Abstract
The primary culture of insect cells often suffers from problems with poor reproducibility in the quality of the final cell preparations. The cellular composition of the explants (cell number and cell types), surgical methods (surgical duration and surgical isolation), and physiological and genetic differences between donors may be critical factors affecting the reproducibility of culture. However, little is known about where biological variation (interindividual differences between donors) ends and technical variation (variance in replication of culture conditions) begins. In this study, we cultured larval fat bodies from the Japanese rhinoceros beetle, Allomyrina dichotoma, and evaluated, using linear mixed models, the effect of interindividual variation between donors on the reproducibility of the culture. We also performed transcriptome analysis of the hemocyte-like cells mainly seen in the cultures using RNA sequencing and ultrastructural analyses of hemocytes using a transmission electron microscope, revealing that the cultured cells have many characteristics of insect hemocytes.

Abstract
The first continuous cell line from the neonate larval tissues of Blaps rhynchoptera, which has been used as a folk medicine in Yunnan Province, China, was established and designated RIRI-BR1. This cell line was serially subcultured in Schneider's medium supplemented with 15% fetal bovine serum (FBS). The cells grew adherent to culture flasks and exhibited spindle-like and polygonal shapes. The growth rate was determined at the 50th passage, and the population doubling time was calculated to be 79.5 h. The post-thaw viability of the cell line at different passages showed that the cells from higher passages could be recovered easier after cryopreservation than the cells from lower passages. The average chromosome numbers from cells of the RIRI-BR1 cell line at passages 5 to 50 ranged from 12 to 130. The rDNA internal transcribed spacer (ITS) sequence analysis indicated that the RIRI-BR1 cell line was derived from B. rhynchoptera.

A cell line derived from the red flour beetle Tribolium castaneum (Coleoptera: Tenebrionidae). In Vitro Cell Dev Biol Anim 2012; 48:426-33.

Abstract
The red flour beetle, Tribolium castaneum, is a model organism for agricultural and medical research and its complete genome is sequenced. We established a continuously replicating T. castaneum cell line to complement existing physiological, genetic, and genomic research tools. We set up trial cell cultures from egg, pupa, and adult stages as tissue sources and incubated them in six separate cell culture media to determine the optimal combination of tissue source and medium for cell replication. Our most promising culture was generated by co-culturing adult (∼75 %) and pupal tissues in EX-CELL 420 medium containing 9 % FBS. Our new cell culture is designated BCIRL-TcA-CLG1 (TcA) and it has been subcultured more than 90 times. Amplification of genomic DNA with species-specific primers yielded DNA fragments of the expected sizes and with sequences identical to those from the published Tribolium genome. Additionally, we characterized this line using DNA fingerprinting (DAF-PCR) and compared it with three other coleopteran cell lines and its conspecific pupae to confirm identity. Its doubling time is 155.2 hr. Early passages consisted of attached cells and vesicles in suspension, whereas later passages consisted primarily of attached, spherical cells. Similar to other established cell lines, the ploidy of TcA cells was variable, ranging from 20 chromosomes/cell (diploid) to above 30 chromosomes/cell. TcA cells withstood incubation at 40°C for 1 h with no decrease in viability. We recorded increased levels of one heat shock protein (43 kDa) and of the hsp68a transcript following exposure to 40°C. Taken together, this represents the first report of a continuously replicating T. castaneum cell line. We expect the BCIRL-TcA-CLG1 line will become a useful tool in Tribolium research.

Abstract
The insecticidal and phytotoxic activities of destruxins (dtxs) have been well studied. The cyclodepsipeptides, which are dtxs mainly isolated from the fungus Metarhizium anisopliae and other fungi, have been well characterized in vitro and in vivo. A succession of important function, such as antitumoral, antiviral, insecticidal, cytotoxic, immunosuppressant, phytotoxic, and antiproliferative effects have been observed. To date, 39 dtxs derivatives have been identified. Dtxs possess a variety of biological activities, including acting as virulence factors for specific insects, a V-ATPase inhibitor that provides a basis for the development of new drug to against osteoporosis, cancer, or biological control agents, etc. Here, we focus on some of the research progress made on understanding dtxs during the last decade, introduce some of the newly identified dtx members, especially from M. anisopliae, and give an overview of the applications of dtxs. Using the dtxs to learn about and moderate biological events has advanced significantly during the past year. We believe that several ongoing dtx application fields may benefit from the reviewed information herein.

Abstract
We have established a continuous cell line from the fat body tissue of the longicorn beetle Plagionotus christophi. The cells have been serially subcultured in MGM450 medium, and the line has been designated as PC-1. The cells were grown in suspension and comprise largely flattened spindle- or oval-shaped cells morphologically related to blood cells of longicorn beetles. The chromosome number ranged from 19 to 36, with a mode of 20 (diploid). The growth curve was determined at the 100th passage, and the population doubling time was calculated to be 3.79 d. Isozyme analysis of malic enzyme, phosphoglucose isomerase, and phosphoglucomutase revealed that PC-1 cells were enzymatically distinct from coleopteran XP-1, AnCu-35, dipteran AeAl-2, and lepidopteran GaMe-LF1 cell lines.

Abstract
The corn borer, Ostrinia nubilalis, is a very important pest in different countries, and the in vitro system of the insect could be a useful tool for isolation and characterization of the pathogens and physiological responses of the insect. In this context, a cell line was derived from the hemocytes of the European corn borer and was named AFKM-On-H for, respectively, O. nubilalis, Armand Frappier, King Mongkut Institutes, and Hemocytes. This cell line was initiated and maintained in Ex-Cell 400 medium supplemented with 10% heat-inactivated fetal bovine serum. The cells, mostly spherical in shape, not firmly attached to the plastic culture flasks, were passaged up to 200 times by repeated gentle pipetting of the cells. The doubling times at the 80th and 125th passages at 28 degrees C and at the 122th and 169th passages at 25 degrees C were 40, 29, 35, and 34 h, respectively. The AFKM-On-H cell line was further characterized by the morphology, karyotype, random amplified polymorphic DNA analysis, and isozyme profiles. Susceptibility of the cell line to cytoplasmic polyhedrosis viruses (CPV) Euxoa scandens (EsCPV), Dendrolimus punctatus (DpCPV), and Choristoneura fumiferana (CfCPV); nuclear polyhedrosis viruses [Autographa californica (AcMNPV) wild type and recombinant, Antherea yammamai (AnyaNPV)]; and Chilo iridescent virus was demonstrated. Relative sensitivities of the cell line to Bacillus thuringiensis and Metarhizium anisopliae toxins and effects of the molting hormone 20-hydroxyecdysone on this new hemocyte cell line were characterized.

Abstract
Random amplified polymorphic DNA (RAPD) analysis was used to characterize 11 insect cell lines, including six from lepidoptera (five species), one from diptera and four from coleoptera (one species: Leptinotarsa decemlineata). Whatever the order and even when comparing two closely related species from the same genus (Spodoptera), the DNA fingerprints are very different from one species or from one primer to the other. On the other hand, two independently isolated cell lines from the lepidopteran Phthorimaea operculella produce nearly identical profiles with only minor differences. Finally, a statistical analysis based on Nei's similarity coefficient was performed on the fingerprints of four independent cell lines from the Colorado potato beetle, L. decemlineata. Each possesses a common recognizable pattern also found in field-collected insects, while also showing a series of polymorphic markers which allow one to distinguish each cell line from the three others. RAPD fingerprinting, together with the use of appropriate statistics, thus constitutes a highly specific method both for the authentication of the species from which a cell line was developed and for the individual characterization of each cell line from a given species.
