“…Resistance to the oxime carbamates thiodicarb and methomyl has been recorded a number of times in populations of H. virescens from Louisiana, Mississippi, Texas and Arkansas (Sparks 1981;Elzen et al 1992;Martin et al 1992Sparks et al 1993;, and also in populations from Mexico (Roush & Wolfenbarger 1985). Thiodicarb and methomyl are the carbamates most widely used against H. armigera in Australia.…”

“…The ¢rst reports of signi¢cant resistance appeared in 1985 in west Texas (Plapp & Campanhola 1986) and these were quickly followed by a range of similar ¢ndings throughout the cotton-belt states of the southern USA, including Alabama (Mullins et al 1991), Arkansas (Plapp et al 1987(Plapp et al , 1990), Louisiana (Leonard et al 1988;Plapp et al 1990;, Mississippi (Luttrell et al 1987;Plapp et al 1990;Elzen et al 1992;Ernst & Dittrich 1992), Oklahoma (Plapp et al 1990) and Texas (Plapp et al 1987(Plapp et al , 1990). In many cases this resulted in considerable cross-resistance between pyrethroids and this was thought to imply the presence of a target-site mechanism of resistance (Martin et al 1992;Graves et al 1993;Sparks et al 1993). Because a complete loss of pyrethroids was feared, resistance monitoring programmes were instituted (Plapp et al 1987), and management plans organized in Texas and the mid-south in an e¡ort to provide pyrethroid-free windows during the cotton-growing season (Sparks et al 1993).…”

The status of resistance to organophosphate, carbamate, cyclodiene and pyrethroid insecticides in the heliothine Lepidoptera is reviewed. In particular, resistance in the tobacco budworm, Heliothis virescens, and the corn earworm, Helicoverpa zea, from the New World, and the cotton bollworm, Helicoverpa armigera, from the Old World, are considered in detail. Particular emphasis has been placed on resistance to the most widely used of these insecticide groups, the pyrethroids. In each case, the incidence and current status of resistance are considered before a detailed view of the mechanisms of resistance is given. Controversial issues regarding the nature of mechanisms of resistance to pyrethroid insecticides are discussed. The implications for resistance management are considered.

“…In the Midsouth region of the United States where most of this genetically engineered cotton will be grown, the major pest targeted for control by the Bt toxin is H. virescens. This lepidopteran species has evolved resistance to almost all registered conventional insecticides (19), so farmers have a strong incentive to use engineered plants that produce the Bt toxin.…”

The risk of rapid pest adaptation to an insecticide is highly dependent on the initial frequency of resistance alleles in field populations. Because we have lacked empirical estimates of these frequencies, population-genetic models of resistance evolution have relied on a wide range of theoretical estimates. The recent commercialization of genetically engineered cotton that constitutively produces an insecticidal protein derived from the biocontrol agent, Bacillus thuringiensis (Bt) has raised concern that we lack data needed to quantify the risk of insect pests such as Heliothis virescens rapidly adapting to this ecologically valuable class of toxins. By individually mating over 2,000 male H. virescens moths collected in four states to females of a Bt toxin-resistant laboratory strain, and screening F 1 and F 2 offspring for tolerance of the toxic protein, we were able to directly estimate the field frequency of alleles for resistance as 1.5 ؋ 10 ؊3 . This high initial frequency underscores the need for caution in deploying transgenic cotton to control insect pests. Our single-pair mating technique greatly increases the efficiency of detecting recessive resistance alleles. Because alleles that decrease target site sensitivity to Bt toxins and other insecticides are often recessive, this technique could be useful in estimating resistance allele frequencies in other insects exposed to transgenic insecticidal crops or conventional insecticides.

“…Additionally, several species of insects have developed resistance to foliar insecticides. They include tobacco thrips, Frankliniella fusca (Hinds) (Huseth et al, 2016); tarnished plant bug, Lygus lineolaris (Palisot de Beauvois) (Snodgrass 1996); bollworm, Helicoverpa zea (Boddie) (Graves et al, 1963,); and tobacco budworm, Heliothis virescens (F.) (Brown et al, 1998;Martin et al, 1995). Of those species, the tarnished plant bug is the most important insect pest of cotton grown in the mid-southern states of Arkansas, Louisiana, Mississippi, Missouri, and Tennessee (Williams, 2016).…”

Tarnished plant bug, Lygus lineolaris (Palisot de Beauvois), is the most important insect pest of cotton, Gossypium hirsutum L., in the states of Arkansas, Louisiana, Mississippi, Tennessee, and Missouri. Foliar insecticide sprays are an important tactic within an integrated pest management (IPM) program for this pest which occurs from early flower bud development to cut out, a stage where the plant has reached the capacity for supporting fruiting positions and equivalent to when there are five nodes above the uppermost first position white flower (NAWF 5). Currently, NAWF and heat unit accumulation monitoring is limited, resulting in a need for a more simplified insecticide termination method that has the potential for wider adoption. Experiments were conducted in 2015 and 2016 in the previously mentioned states to determine when to terminate insecticide sprays for tarnished plant bug based on week of flowering. Treatments included terminating sprays after the second through sixth weeks of flowering, a season-long control, and an untreated control. In general, insecticides reduced densities of tarnished plant bugs in the sprayed treatments. When analyzed by location, treatments that resulted in cotton yields similar to the season-long control ranged from weeks two through five of flowering. These data suggest that treatments can be terminated after the fifth week of flowering. Data from this study indicate applications terminated after the fifth week of flowering would be similar to the current recommended termination timing of NAWF 5 plus 350 heat units. Results from this experiment will be used to better define a simplified IPM strategy for tarnished plant bug in cotton.
