Most of the viral vectors were constructed using (1) the Autographa californica nuclear polyhedrosis virus (AcNPV), which is able to infect moth species, Spodoptera frugiperda ovarian cell lines and, in specific conditions, Drosophila cells (2) the Bombyx mori nuclear polyhedrosis virus (BmNPV), which is able to infect silkworm cells. To broaden the range of infection of hosts, a hybrid virus was generated [118,119].

Baculoviruses are members of a large group of double-stranded DNA viruses which only infect invertebrates, including insects. The restricted host range makes baculoviruses safer than mammalian expression systems. The most widely used baculoviruses are Autographa califor-nica nuclear polyhedrosis virus and the Bombyx mori nuclear polyhedrosis virus. The host cell most commonly used is Sf9, derived from the fall army worm Spodoptera frugiperda. 

Spodoptera frugiperda IPLB-Sf21-AE cell line, simply named Sf21, was originally established by Vaughn et al. in 1977. Sf9 is a clone derived from Sf21 by the same authors [51].

Sf-9 cells are derived from the IPLBSF-21 cell line, isolated by Vaughn et al. (1977) from pupal ovarian tissue of the fall armyworm Spodoptera frugiperda. This cell line is commonly used for bioproduct expression employing baculovirus as vectors, similarly to the High-Five cell line.

In a study carried out by Castro et al. (1997), the authors evaluated the susceptibility of four different lepidopteran cell lines to AgMNPV virus. Anticarsia gemmatalis (UFL-AG-286) and Spodoptera frugiperda (IPLBSF-21) infected cells were productive, whereas Choristoneura fumi-ferana (IPRI-CF-124T) and Bombyx mori (BM-5) infected cells were abortive. 

Other examples of in vitro baculovirus systems (virus-cell line) are Helicoverpa armigera SNPV and Helicoverpa zea cells, with 222 polyhe-dra per cell (Lua et ah, 2002) Trichoplusia ni NPV and Trichoplmia ni cells, with 70 polyhedra per cell (Potter et ah, 1976) Lymantria dispar MNPV and Lymantria dispar cells, with 57 polyhedra per cell (Slavicek et al., 1996) Spodoptera frugiperda MNPV and Spodoptera frugiperda, with 399 polyhedra per cell (Almeida et al., 2005).
