Isoenzymes for Four Coreid Species Identification (Hemiptera: Coreidae)

The vertical slab polyacrylamide gel electrophoretic technique is used to examine the esterase isozyme of four species (Hemiptera: Coreidae), the analysis has revealed that esterase zymogram can be divided into four zones. Esterase zymogram of intergeneric species show distinct difference, while some intrageneric common features are discovered. The clustering analysis shows that the taxonomic status of 4 species, and sex variance is bigger than individuals and is smaller than species.

Male Reproductive System and Spermatogenesis in Homoptera(Insecta:Hemiptera)

Morphology of the male reproductive system, chromosome behaviors during meiosis and spem tail structures in Homoptera and Heteroptera are compared in this paper. The sheathed testis is found in Fulgoroidea and Heteroptera, and unsheathed testis occurs in Cicadoidea, Cicadelloidea, Cercopoidea, Membracoidea, Psyloidea, Aphidoidea, Aleyrodoidea and Coccoidea. The testis also can be divide into three types by the shape of testicular follicles. The sphere-shaped type is found in Cicadoidea, Cicadelloidea, Cercopoidea, Membracoidea, Aphidoidea and Aleyrodoidea, the tube-shaped type observed in Fulgoroidea, Psyloidea and Coccoidea, and the lamella-shaped type represented by Heteroptera. It is suggested the unsheathed testis may be the primitive type in Homoptera. Meiosis can be divided into 6 type at least, i.e. 1） Cicadoid type; 2） Fulgoroid type; 3） Psyloid type; 4） Aphidoid type; 5） Aleyrodoid type; and 6） Coccoid type. At least four groups exhibit a diffuse stage during meiosis prophase l, they are Psyloidea, Fulgoroidea, Coccoidea and Heteroptera. Sperm tail structures are similar to those reported from other insects with a typical 9＋9＋2 axoneme except that in Aleyrodoidea and Coccoidea whose sperm tail is degenerated.

Studies on the Karyotype of Two Species in Orius Wolff (Hemiptera: Heteroptera: Anthocoridae)

The karyotype of two Chinese species in Orius were studied in male germ cells prepared on air dried slides stained with Giemsa. It is reported that two species have 24 chromosomes in diploid and X Y sex chromosomal mechanism. But the beha vior of chromosomes during meiosis between two species is different. Which show in the arrangment and location of the X chromosome and autosome at the late diakinesis as well as metaphase stage respectively and so on. These characteristics may be used in ta xonomy among species of Orius .

Studies on the Karyotype of Three Species in the Genus Orius Wolff (Hemiptera:Anthocoridae)

Karyotype of 3 species of the genus Orius Wolff were firstly studied using the Giemsa staining and squashing slides method in male germ cell. It is reported that number of chromosome and system of sex chromosome of haploid chromosome complement of these species is n=11A＋X （Y） in the first meiotic stage. However, the behavior of chromosomes among the species are different distinctly, thus cytotaxonomic character can be adopted to the identification among the three species.

Phylogeny of the subgenus Singhardina Mahmood (Hemiptera: Cicadellidae: Typhlocybinae: Typhlocybini) from China based on nuclear and mitochondrial gene sequences

Fragments of nuclear ribosomal 28S rDNA D2 divergent domain, mitochondrial 16S rDNA, and COI partial genes of 15 species in the subgenus Singhardina Mahmood from China were amplified and sequenced. Molecular phylogenetic trees were constructed using maximum parsimony, maximum likelihood and Bayesian inference methods. Results from these methods revealed similar topologies with recognizable relationships among subclades. The phylogenetic relationship of four species groups of subgenus Singhardina Mahmood from China is discussed for the first time. The results show that Singhardina Mahmood forms a single lineage representing a monophyletic group. The Eurhadina （Singhardina） rubra species group newly proposed in this study is likely the most basal species group within Singhardina Mahmood. The E. （Singhardina） robusta species group is the sister group of the E. （Singhardina） mamata species group. Molecular evidence supports including the E. （Singhardina） vittata species group in the E. （Singhardina） punjabensis species group.

A Cladistic Analysis on the Genera of Tinginae (Hemiptera:Heteroptera:Tingidae) from Northern China

In the present paper,the cladistics method is used to analyze the phylogenetic relationship of 16 genera of Tinginae (Hemiptera:Heteroptera:Tingidae) from northern China. 33 characters with 88 states were chosen based on the morphological comparison. The character matrix was formed through ingroup and outgroup analysis and computed using the computer programs MacClad (version 3 0 1), AutoDecay (version 3 0), PAUP (version 3 1 1) and Hennig 86 (version 1 5),and the same most parsimonious tree and Nelson consensus cladogram were obtained from both computation to explain the phylogenetic relationship among the genera (L=118,CI=0 454,RI=0 529). We categorized these genera involved in the analysis phylogenetically into 6 groups according to the results. They are Agramma group,Leptoypha group,Dictyla group,Catoplatus group,Physatocheila group and Derephysia group. The phylogenetic relationship among the involved genera is presented as (((((Derephysia group=( Lasiacantha ,( Acalypta ,( Galeatus ,( Dictyonota ,( Derephysia,Sphaerista ))))),Physatocheila group =(( Elasmotropis,Tingis ),(( Oncochila,Cochlochila ), Physatocheila ))),Catoplatus group= Catoplatus ),Dictyla group=( Monosteira,Dictyla )),Leptoypha group= Leptoypha ),Agramma group= Agramma ). These groups will not be regarded as higher classific taxa until more genera and data are available and further analysis are carried out.
