“…Approximately 200 adults from each locality were collected and taken to the Laboratory of Arthropod Molecular Ecology at the University of São Paulo, USP/ESALQ (Piracicaba, São Paulo, Brazil). The insects were reared and maintained as described by Hickmann et al (2021). In brief, the insects were kept in cages under controlled laboratory conditions (25 ºC, 65% r.h., and L14:D10 light regime), and a natural diet and water were offered ad libitum.…”

“…Two allopatric strains of E. heros occur in Brazil, one prevalent in the south (hereafter SS) and another common in the north/northeast (hereafter NS) . Despite the long period of geographic isolation between the northern and southern strains, these allopatric strains have formed a hybridization zone in central Brazil without a significant reproductive isolation Hickmann et al, 2021). The reunion of two gene pools, without complete reproductive isolation, can mediate evolutionary events through recombination, hybrid vigor, and selection of adaptive alleles in local populations (Gasperi et al, 1991;Wilding et al, 2001;.…”

Assessing matting patterns, chromosome composition, host suitability, and diapause expression of Euschistus strains and speciesBrazil has become a prominent agricultural producer, contributing significantly to the global food supply. Stink bugs of the Pentatomidae family are a group of insects common in Brazil that feed on crops, causing decreased production and quality. Historical and contemporary demographic and adaptive factors associated with agricultural practices are important in determining which arthropods, native or invasive, will positively or negatively impact agroecosystems from a human point of view. For example, the Neotropical brown stink bug, Euschistus heros (Fabricius), a species rarely found in soybean fields until the 1970s, quickly evolved into a major soybean pest in just a few decades. The discovery of two allopatric strains of E. heros in South America, with a secondary contact area in central Brazil, has raised questions about its impact on pest dynamics in Brazil. Furthermore, E. heros has recently become a significant threat to cotton crops. Additionally, several species of Euschistus have been recorded in the Neotropical region on soybeans, but only E. heros has become highly prevalent in soybean fields. This study aimed to investigate the causes of a possible process of pre-zygotic isolation in the asymmetric gene flow between the two strains of E. heros, as well as to characterize the meiotic behavior and satellite DNA dynamics of the two strains of E. heros and their hybrid progeny and compare them with the sister species E. crenator (Fabricius) and E. taurulus Berg. We also characterized the host preference and suitability of the two E. heros strains and their reciprocal hybrids. In addition, we tested soybean and cotton suitability and insecticide susceptibility in three Euschistus species (natural hybrid population of E. heros, E. taurulus, and E. crenator) reported on soybean in Brazil and characterized diapause expression/termination of E. heros (both strains), E. taurulus and E. crenator. Finally, we employed a functional and molecular approach to characterize the transcript profile of E. heros and E. taurulus submitted to different photoperiod conditions, functionally validating the candidate genes related to diapause in E. servus (Say), a Nearctic species. We found that the SS strain is larger and darker, while the NS strain is smaller and has a lighter brown color. In addition, we found that E. heros mates assortatively with larger insects, favoring the SS, and the reciprocal hybrids (NS females mated with SS males) showed a reduced frequency of chiasmas. In addition, satDNAs were accumulated differently, mainly on the Y chromosome, in the two strains of E. heros; however, they did not promote reproductive isolation between the strains. Our bioassays revealed that the SS strain prefers soybeans over cotton, while the NS strain chose soybeans and cotton randomly. The reciprocal hybrid strains (HSN and HNS) behaved similarly to NS, choosing randomly between cotton and soybean...

“…Assim, a presença de estruturação na população pode ser um indicativo de baixo fluxo gênico, mantendo linhagens haplotípicas desiguais, e consequentemente, genótipos distintos, para cada população, que ao longo do tempo pode resultar em especiação (SCHMITT;THAUBRICH, 2008;KERGOAT et al, 2012). Em síntese, as diferentes estruturas podem conter características dispares, em que as populações contendo linhagens genéticas específicas podem apresentar adaptações característica para as diferentes pressões de seleção (SLATKIN, 1987;HICKMANN et al, 2021).…”

Dedico A todos os pesquisadores temporários da ciência, comumente denominados de "estudantes de pós-graduação" que se submetem a fazer pesquisa e ciência com seriedade, apesar do salário tão baixo, sem perspectiva de aumento, sem participação de lucros, sem reconhecimento, sem direitos, sem férias, sem auxílio médico/odontológico, sem cesta-básica, sem auxílio transporte, sem aposentadoria, sem legislação que o auxilie, sem valorização de seu trabalho, sem o apoio da sociedade, e ainda por cima tão criticado nos últimos quatro anos. Dedico a todos esses trabalhadores que com devoção a causa se empenham para gerar conhecimento e avanço científico ao país, como bastidores da economia brasileira, sem os quais não haveria desenvolvimento tecnológico, não haveria agricultura de qualidade no ambiente tropical, e consequentemente, não teríamos um país com a importância agrícola que temos. AGRADECIMENTOS Ao Prof. Dr. Alberto Soares Corrêa pela sua orientação, por proporcionar esse projeto, por me ensinar e me guiar durante meu mestrado, por abrir as portas de seu laboratório e me motivar a fazer ciência. Agradeço por sua amizade, companheirismo e profissionalismo no ambiente de trabalho, e por ser um profissional que enxerga a saúde e o bem-estar de seus estudantes, Agradeço aos profissionais da Bayer, Renato Horikoshi e Patrick Dourado que providenciaram as coletas e auxiliaram na elaboração desse projeto, estendendo os valores da empresa para a sociedade. Agradeço aos funcionários da entomologia, em especial Luiz Maluta, que me auxiliou muito nos incontáveis documentos exigidos durante o mestrado,
