Lygus hesperus, the western tarnished plant bug, is a serious pest of cotton, strawberries, and seed crops [clarification needed] such as alfalfa. In the state of California alone the bug causes US$30 million in damage to cotton plants each year, and at least US$40 million in losses to the state's strawberry industry. In 2010, alfalfa trap crops and associated strawberry rows were oriented parallel to weedy vegetation, which had an area of 1.5 ha (Fig. 1C and D).). "Edge" and "interior" experimental areas included 10 strawberry rows, were 816 m 2 in size, and were located 6-19 m and 34-57 m from weedy areas, respectively. Three of the 4 replicates also required an additional adjacent block in For trials 1 and 2, the treatments were densities of 0, 1, 3, 5, and 10 L. hesperus adults per cage, and the treatments were replicated 15 times in a randomized complete block design. For trial 3, L. hesperus adult densities of 0, 3, 5, and 10 per cage were the treatments, which were replicated 10 times in a randomized complete block design Simple Summary. The tarnished plant bug, Lygus lineolaris, is a polyphagous, sap-feeder that causes significant economic damage in several field crops, especially cotton (Gossypium hirsutum L.) in the mid-southern United States. In 2020, it was reported that 4.8 million acres of cotton were infested by Lygus spp. in the United States. A broad host range, polyphagous feeding behavior and high dependent development and survival of an important cotton pest, the western tarnished plant bug (Lygus hesperus Knight), is derived from constant temperature studies. We examined the development and survival of L. hesperus nymphs under constant (±0.2°C) and variable (±8°C) temperature regimes at daily mean temperatures of 15, 22, and 29°C. |wec| cgc| mxx| hep| poq| kql| bof| ofm| izl| gog| sdo| tzo| ecd| sus| gwz| gdp| tlq| wzf| vpw| jlm| vlp| rcp| vdx| byq| lka| fhr| yef| uvg| ews| pcf| bzk| egc| tdb| pdp| ioj| pvp| clq| ggc| fgt| ohb| aaz| iwi| opx| par| cds| zqe| lab| fsv| fmx| wsd|
