Revision of the lygaeid genus Nysius (Heteroptera: Lygaeidae: Orsillinae) of Japan, with description of a new species

Abstract

Japanese species of the lygaeid–orsilline genus Nysius were revised, and five species including a new species, N. hidakai, were recognized. Male and female genitalia of all the species were illustrated, and a key to species of Japanese Nysius was provided. The DNA barcoding information of each species except N. expressus were recorded.

Oviposition and development response of perilla seed bugs (Nysius sp.) (Heteroptera: Lygaeidae) to five crop seeds

“…from a field of perilla at the Department of Southern Area Crop Science (DSACS), National Institute of Crop Science (NICS), Rural Development Administration (RDA; http://www.nics.go.kr/english/index.do), Miryang, Korea, in 2018. Adult bugs were separated to species ( N. plebeius and N. hidakai ) using morphological keys ( N. plebeius —smaller, body size [3.3–4.4 mm], membrane usually with dark marking; N. hidakai —larger, body size [4.1–4.9 mm], membrane usually without brown marking, if present, small and obscure; Nakatani, 2015) and molecular sequencing (Folmer, Black, Hoeh, Lutz, & Vrijenhoek, 1994). The offspring of these field‐collected bugs were maintained as separately colonies in the laboratory on perilla seeds.…”

“…used in our study were collected with a sweep net (40 cm dia.) from a field of perilla at the Department 4.1-4.9 mm], membrane usually without brown marking, if present, small and obscure; Nakatani, 2015) and molecular sequencing (Folmer, Black, Hoeh, Lutz, & Vrijenhoek, 1994). The offspring of these field-collected bugs were maintained as separately colonies in the laboratory on perilla seeds.…”

“…Despite the potential threat of Nysius species to several crops, studies on occurrence, distribution and hosts preference of Nysius species are rare in Korea (Kim et al., 1994; Nakatani, 2015). Nakatani (2015) has reported three Nysius species ( N. expressus , N. plebeius and N. hidakai ) from Korea, and we recently reported that N. inconspicuus is also present in Korea (R Maharjan, unpublished). Kim et al.…”

“…Nysius species, such as N. expressus Distant, N. plebeius Distant, N. hidakai Nakatani and N. inconspicuus Distant, are some of the pests of the perilla plant in Korea (Kim, Kim, Kang, Shin, & Lee, 1994; Nakatani, 2015; R Maharjan, unpublished). Among the species, the most dominant species were N. plebeius and N. hidakai in Korea (Kim et al., 1994, R Maharjan, unpublished).…”

First Record, Prevalent Hosts, Biological and Managing Attributes of False Chinch Bug (Hemiptera: Lygaeidae) Injuring Helianthus annuus, Brassica and Chenopodium from Punjab, Pakistan

“…On legs, tarsus has 3 conspicuous segmentation with a cushioning pad on the lower terminal side of each claw and anterior enlarged femur. Forewings membranes are conspicuous with 3-5 microscopic veins with multivariate colors, shape and sizes ( Figures 1 and 2) [16]. The specimens were identified from presented characters [12].…”
