Which insect, known as Tetranychus turkestani, is particularly harmful to strawberries?

Tetranychus turkestani is more widely recognized as the Strawberry spider mite, making this the correct answer. This particular mite is known to be a significant pest for strawberries, where it feeds on the plant's sap. Its feeding leads to stippling on the leaves, which can impede photosynthesis and overall plant health, ultimately affecting fruit production and quality.

In contrast, while the twospotted spider mite (another species of Tetranychus) is also known to affect a variety of crops, it is not specifically tied to strawberries in the same way as the Strawberry spider mite. Lygus bugs are known pests of many crops, including strawberries, but they are plant-sucking insects that behave differently from spider mites. Corn leaf aphids primarily affect corn, and while they could occasionally be found in other crops, they are not a primary concern for strawberry plants. Therefore, the identification of Tetranychus turkestani as the Strawberry spider mite accurately reflects its specific impact on strawberry crops.
