“…Planting date and cotton cultivar selection can impact tarnished plant bug management. In a previous study, a later maturing full season variety at later planting dates (after mid-May) required more insecticide applications compared to a short season cotton variety planted at earlier dates ( Adams et al 2013 ). Cotton varieties with dense pubescence also can experience lower numbers of tarnished plant bug and require fewer foliar sprays compared to a smooth leaf variety ( Wood et al 2017 ).…”

The tarnished plant bug, Lygus lineolaris (Palisot de Beauvois), is an important pest of cotton in many areas of the southern United States. An experiment was conducted at two locations in Mississippi during 2016 and 2017 to evaluate action thresholds for tarnished plant bug on a novel Bacillus thuringiensis cotton that expresses the Cry51Aa2.834_16 toxin. Treatments included the current action threshold, a 2× threshold, and treatments where insecticides were only applied during the early season (preflower) or only during late season (during flowering) based on the current action thresholds. These were compared to an untreated control and a weekly insecticide use regime that received weekly insecticide sprays. All treatments were imposed on both Bt Cry1Aa2.834_16 cotton and a nontraited cotton. The Bt Cry1Aa2.834_16 trait reduced the number of tarnished plant bugs and injury, and improved yields compared to nontraited cotton. For all spray treatments except the weekly insecticide use regime, yields were greater for the Bt Cry51Aa2.834_16 cotton than the nontraited cotton. In terms of thresholds, Bt Cry1Aa2.834_16 cotton sprayed based on current action thresholds resulted in similar yields to the weekly insecticide use regime of both cotton types. In contrast, the 2× threshold resulted in lower yields than the current threshold for both cotton types. Though thresholds intermediate to the currently recommended action threshold and the 2× threshold were not tested, these data suggest that currently recommended action thresholds appear appropriate for Bt Cry51Aa2.834_16 cotton. These results suggest that this trait will be an important component of current IPM programs in cotton where tarnished plant bug is an important pest.

“…Earlier planting of cotton reduced the chance of infestation by late season insect pests (Pettigrew 2002;Adams et al 2013). Also, planting dates and planting pattern are considered important factors for increasing seed cotton yield per unit area (Din et al 2004;Dong et al 2006 andBarradas andLopez-Bellido 2009).…”

Relationship between cotton planting date and two bollworms associated with their natural enemies

Background Cotton is the most widespread, profitable non-food crop in the world. Egypt is one of the greatest countries in producing cotton (Gossypium hirsutum L.) in the world. Many pests attacked cotton which reduced the quality and quantity of the cotton yield such as pink bollworm (Pectinophora gossypiella) (Lepidoptera: Gelechiidae) and the spiny bollworm (Earias insulana) (Lepidoptera: Noctuidae). Results The insect infestation increased significantly by delaying planting date. The fewest numbers of pests attacked cotton recorded in the earliest planting date (March 23rd) with highest weight of cotton yield. The results showed that the mean rates of infestation with pink bollworm were (2.11, 3.5, 2.33 individuals/boll) for March 23rd, April 17th and May 6th, respectively, while the mean rates of infestation with bollworm were (1.60, 2.79, 1.67 individuals/boll) for March 23rd, April 17th and May 6th, respectively. Conclusion It was concluded that planting cotton as early as on March 23rd reduces the rate of infestation of E. insulana and P. gossypiella and increases the population of its natural enemies as well. Then, it is resulting a significant increase in the quality and quantity of the yield of cotton.

“…More recent research has re-evaluated the impact of those factors on L. lineolaris management in cotton using natural infestations of L. lineolaris . Adams et al [ 150 ] planted two cotton cultivars (early maturing and late maturing) at four planting dates (mid-April, early-May, mid-May, and early-June). Percent yield loss from L. lineolaris was greater for the late maturing variety than the early maturing variety, and for the early-June planting date compared to all other planting dates.…”

“…Percent yield loss from L. lineolaris was greater for the late maturing variety than the early maturing variety, and for the early-June planting date compared to all other planting dates. Both planting date and cultivar affected the number of foliar insecticide sprays needed to maintain L. lineolaris densities below the economic threshold [ 150 ]. In general, later planting dates required more insecticide applications than earlier planting dates.…”

The tarnished plant bug, Lygus lineolaris (Palisot de Beauvois), (Hemiptera: Miridae) is considered the most damaging pest of cotton (Gossypium hirsutum L.) in the mid-southern United States, although it is established throughout the United States, southern Canada, and northern Mexico. The introduction of transgenic crops for the control of moths in the Heliothine complex and eradication of the boll weevil, Anthonomus grandis, from much of the United States led to greatly reduced pesticide use in cotton fields, which allowed L. lineolaris to emerge as a new primary pest of cotton in the mid-southern United States. Since the publication of a review by Layton (2000) on damage caused by Lygus lineolaris, many new studies have been published on the changes in host range, population dynamics, sampling methods and thresholds, cultural practices, sex pheromones and attractant blends, novel pesticides and insecticide resistance mechanisms, olfactory and feeding behaviors, introduction of biological control agents, host-plant resistance mechanisms, and new molecular and genetic tools for integrated pest management of Lygus species in cotton and other important crops. Here, we review and discuss the latest developments in L. lineolaris research in the last two decades.
