Non-insecticidal control strategies using entomopathogens, nematodes, and endophytes provide sustainable and safer alternatives for managing crop pests. This study investigated the potential of different fungal endophytes, specifically strains, in colonizing cotton plants and their efficacy against tarnished plant bug, . The effect of endophytes on plant growth parameters and cotton yield were measured during different plant growth stages.

During early spring, managing the field edges with weeds and other wild hosts is important in preventing early-season infestations of in cotton to prevent damage to the squares and other fruiting structures. Scouting fields for is time- and labor-intensive, and end-user variability associated with field sampling can lead to inaccuracies.

(Hemiptera: Plataspidae) nymphs and adults that were exposed to two native Beauveria bassiana isolates (Previously codified as NI8 and KUDSC strains) at four concentrations. The greatest reduction in survival and mortality was observed primarily on or after 10 d post-exposure to B.

The introduction of transgenic crops for the control of moths in the complex and eradication of the boll weevil, , from much of the United States led to greatly reduced pesticide use in cotton fields, which allowed to emerge as a new primary pest of cotton in the mid-southern United States.

Serratia marcescens was originally isolated from bolls infested with verde plant bug in south Texas, and a Rifampicin resistant S. marcescens strain was used in transmission and retention experiments.

In a 2-yr mark-release-observe experiment, over 500 adult green stink bugs, Chinavia hilaris (Say) (Hemiptera: Pentatomidae), were used to test for variation in nocturnal and diurnal insect distribution patterns on cotton. Field-collected stink bugs were marked or unmarked with nontoxic fluorescent sharpie markers, released, and monitored in cotton fields at peak bloom.

Field-collected adult bugs were used to infest cotton plants previously maintained free of insect injury. Plants caged in groups of four were infested at mid-bloom and late-bloom for 7 d with four insect densities: 0 (control), 0.
