三种辉蝽的核型研究（半翅目：蝽科）

本首次研究了采于中国的辉蝽属三个种一辉蝽（Carbula obtusangula Reuter)、北方辉蝽（Carbula putoni(Jakovlev),凹肩辉蝽（Carbula sinica Hsiao et Cheng)的核型,结果表明,三个种均具有典型的蝽科核型即：2n(♂）＝14,具有XY性别决定机制,但是三个种的常染色体和性染色体在减数分裂时期的行为以及核型分析的结果和模式图各不相同,而且在北方辉蝽中出现了1－2条超数染色体,这些特点可为辉蝽属昆虫的形态分类及系统发育提供有用的证据。     

五种蝽科昆虫的细胞分类学研究（半翅目：异翅亚目）

研究了5种中国蝽科昆虫的核型和染色体的减数分裂行为,并采用核型分析软件对第一次减数分裂中期的染色体进行核型分析。结果表明：驼蝽Brachycerocoris camalus Costa、滴蝽Dybowskyia reticulata(Dallas）和红玉蝽Hoplistodera pulchra Yang3个种的染色体组成均为2n（♂）＝14,具有X－Y性别决定机制;减数分裂行为比较一致,但在中期－Ⅰ时,常染色体和性染色体的排列方式各不相同,可为蝽科昆虫的形态分类及系统发育提供有用的证据。二星蝽Eysarcoris guttiger(Thunberg）的染色体组成为2n（♂）＝15,具有X1X2Y性别决定机制,进一步证明了在半翅目昆虫的性染色体进化中碎片化过程起着很重要的作用;黑斑二星蝽Eysarcoris fabricii(Kirkaldy）的染色体组成为2n（♂）＝16,具有X－Y性别决定机制。后2种的核型结果,可为二星蝽属分类的进一步研究提供参考。

CYTOLOGICAL STUDIES OF PATERCULUS ELATUS (YANG) (HEMIPTERA:PENTATOMIDAE)

Abstract The karyotype of a Chinese pentatomid species Paterculus elatus (Yang) was studied in male germ cells prepared on air-dried slides stained with Giemsa. Karyotype analyses using specific software were made and model karyotype chart was presented. P. elatus (Yang ) has 16 chromosomes on mitosis metaphase plate and a X-Y sex chromosomal mechanism. The cytogenetic analysis has revealed the presence of a pair of m-chromosomes and a supernumerary chromosome.     

Effects of embryonic responses to clutch mates on egg hatching patterns of Pentatomidae (Heteroptera)

Stink bugs and shield bugs of the family Pentatomidae (Heteroptera) generally produce a clutch of densely deposited eggs. In a few species of this family, embryos hatch in response to some form of cues associated with the preceding hatching to synchronize egg hatching with clutch mates. The aim of the present study is to obtain a family‐wide understanding of the extent to which the hatching response to clutch mates accelerates hatching within egg clutches. Accordingly, the hatching patterns in intact egg clutches and eggs individually detached from egg clutches are compared in eight species among different genera. In Halyomorpha halys, hatching is significantly and highly synchronized by the effect of the hatching response: when eggs are not attached to each other, the hatching rate is only 3.8% at 15 min and exceeds 95% at 200 min. By contrast, when eggs are attached to each other, the hatching rate reaches more than 95% at 15 min. Hatching is also significantly synchronized by the hatching response in Nezara viridula (which shows relatively high hatching synchronization) and in Piezodorus hybneri and Plautia stali (both of which show milder hatching synchronization). Synchronization of hatching is not found to be promoted by a hatching response in Aelia fieberi, Dolycoris baccarum, Eurydema rugosum or Palomena angulosa. These findings reveal that the hatching response varies depending on the species in Pentatomidae, with a wide spectrum of effects on the hatching patterns of the egg clutches.     

Taxonomic review of the predatory stink bugs of the Korean Peninsula (Heteroptera: Pentatomidae: Asopinae), with a key to the Korean species and a discussion of their usefulness as biological control agents

Owing to their predatory feeding habits, many members of the stink bug subfamily Asopinae have been used as biological agents for controlling insect pests. Herein a taxonomical review of Korean Asopinae species is presented. The habitus and a detailed genital morphology of each species is illustrated together with the first key to the Asopinae species present in Korea. We report Eocanthecona kyushuensis (Esaki & Ishihara, 1950) for the first time on the Korean Peninsula and the subtropical species Andrallus spinidens has been confirmed in the southern part of Korea, but Troilus luridus has not been found in the Republic of Korea. All this information is of extreme importance for the correct identification and understanding of the biology and distribution of Asopinae species. We also present a discussion of the potential usefulness and viability of the stink bugs as biological control agents in Korea.

Reproductive ecology of predaceous Heteroptera

Reproductive ecology entails relating the physiology and behavior of an organism to its environment and the community in which it lives. Terrestrial predatory Heteroptera (including Anthocoridae, Geocoridae, Miridae, Nabidae, Pentatomidae, Phymatidae, and Reduviidae) display a wide range of reproductive ecologies. But in spite of this variability, a review of the literature reveals certain underlying trends that are useful in understanding how generalist predators function within their environments. First, the reproductive ecology of predatory bugs is inherently coupled to the physiology of the female and her eggs. Second, three population parameters are directly tied to reproduction (maturation rates, realized fecundity, and reproductive diapause) have great bearing on the rate of population increase and reproductive success of a predatory bug, but these three parameters fluctuate widely within and among species. The variables that affect these processes include the physiological status of the mother (mating status, age and size, and nutritional status), the abiotic environment in which she and her eggs live (temperature, photoperiod, water availability), and natural enemies that attack eggs and reproductive females. A final trend observed in the literature involves the hierarchy of events that must occur before a female finds a suitable oviposition site. Females all must locate preferred habitats, plants/substrates, and microsites in which to insert or deposit an egg, but they use a variety of tactics and cues in order to accomplish this, depending on their life history traits. Examining the factors that constrain and promote the reproductive potential of predatory Heteroptera will make biological control programs that center on them more reliable and sustainable.
