Abstract

Euschistus heros (Fabricius) (Hemiptera: Pentatomidae) is Brazil's most significant soybean stink bug pest, with outbreaks well-documented across various regions. However, during a collection expedition in soybean crops in Amapá State, Euschistus atrox (Westwood) was identified as the predominant Euschistus species in these areas. In this study, we characterized E. atrox both morphologically and molecularly, comparing it with E. heros. A laboratory experiment was designed to compare reproductive traits between the two species, and test for interspecific crosses. Female E. atrox exhibited lower fecundity compared to E. heros. The most surprising finding was that intercrosses between E. heros and E. atrox resulted in fertile offspring. We highlight the implications of these findings for species evolution and pest management in this critical group of insect pests.

巴西黄豆田中首次记录褐蝽（半翅目：五蝽科）：鉴定、繁殖性状及与大法氏褐蝽的杂交

Euschistus heros（半翅目：蝽科）是巴西最重要的大豆臭虫，在各个地区都有充分的暴发记录。然而，在对amapap州大豆作物的采集考察中，鉴定出该地区的优势种为Euschistus atrox （Westwood）。在本研究中，我们从形态和分子两个方面对其进行了表征，并将其与英雄e进行了比较。设计了一项室内实验，比较了两个物种之间的生殖性状，并测试了种间杂交。雌鼠的繁殖力低于雄鼠。最令人惊讶的发现是，雄蜂和雄蜂的杂交产生了可育的后代。我们强调了这些发现对这一重要害虫群体的物种进化和害虫管理的影响。
