What pest is linked to cotton and corn, known as Tetranychus pacificus?

The correct answer is the Pacific spider mite, which is scientifically known as Tetranychus pacificus. This pest is recognized for its significant impact on agricultural crops, particularly cotton and corn. The Pacific spider mite is known to thrive in warm climates and can cause considerable damage by feeding on the plant's sap, leading to leaf discoloration, stunted growth, and overall reduced crop yield.

The other options refer to different types of spider mites that may have varying geographical distributions or host plants. The twospotted spider mite and carmine spider mite are also common agricultural pests, but they are not specifically linked to cotton and corn in the same way as the Pacific spider mite. The strawberry spider mite primarily affects strawberry plants, making it less relevant in the context of cotton and corn. Understanding the specific characteristics and impacts of Tetranychus pacificus helps in developing targeted pest management strategies in agricultural practices.
