A mutation affecting eye color was discovered in (Rambur) (Hemiptera: Miridae). This species is an important biological control agent used to manage whiteflies and other arthropod pests in greenhouse crops. Typically, these predators exhibit a dark eye coloration, ranging from garnet to black. However, individuals with bright red eyes have been identified within wild populations, making them easily distinguishable. The objective of this study was to study the mode of inheritance of the red eye color mutation observed. Additionally, a comparative analysis of key biological traits was conducted between individuals carrying the mutation and those from a wild-type population. From these specimens, a population carrying this eye color mutation, referred to as , was established. Genetic analyses revealed that the red coloration is controlled by a single recessive allele located on an autosomal chromosome. Red-eyed individuals exhibited superior performance in biological traits, including greater body size in both males and females, as well as increased fecundity and longevity in females. The utilization of this red-eyed variant could be valuable as a visual marker in ecological and biological studies of population dynamics.
在（兰布尔）（半翅目：盲蝽科）中发现了一种影响眼睛颜色的突变。该物种是一种重要的生物防治剂，用于控制温室作物中的粉虱和其他节肢动物害虫。通常，这些捕食者的眼睛颜色较深，从石榴红到黑色不等。然而，在野生种群中发现了眼睛为鲜红色的个体，这使得它们很容易被区分出来。本研究的目的是研究观察到的红眼颜色突变的遗传模式。此外，还对携带该突变的个体与野生型种群个体的关键生物学特性进行了比较分析。从这些标本中，建立了一个携带这种眼睛颜色突变的种群，称为 。遗传分析表明，红色由位于常染色体上的单个隐性等位基因控制。红眼个体在生物学特性方面表现出优势，包括雄性和雌性体型更大，以及雌性的繁殖力和寿命增加。这种红眼变体在种群动态的生态和生物学研究中作为视觉标记可能具有重要价值。
