    ABSTRACT: The parasitoid Hymenoptera are one of the most important groups of natural enemies of agriculture and forestry pests and have been used as biological control agents in IPM programs for a long time. The systematic research on parasitoids and their associations with hosts lays a solid base for biological control of pests. Here we summarize the taxonomic studies undertaken on the parasitoid wasps in China in the last eight decades. At present about 48 families in 12 superfamilies of parasitoid Hymenoptera are known in China, of which the majority of the families have been studied to some extent while a number of them are still poorly studied. Around 6000 species of 32 families which dealt with in this paper are known in China, and some of them have been successfully and widely used in the existing biological control while others are potentially useful in future biocontrol program. This overview provides the international audience a general idea about the current state of the systematic study of parasitoid Hymenoptera conducted in China, the known species of parasitoids and the native and introduced species used in biocontrol in China.

    ABSTRACT: The Chinese fauna of the family Trigonalyidae Cresson, 1887, is revised, keyed and fully illustrated for the first time. Eight genera of this family (Bakeronymus Rohwer, 1922, Bareogonalos Schulz, 1907, Jezonogonalos Tsuneki, 1991, re-instated, Lycogaster Shuckard, 1841, Orthogonalys Schulz, 1905, Pseudogonalos Schulz, 1906, Taeniogonalos Schulz, 1906 and Teranishia Tsuneki, 1991) are recorded from China. The genus Ischnogonalos Schulz, 1907, is synonymized with Taeniogonalos Schulz, 1906. In total 40 valid species are recognized.

    ABSTRACT: Two endoparasitoids, Cotesia vestalis and Oomyzus sokolowskii, parasitize the same host, larvae of Plutella xylostella. These two species have evolved different parasitization strategies. O. sokolowskii expresses a single factor, venom, and exerts virtually no detrimental effects on the development of its host. C. vestalis, on the other hand, injects polydnavirus (PDV) and venom during oviposition, and teratocytes are released into the host's hemolymph after egg hatching. Parasitization suppresses host immune reactions and redirects its developmental program. Because both these species parasitize the same stage of their hosts, there is the possibility of multiparasitism in nature. Only one species survives multiparasitism and because of its parasitic strategy, we hypothesized that C. vestalis would invariably be the stronger competitor. We designed competition experiments which revealed that C. vestalis is a stronger competitor than O. sokolowskii. We also show that C. vestalis survives intrinsic competition with O. sokolowskii through two mechanisms: physical attack and physiological suppression. We discovered melanized wounds on O. sokolowskii eggs and larvae, which is strong evidence of physical attacks. The physiological suppression is due to PDV and venom injected by C. vestalis. To test this idea more rigorously, we designed a pseudoparasitization experiment which revealed that no O. sokolowskii emerged from multiparasitized hosts when infertile C. vestlais eggs and normal O. sokolowskii larvae are both present inside the same host. These results support our hypothesis that C. vestalis is the stronger competitor and demonstrate two mechanisms that account for the outcome of intrinsic competition between these two endoparasitoids.

    ABSTRACT: Strand asymmetry in nucleotide composition is a remarkable feature of animal mitochondrial genomes. Understanding the mutation processes that shape strand asymmetry is essential for comprehensive knowledge of genome evolution, demographical population history and accurate phylogenetic inference. Previous studies found that the relative contributions of different substitution types to strand asymmetry are associated with replication alone or both replication and transcription. However, the relative contributions of replication and transcription to strand asymmetry remain unclear. Here we conducted a broad survey of strand asymmetry across 120 insect mitochondrial genomes, with special reference to the correlation between the signs of skew values and replication orientation/gene direction. The results show that the sign of GC skew on entire mitochondrial genomes is reversed in all species of three distantly related families of insects, Philopteridae (Phthiraptera), Aleyrodidae (Hemiptera) and Braconidae (Hymenoptera); the replication-related elements in the A+T-rich regions of these species are inverted, confirming that reversal of strand asymmetry (GC skew) was caused by inversion of replication origin; and finally, the sign of GC skew value is associated with replication orientation but not with gene direction, while that of AT skew value varies with gene direction, replication and codon positions used in analyses. These findings show that deaminations during replication and other mutations contribute more than selection on amino acid sequences to strand compositions of G and C, and that the replication process has a stronger affect on A and T content than does transcription. Our results may contribute to genome-wide studies of replication and transcription mechanisms.

    ABSTRACT: Few complete mitochondrial genomes representing limited families in the order Hymenoptera have been sequenced. Here, we sequenced the complete mitochondrial genome of Diadegma semiclausum (Hymenoptera: Ichneumonidae). This genome is 18 728 bp long, the second largest hexapod mitochondrial genome sequenced in its entirety and that with the highest A+T content at 87.4%. Four tRNAs are rearranged compared with the ancestral arrangement. Gene rearrangement mechanisms are different among all three rearranged regions. Six tRNAs have a large variable loop, which is not found in other metazoan mitochondrial genomes. trnS(AGY) uses the abnormal anticodon TCT but trnK uses the normal CTT. The A+T-rich region is very long (2161 bp). An extremely A+T-rich (99.1%) 1515 bp tandem repeat region with three types of repeat elements is located between cox1 and cox2, and the most likely ancestral element originated from the 3' end of cox1. Independent tandem duplications followed by mutation-insertion-deletion is the best model to explain the formation of this region. These results indicate that independent evolutionary events occurred extensively, such as gene rearrangement events, gene rearrangement mechanisms, derivation of tRNA variable loops, and tandem repeat region evolutionary processes, all of which likely contribute to the diversified features of hymenopteran mitochondrial genomes.

    ABSTRACT: Diadegma semiclausum (Hellén) (Hymenoptera: Ichneumonidae) is one of the most important biological control agents of the diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae). Each immature stage of D. semiclausum was studied by dissecting parasitized hosts in the laboratory at 22 ± 1°C and 70-75% RH. Results show that the egg is hymenopteriform, lacking appendages. The larvae seem to be hypermetamorphic, with four instars. The pupal period has two distinct phases: 1) phase I, larval-like with remarkable groups of urate cells; and 2) phase II, exarate pupal appearance with a pigmentation sequence of eyes, ocelli, mandibles, thorax, abdomen, and antennae. All stages and sequences are illustrated with detailed photomicrographs.
