“…This higher mortality rate in the second and third instars partially agrees with the results obtained for the same species, but fed with Chorisia speciosa St. Hil. (Bombacaceae) seeds and with the IAC 22 cotton cultivar with a low oil seed content (Almeida & Gonçalves, 2007), as well as for Dysdercus peruvianus Guérin-Méneville fed with seeds of this same cotton cultivar (Milano et al, 1999).…”

“…However, the crop can be attacked by several pests, among which stand out cotton stainers of the genus Dysdercus (Pyrrhocoridae), which are important seed-sucking bugs in several countries around the world (Shah, 2014;Saeed et al, 2016;Shafiq et al, 2020). Dysdercus maurus Distant, 1901 (Heteroptera: Pyrrhocoridae) is one of the most competitive species for food resources, with a wide variety of host plants and geographical distribution (Almeida & Gonçalves, 2007). This stinkbug is one of the most destructive cotton pests in Brazil (Jorge & Lomônaco, 2009), causing either direct damage, by destroying cotton boll tissue and mature seeds, making them unviable and wrinkled, with weight loss and reduced oil content, or indirect damage, by the inoculation of opportunistic microorganisms (bacteria and fungi), mainly staining cotton fibers (Salem et al, 2013;Sontakke et al, 2013;Azher et al, 2019).…”

The objective of this work was to determine the biological and morphological parameters of Dysdercus maurus fed with cotton (Gossypium hirsutum) seeds with a high or low oil content, as well as to identify genotypes to be used in breeding programs as sources of resistance to this stink bug. The development, survival, and reproduction of the cotton stainer bug were determined in a completely randomized experimental design. The treatments consisted of the insect nymphs being feed with cotton seeds of the CNPA 2001-5581 (high oil content) or CNPA 2001-5087 (low content) genetic line. Survival, weight, and morphological parameters of the bug were determined. The survival of second- and third-instar nymphs and of the total nymph stage of D. maurus was lower with cotton seeds with a low oil content. The body length and head width of D. maurus adults were greater, but pronotum length and width were smaller and the females heavier with cotton seeds with a high oil content. Low-oil cotton genotypes can reduce populations of the stainer bug.

“…Outros autores observaram maior riqueza de espécies em áreas com maiores temperaturas (ALBUQUERQUE & DIEHL, 2009), o que não corrobora os presentes resultados, pois a riqueza de espécies de formigas foi maior nos cultivos orgânicos, que tiveram menor temperatura. Temperaturas muito baixas podem reduzir a atividade, a velocidade de desenvolvimento e a reprodução dos insetos (ALMEIDA & GONÇALVES, 2009;ALBUQUERQUE & DIEHL, 2009). Porém temperaturas muito altas e grande incidência de luz solar podem ter o mesmo efeito (ANDERSEN, 2000), o que explica, em parte, a menor riqueza de espécies de formigas nas áreas com maior temperatura.…”

Este trabalho teve como objetivo avaliar a riqueza, a diversidade, a abundância e a composição da fauna de formigas em oito propriedades rurais com cultivo orgânico e oito com cultivo convencional, no município de Paraíba do Sul (RJ). Instalaramse em cada área cultivada 15 armadilhas tipo pitfall para a coleta das formigas. Amostraram-se 48 espécies de formigas no total, pertencentes a sete subfamílias e 23 gêneros. A riqueza nos cultivos convencionais foi de 29, e nos cultivos orgânicos, 38. Os valores médios de riqueza e diversidade de espécies e a abundância média foram maiores nas áreas com cultivo orgânico do que nos cultivos convencionais. O número de espécies cultivadas, a profundidade de cobertura vegetal morta e a temperatura estiveram entre as variáveis que mais afetaram a mirmecofauna. A composição de espécies de formigas variou significativamente entre áreas com cultivo convencional e orgânico (ANOSIM, R = 0,6099, p < 0,01). Os resultados corroboram a realidade de que a prática da agricultura orgânica constitui uma alternativa relevante aos cultivos convencionais, por promover a manutenção da biodiversidade local.

“…This species is responsible for losses of seed weight, seed oil content and for several cotton ball damages produced by bacterial and fungal opportunistic attacks in many Malvaceae species (Almeida et al 1986). According to Nóbrega (1989), this insect displays an elaborated courtship behavior, initiated by the male attempting to laterally approach the female and touching her body with his antennae.…”

This study analyses the role of body size and symmetry in the sexual selection and courtship behavior of Dysdercus maurus Distant. Sexual conflicts signaled by coercive mating, female resistance, and precopulation fights illustrate the mating system. Male-female struggles were observed in all mating attempts. Females tried to reject males by pushing or running and even by vigorously shaking their bodies, in attempts to dislodge the male from their dorsum. In spite of sexual conflicts during courtship, females actively chose their mates based on morphological and behavioral traits. Larger males with more symmetrical tibiae and longer tarsi that are better copula imposers were more successful in sexual competition. Evidence is presented that sexual conflict and female mate choice should not be mutually excluded.
