It is considered a highly polyphagous species and feeds on over half of all commercially grown crop plants, but favors cotton, alfalfa, beans, stone fruits, and conifer seedlings.

Adults grow up to 6.5 mm in length, and are brown with accents of yellow, orange or red, with a light-colored "V" on the back (dorsal).

[7] Researchers used pollen grains as indicators of food sources being utilized by L. lineolaris as well as their movement between wild host plant habitats and cropping areas.

The pollen grains further indicated that L. lineolaris spent time away from crops and instead were found on plants that were in wet or disturbed sites.

[10] Researchers have conducted experiments involving odourant-binding proteins (OBP) which allow for perception of odours in L. lineolaris and other insect groups.

A study involved transcriptomics in order to investigate olfaction in L. lineolaris to reduce its harmful impacts on commercial crops.

The visual system in L. lineolaris is not heavily investigated although it could provide insight into the different stimuli that allow these insects to discriminate food sources.

A study investigated whether L. lineolaris adults showed distinctive visual responses to two different colours of sticky traps.

[12] Other traps involve using a bed sheet tied with a nylon rope around two metal poles to capture adult TPB.

[2] Although traps are widely used to collect TPB, sweep nets are also effective in capturing these insects due their small size and tendency to rest on plant leaves.

Another study used sweep nets to capture L. lineolaris individuals off wild host plants while also using aspirators to place them into collection containers.

[13] The results obtained from the study indicated that the first four weeks of flowering were the most effective in controlling for L. lineolaris because this is when most cotton yield loss was observed.

Neonicotinoids are a family of insecticides which cause interference and blockage of the nicotinergic pathway in the central nervous system of insects.

A similar study investigating L. lineolaris from two geographical regions in terms of differing developmental time, fecundity, hatch rate, and survivorship was conducted.

[6] Although there were no differences found in the development time, fecundity, hatch rate, and survivorship of the L. lineolaris captured from the Delta and Hills regions, the researchers suggest that the larger area of the Delta region might have caused the L. lineolaris population to be subjected to more insecticides thereby having more resistance and causing more pest-related issues.

[6] In the mid 1980s, parasitic wasps, Peristenus digoneutis, were imported from France and their establishment[clarification needed] in the northeastern United States has resulted in reduction of crop losses to the TPB of up to 63% in alfalfa and 65% in apples.

[2] Rainfall can be classified as a form of mechanical control of L. lineolaris because rain drops may knock individuals off plants and cause a reduction in their survival.
