use a lure

3. Active traps are more effective than passive traps

4. Active traps only catch flying insects

The correct answer is: Passive traps do not use a lure

The distinguishing factor between passive traps and active traps lies in their design and functionality concerning attracting pests. Passive traps are characterized by their lack of a lure. They rely on the natural behavior of insects, such as movement or specific environmental cues, to capture them without the use of additional attractants. This type of trap is effective for monitoring pest populations and can be used in various settings without the need for bait or lures. In contrast, active traps typically involve some form of bait or lure that attracts pests, making them actively seek out these traps. While active traps can be effective, the essential characteristic that sets passive traps apart is their lack of any attractant, which simplifies their use and maintenance in certain situations. The other options introduce concepts that do not directly address the core distinction of design between these two categories of traps, such as the effectiveness or specific targets of active traps, which are not inherently related to the definition of passive traps.
