“…Cotton stalk destruction after harvest is a very important strategy of the integrated pest management (Lima et al, 2013;Grigolli et al, 2015). After harvest, crop residues and stalks can be eliminated by soil tillage implements such as plow and plowing harrow (Bianchini & Borges, 2013;Ribeiro et al, 2015;Sofiatti et al, 2015), although devices have been developed to improve the operational capacity of the destruction and promote minimum soil mobilization (Sofiatti et al, 2015).…”

Cotton stalk regrowth must be controlled after harvest to ensure the phytosanitary quality and sustainability of cotton farming systems. Mechanical destruction generally does not conform to the no-tillage system, and the control of cotton stalk regrowth by herbicides is little studied in Brazil. The objective of this study was to evaluate the efficiency of herbicides to control glyphosate-resistant transgenic cotton stalk regrowth. The study was conducted in three environments of the Brazilian Cerrado region, two in Santa Helena de Goiás (SHGO), during 2013 and 2014, and one in Luís Eduardo Magalhães (LEM-BA) in 2014. In each of the three environments, the experiment was carried out in a randomized complete block with four replications. Each experiment consisted of different combinations of herbicides and one untreated control. Cotton stalk regrowth was influenced by the three environments. Two sequential 2,4-D amine applications, each with 1,000 g ha-1 of acid equivalent, resulted in better cotton stalk destruction, albeit with 4.9, 16.9 and 36.9% of cotton stalk regrowth in SHGO 2013 and 2014, and LEM-BA 2014, respectively. A single application of 2,4-D amine and a 2,4-D amine spraying followed by the application of carfentrazone-ethyl, paraquat, saflufenacil, paraquat + diuron or glufosinate-ammonium are not effective to control glyphosate-resistant transgenic cotton stalk regrowth. The best destruction of cotton stalk regrowth occurs with two sequential applications of 2,4-D amine.

“…These authors indicated that few regrowths were present in the surveyed area as the reason that weevils were in the refuge and were attracted to the traps containing Fig 2 (continued) pheromone. Furthermore, Grigolli et al (2015) found boll weevil colonizing and reproducing successfully on cotton regrowths off-season in the Southeast region of Brazil (Jaboticabal, São Paulo). Silva et al (2018) also found active boll weevils (larvae and adults) in the Centralwest, on cotton regrowth from different areas of the Cerrado (Mato Grosso do Sul).…”

“…Thus, controlling boll weevil requires attention during the flowering-fruiting stages of cotton plants, which is when plants become susceptible to both adult feeding and reproduction, causing direct crop loss. Data from literature also report about plant colonization (Showler 2006, Spurgeon 2016) and maintenance in the field (Fernandes et al 2001, Grigolli et al 2015, Neves et al 2018, Silva et al 2018, but information is lacking about how commercial cotton fields are colonized by boll weevil as a function of the crop phenology and their bordering vegetation in the Brazilian Cerrado. The knowledge about the spatial distribution of the boll weevil occurrence might help control decisions such as delimiting the area to deploy the BWACT and areas to be treated with insecticides (i.e., field borders instead of spraying the whole field).…”

The departure and arrival of boll weevil in cotton fields have fostered major control decisions against this pest over time. Field colonization and distribution of boll weevil were evaluated using cotton fields from 93.7 to 154 ha each, located in Serra da Petrovina and Campo Verde, both in the Cerrado biome of Mato Grosso State, Brazil, as a function of cotton field bordering vegetation and crop phenology. The monitoring of adult weevils was carried out using traps containing sex and aggregation pheromone. The traps were set up considering the four coordinates of the field, bordering vegetation, and distances from the field margin. Six traps were set in each direction with three representing the field margin (0 m, 60 m, and 120 m from the borderline) and the other three set up equidistant from the center of the field (> 200 m). Traps were evaluated weekly beginning 10 days after plant emergence (DAE) throughout the cotton phenology until harvesting. Boll weevils were caught in the first evaluation 10 DAE, irrespective of the vegetation bordering the cotton field and distance of trap from field margin. The average weevils per trap was relatively low throughout the crop development but increased significantly through the maturation and harvesting periods. Furthermore, the bordering vegetation was not the only determinant factor for boll weevil colonization and distribution throughout the cotton field. Based on these data, boll weevil exhibited early colonization, already occurring beyond the border of the field.

“…One of the strategies for the management of boll weevil populations is the destruction of the cotton stalks during the fallow period; it is considered useful. If this is not carried out, under ideal environmental conditions, cotton plants can regrow, and consequently produce reproductive structures, such as buds, flowers, and fruits, therefore, hosting the species A. grandis during the off-season (Lu et al, 2010;Bianchini & Borges, 2013;Grigolli et al, 2015).…”

“…In Brazil, there are no studies on the composition of insect pests during the fallow period in the cotton crop residues. Most of the studies deal with the considered most efficient cotton stalk destruction methods (Bianchini & Borges, 2013); the crop residue destruction methods and survival of the boll weevil (Ribeiro et al, 2015); and population dynamics of the boll weevil (Grigolli et al, 2015;Pires et al, 2017) and A. gossypii (Izeppi et al, 2011) in the crop residue during the off-season.…”

The objective of this work was to analyze the faunistic composition of the insect pests that occur during the fallow period in cotton (Gossypium hirsutum) crop residues in the state of Mato Grosso do Sul, Brazil. The study sites were the municipalities of Alcinópolis, Chapadão do Sul, Costa Rica, Aral Moreira, Dourados, and Sidrolândia. A sampling design with two replicates per municipality was used. Each replicate comprised 100 random points, and each point corresponded to a cotton plant that was entirely inspected, to count the insect pests on it. The obtained fauna was analyzed and a rarefaction curve of the species was generated. During the evaluation period, a total of 23 species were recorded in the cotton crop residue, and the most frequent and abundant were Bemisia tabaci, Aphis gossypii, Frankliniella schultzei, and Anthonomus grandis. The caterpillars were predominantly found on the non-Bt cotton crops in Dourados, and Chapadão do Sul was the municipality that exhibited the greatest species diversity. Despite being mandatory, the destruction of cotton stalks during the fallow period was not able to completely eliminate the insect pests during the study period; among these insect pests, A. grandis stands out, a species that affects the dynamics of cotton pest control.
