Abstract Background Biological pesticides, especially baculovirus, often lose their activity under the influence of external light, temperature, and other changes. This limited application them. The present study was aimed to prolong biological ensure efficacy a pesticide using microencapsulation technology. Results In this study, gelatin/carboxymethylcellulose (CMC)- Spodoptera litura nucleopo...

To salvage marine ecosystems from fishery overexploitation, sustainable and efficient aquaculture must be emphasized. The knowledge obtained available genome sequence of organisms has accelerated in many cases. black tiger shrimp (Penaeus monodon) is one the most prominent cultured penaeid shrimps (Crustacean) with an average annual global production half a million tons last decade. However, it...

conclusions: the recombinant baculovirus constructed in this work has proper characteristics to produce h5n1 influenza virus-like particles in sf9 cells. results: restriction map of pfastbacihnm1 plasmid confirmed the fidelity of the clone. the pcr carried out on the recombinant bacmids as template indicated that a proper homologous recombination has occurred between pfastbacihnm1 donor plasmid...

BACKGROUND White spot disease (WSD), a major threat to sustainable aquaculture worldwide, is caused by White spot syndrome virus (WSSV). The diagnosis of WSD relies heavily on molecular detection of the virus by one-step PCR. These procedures are neither field-usable nor rapid enough considering the speed at which the virus spreads. Thus, development of a rapid, reliable and field-usable diagno...

The baculovirus is a classic example of a parasite that alters the behavior or physiology of its host so that progeny transmission is maximized. Baculoviruses do this by inducing enhanced locomotory activity (ELA) that causes the host caterpillars to climb to the upper foliage of plants. We previously reported that this behavior is not induced in silkworms that are infected with a mutant baculo...

A bicistronic baculovirus expression vector and fluorescent protein-based assays were used to identify the sequences that possess internal translation activity in baculovirus-infected insect cells. We demonstrated that the 5' untranslated region (5'UTR; 473 nucleotides) of Perina nuda virus (PnV) and the 5'UTR (579 nucleotides) of Rhopalosiphum padi virus (RhPV), but not the IRES sequence of Cr...

Timely pond-side detection of white spot syndrome virus (WSSV) plays a critical role in the implementation of bio-security measures to help minimize economic losses caused by white spot syndrome disease, an important threat to shrimp aquaculture industry worldwide. A portable device, namely POCKIT™, became available recently to complete fluorescent probe-based insulated isothermal PCR (iiPCR), ...

Spodoptera exigua microarray was used to determine genes differentially expressed in S. exigua cells challenged with the species-specific baculovirus SeMNPV as well as with a generalist baculovirus, AcMNPV. Microarray results revealed that, in contrast to the host transcriptional shut-off that is expected during baculovirus infection, S. exigua cells showed a balanced number of up- and down-reg...

Insect baculoviruses are capable of infecting mammalian glial cells in the central nervous system. We investigated in the current study the feasibility of using the viruses as toxin gene vectors to eliminate malignant glioma cells in the brain. We first confirmed that glioma cells were permissive to baculovirus infection, with variable transduction efficiencies at 100 viral particles per cell a...
