Abstract
We have developed an online database describing the known cell lines from Coleoptera, Diptera, Hemiptera, Hymenoptera, and Lepidoptera that were developed from agricultural pests. Cell line information has been primarily obtained from previous compilations of insect cell lines. We conducted in-depth Internet literature searches and drew on Internet sources such as the Cellosaurus database (https://web.expasy.org/cellosaurus/), and inventories from cell line depositories. Here, we report on a new database of insect cell lines, which covers 719 cell lines from 86 species. We have not included cell lines developed from Drosophila because they are already known from published databases, such as https://dgrc.bio.indiana.edu/cells/Catalog. We provide the designation, tissue and species of origin, cell line developer, unique characteristics, its use in various applications, publications, and patents, and, when known, insect virus susceptibility. This information has been assembled and organized into a searchable database available at the link https://entomology.ca.uky.edu/aginsectcellsdatabase which will be updated on an ongoing basis.

Developing an Ephestia kuehniella Hemocyte Cell Line to Assess the Bio-Insecticidal Potential of Microencapsulated Helicoverpa armigera Nucleopolyhedrovirus Against Cotton Bollworm (Lepidoptera: Noctuidae) Larva. JOURNAL OF ECONOMIC ENTOMOLOGY 2020; 113:2086-2095.

Abstract
Helicoverpa armigera Nucleopolyhedrovirus (HearNPV) (genus: Alphabaculovirus, incertae sedis: Baculoviridae) has been used to control Helicoverpa armigera (Hübner). A reproducible and susceptible cell line was prepared from the hemocytes of Ephestia kuehniella in Grace and Ex-Cell 420 media. The population doubling time of these cloned cell cultures during the logarithmic phase were about 2.3 and 3.7 d for Ex-Cell 420 and Grace's media, respectively. When 60% confluence occurred, cells were infected by viral inoculums. All biochemical compounds were significantly changed relevant to cellular metabolism due to HearNPV infection. In order to improve its stability, two polymer formulations were used, i.e., formulation A (sodium alginate, gelatin, starch, and molasses) and formulation B (cottonseed kernel extract, Bran, glycerol, boric acid, egg white, and sugar). Formulant A provided high photostability by exhibiting 83.2 ± 3% efficacy and 88.66 ± 2.1% original activities remaining after 72 h UV exposure. Percentage original activity remaining of unformulated HearNPV and formulated mixture of B was 38.66 ± 2.6% and 9.33 ± 1.3%, respectively, after 72 h UV-irradiation. The virulence of the HearNPV proliferated from the Ex-Cell medium was similar to the virulence of wild-type HearNPV with LC50 of 7.7×105 OBs/ml. Formulant A, revealed only 20.0 ± 1% reduction in efficacy while the unformulated virus and formulant B faced a reduction of 90.0 ± 3% and 64.0 ± 2% after 72 h of UVA irradiation. Formulant A thus showed a high potential to protect HearNPVs microparticles against UV-inactivation suggesting a new platform for more efficient biological-management of cotton bollworm (specific name Helicoverpa armigera, genus: Helicoverpa, Lepidoptera: Noctuidae) in vivo.

Establishment and characterization of novel cell lines derived from six lepidopteran insects collected in the field. In Vitro Cell Dev Biol Anim 2020; 56:425-429. [PMID: 32246241 DOI: 10.1007/s11626-020-00438-5] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2019] [Accepted: 02/24/2020] [Indexed: 10/24/2022]
Abstract
Insect cell lines are used to study cellular interactions and gene functions in vitro in several research areas. However, suitable cell lines for experiments are not always available, especially in non-model species. Here, we established novel cell lines derived from fat bodies of six lepidopteran insects: Cydia kurokoi (named NARO-Cyku), Cephonodes hylas (NARO-Cehy), Haritalodes basipunctalis (NARO-Haba), Theretra oldenlandiae (NARO-Thol), Lymantria dispar (NARO-Lydi), and Hyphantria cunea (NARO-Hycu) collected in the field. The larval fat body was a promising tissue for the starting material when samples were limited due to field collection. It was critical that the medium volume was kept to a minimum for primary culture to maintain adherence of the fat body cells to the flask. The flask was coated with poly-L-lysine for effective induction of adherence and cell division. The identities of cell lines were confirmed using DNA barcoding with the mitochondrial cytochrome c oxidase I gene after cultures were passaged over 50 times. All lines except for NARO-Lydi and NARO-Hycu are adherent cells, and population doubling time of six cell lines ranged from 1.03 to 2.49. Induction of gene expression was practicable in the four adherent cell lines as revealed by transfection of expression vectors and found the immediate early 2 and the Bombyx actin 3 were effective gene promoters. The results suggest that these cell lines are capable of gene functional analysis. Thus, establishments of cell line using our methods for non-model lepidopterans could make a practical contribution to pest management and insect utilization.

Functional Characterization of the Group I Alphabaculovirus Specific Gene ac73. Virol Sin 2019; 34:701-711.

Abstract
Baculoviridae is a family of large DNA viruses that specifically infect insects. It contains four genera, Alpha-, Beta-, Gamma-, and Deltabaculovirus. Alphabaculovirus is further divided into Group I and II, and Group I appears to be emerged most recently among all baculoviruses. Interestingly, there are 12 Group I specific genes that are only found in this lineage. Studying these genes is helpful to understand how baculoviruses evolved. Here, we reported the functional analyzing results of ac73, a function unknown Group I specific gene of Autographa californica multiple nucleopolyhedrovirus (AcMNPV) which is the type species of baculovirus. The AC73 protein encoded by ac73 was found to be expressed during the late stage of infection and incorporated into the nucleocapsids of budded virus (BV) and occlusion-derived virus (ODV). In infected cells, AC73 resided mainly in the ring zone region of the nucleus, and appeared to be assembled into occlusion bodies (OBs). The ac73 knockout and repaired viruses were constructed and studied by in vitro and in vivo infection. Although ac73 was not essential for BV and ODV or OB formation, the BV titer and viral infectivity in insect larvae of ac73 knockout AcMNPV decreased by about 5-8 and 3-4 fold compared to those of wild type virus, respectively, suggesting ac73 contributed to infectious BV production and viral infectivity in vivo. This research provides new insight into the function of this Group I specific gene.

A Role for the Anti-Viral Host Defense Mechanism in the Phylogenetic Divergence in Baculovirus Evolution. PLoS One 2016; 11:e0156394.

Abstract
Although phylogenic analysis often suggests co-evolutionary relationships between viruses and host organisms, few examples have been reported at the microevolutionary level. Here, we show a possible example in which a species-specific anti-viral response may drive phylogenic divergence in insect virus evolution. Two baculoviruses, Autographa californica multiple nucleopolyhedrovirus (AcMNPV) and Bombyx mori nucleopolyhedrovirus (BmNPV), have a high degree of DNA sequence similarity, but exhibit non-overlapping host specificity. In our study of their host-range determination, we found that BmNPV replication in B. mori cells was prevented by AcMNPV-P143 (AcP143), but not BmNPV-P143 (BmP143) or a hybrid P143 protein from a host-range expanded phenotype. This suggests that AcMNPV resistance in B. mori cells depends on AcP143 recognition and that BmNPV uses BmP143 to escapes this recognition. Based on these data, we propose an insect-baculovirus co-evolution scenario in which an ancestor of silkworms exploited an AcMNPV-resistant mechanism; AcMNPV counteracted this resistance via P143 mutations, resulting in the birth of BmNPV.

Identification of amino acid residues of AcMNPV P143 protein involved in rRNA degradation and restricted viral replication in BM-N cells from the silkworm Bombyx mori. Virology 2015; 485:244-51. [PMID: 26313611 DOI: 10.1016/j.virol.2015.08.008] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2015] [Revised: 07/30/2015] [Accepted: 08/08/2015] [Indexed: 11/22/2022]
Abstract
We previously demonstrated that rRNA undergoes rapid and extensive degradation in Bombyx mori BM-N cells upon infection with AcMNPV, which is triggered by AcMNPV P143 (Ac-P143) protein. Here, we showed that six amino acid residues of Ac-P143 protein, distributing between positions 514 and 599, are involved in rRNA degradation in BM-N cells. The six residues are highly conserved among P143 proteins from AcMNPV, HycuMNPV, SeMNPV and SpltMNPV, which trigger rRNA degradation in BM-N cells upon infection, but are only partially conserved in Bm-P143 protein, which does not induce rRNA degradation in BM-N cells. We also demonstrated that substitution of only two selected residues (N565S/L578F) of Bm-P143 protein with the corresponding Ac-P143 protein residues generates a mutant Bm-P143 protein that is capable of triggering rRNA degradation in BM-N cells. These results indicate that BmNPV evolved a unique P143 protein to evade the antiviral response and allow replication in B. mori cells.

Abstract
Sarconesiopsis magellanica (Le Guillou) (Diptera: Calliphoridae) is a necrophagous fly that is important in both human and veterinary medicines. This insect has been registered in Colombia as a biological indicator in estimating post-mortem interval. Insect cell cultures are an important biotechnological tool for basic and applied studies, and cell cultures derived from S. magellanica embryonic tissues are described in this study. S. magellanica embryonated eggs were taken for tissue explants. These were seeded in L-15, Grace/L-15, Eagle MEM, MM, VP12, MM/VP12, and Schneider culture media. The morphological, cytogenetic, biochemical, and molecular characteristics of the cell cultures were examined. Cell growth was achieved in the L15, Grace/L15, and Schneider culture media, and the confluent monolayers were obtained 8, 10, and 19 days after the embryonated eggs were explanted. However, the Schneider medium was the most efficient to develop the subcultures, and 21 passages have been maintained. The cell morphology of the primary cell cultures was initially heterogeneous, but in the confluent monolayer and in the subcultures there was greater cell morphology uniformity, fibroblastoid types being predominant. Cultured cells had a chromosomal number of 12, and the karyotypic complement consisted of five pairs of somatic chromosomes and one sexual pair. The cell culture isozyme patterns of S. magellanica coincided with adult samples from the same species. The molecular analysis, using RAPD-PCR, demonstrated the authentication of the cell cultures of this fly and their differentiation from other cultures derived from two sand flies species. This cell line is a new in vitro model that will be used in biomedical and biotechnological studies.

Abstract
The first continuous cell line from the embryo of Gampsocleis gratiosa (Orthoptera: Tettigoniidae), designated as RIRI-GG1, was established. This cell line was serially subcultured in modified Grace medium. The cells were grown adherent to a culture flask and had spindle-like and polygonal shapes. The chromosome number ranged from 26 to 79 at the 50th passage, and 68% of cells had a diploid chromosome number. The growth rate was determined at the 53rd passage, and the population doubling time was calculated to be 122.1 h. The rDNA internal transcribed spacer and the mitochondrial cytochrome c oxidase subunit I gene sequence analysis indicated that the RIRI-GG1 cell line was derived from G. gratiosa. This cell line had no apparent susceptibility to Autographa californica nucleopolyhedrovirus and Bombyx mori nucleopolyhedrovirus.
