“…However, in Haematobia irritans (Lohmeyer et al ., ), Exorista japonica (Ichiki et al ., ) and Lygus lineolaris (Snodgrass, ), natality and egg eclosion are not significantly different between mutant and wild types. In our study, there were no significant differences between the red‐eye mutant and brown‐eye wild types in terms of the number of eggs produced per females, percentage of egg validity and third to fifth instar survival, which is different from the red‐eye mutant in Japan (Mochida, ) but is the same with the orange‐eye mutant in Korea (Seo et al ., ). However, the first to third instar nymph survival rate was lower in red‐eye mutants than in the brown‐eye ones, and this may be the reason why the ratios of brown‐eye to red‐eye BPH were biased in several crosses.…”

“…Compound eye color is an important biological character of insects and many eye color mutants have been described in Diptera (Lohmeyer et al ., ), Hemiptera (Mochida, ; Shimizu & Kawasaki, ; Snodgrass, ; Seo et al ., ), Coleoptera (Lorenzen et al ., ) and Lepidoptera (Wraight et al ., ). The mutated eye colors include red, white, yellow and so on.…”

A red-eye colony was established in our laboratory in brown planthopper (BPH), Nilaparvata lugens (Stål), a major rice pest in Asia. Except for the red-eye phenotype, no other differences were observed between the wild-type (brown eye) and the mutant-type (red eye) in external characters. Genetic analysis revealed that the red-eye phenotype was controlled by a single autosomal recessive allele. Biological studies found that egg production and egg viability in the red-eye mutant colony were not significantly different from those in the wild-type BPH. Biochemical analysis and electronic microscopy examination revealed that the red-eye mutants contained decreased levels of both xanthommatin (brown) and pteridine (red) and reduced number of pigment granules. Thus, the changes of amount and ratio of the two pigments is the biochemical basis of this red-eye mutation. Our results indicate that the red-eye mutant gene (red) might be involved in one common gene locus shared by the two pigments in pigment transportation, pigment granule formation or some other processes.

“…The brown planthopper (BPH), N. lugens, is a hemimetabolism insect and a notorious rice pest in East Asian countries (Cheng, 2009). The wild-type compound eye color of BPH is brown, while red-eye color mutation phenotype can also be observed (Seo et al, 2011;Liu et al, 2014). In order to clarify the ommochrome synthesis pathway of this insect pest, we cloned and characterized the cardinal ortholog gene from BPH.…”

karmoisin and cardinal ortholog genes participate in the ommochrome synthesis of Nilaparvata lugens (Hemiptera: Delphacidae)

Ommochrome is the major source for eye coloration of all insect species so far examined. Phenoxazinone synthetase (PHS) has always been regarded as the terminal step enzyme for ommochrome formation, which is encoded by cardinal or karmoisin genes. Our previous study indicated that the karmoisin ortholog gene (Nl-karmoisin) product in the brown planthopper (BPH) was a monocarboxylate transporter, while not a PHS. Here, based on full-length complementary DNA, the cardinal ortholog gene in BPH (Nl-cardinal) product was predicted to be a haem peroxidase rather than a PHS. We suggest for the first time that neither karmoisin nor cardinal encodes the PHS, but whether PHS participates in BPH eye pigmentation needs further research. Nymphal RNA interference (RNAi) experiments showed that knockdown Nl-cardinal transcript led the BPH ocelli and compound eye to color change from brown to red, while knockdown Nl-karmoisin only made the ocelli present the red phenotype. Notably, not only the Nl-cardinal transcript, dscd injection (Nl-cardinal targeting double-stranded DNA (dsRNA)) also significantly reduced the Nl-karmoisin transcript by 33.7%, while dska (Nl-karmoisin targeting dsRNA) injection did not significantly change the Nl-cardinal transcript. Considering the above RNAi and quantitative real-time polymerase chain reaction results, we propose that Nl-cardinal plays a more important role in ommochrome synthesis than Nl-karmoisin, and it may be an upstream gene of Nl-karmoisin. The present study suggested that both karmoisin and cardinal ortholog genes play a role in ommochrome synthesis in a hemimetabolous insect.

“…The mating behavior, egg production, developmental duration and mortality of nymphal stages were not significantly different between the normal-eyed and colored-eye mutant colonies [2] [3]. However, some phenotypes (i.e., egg lethal effect, poor fecundity and survival ability) might be related to the eye color mutations [3] [5]. Genes having a stronger compensation ability for reproduction may also closely link to the red eye allele [6].…”

“…The BPH has a diploid chromosome number of 30 (28 autosomes combined with the sex determination system XY and XX in males and females, respectively) [1]. Among the few visible mutations in the BPH, eye color is one of the mutations that are regularly observed in laboratories [2] [3]. In Delphacidae, red-eyed mutants were reported in the small brown planthopper Laodelphax striatellus (Fallén) [4] and BPH [5].…”

Chromosomal Location of a Recessive Red-Eye Mutant Gene in the Brown Planthopper <i>Nilaparvata lugens</i> (Stål) (Insecta: Hemiptera)

The color of compound eyes is an important biological characteristic of insects. A red eye color mutation is commonly found in the brown planthopper (BPH), Nilaparvata lugens (Stål) (Hemiptera: Delphacidae), a serious insect pest of rice in tropical and temperate Asia. The genetic inheritance and physiological effect of the eye color mutation in the BPH have been studied, but the location of a red gene controlling the red eye mutant phenotype on a chromosome has not been elucidated. In this study, simple sequence repeats (SSRs), together with bulked segregant analysis (BSA), was performed to identify and map the location of the red gene. A total of 387 SSR markers distributed throughout the BPH autosome were used to survey two bulked DNA samples. Samples were generated from 29 brown-eyed and 29 red-eyed individuals derived from an F 2 generation of a cross between brown-eyed wild type and red-eyed mutant colonies. The SSR marker BM20 was shown to be associated with the red eye mutant phenotype. Ninety-five offspring of the F 2 generation were then used to map the gene. The present study constitutes the discovery of the location of the red gene, which may lead to the acquisition of the genetic determinant of the compound eye color mutation in BPH.
