(2) We detail the fatty acid compositions of last larval instars of two lepidopterans, Spodoptera frugiperda and Trichoplusia ni, two tissues from T. ni, a cell line derived from each species and the respective larval and cell culture media.
(3) toxins having activities specific to lepidopteran species showed that several domains were highly homologous.
(4) Late stationary phase Bacillus megaterium cells harboring the cloned B. thuringiensis cryBI gene contained large aggregates of the P2 protein, and the cells were highly toxic to both lepidopteran and dipteran larvae.

(6) The chromatin of the lepidopteran Ephestia kuehniella was digested by micrococcal nuclease, DNase I and S1-nuclease combined with DNase I pretreatment.
(7) kurstaki were compared against four species of defoliating forest lepidopterans in diet-incorporation assays.
(8) Mutagenesis has been used to investigate the toxicity and specificity of a larvicidal protein from Bacillus thuringiensis aizawai IC1 that is toxic to both lepidoptera and diptera and differs by only three residues from a monospecific lepidopteran toxin from B. thuringiensis berliner.
(9) The lepidopteran-specific preparation (trypsin-treated protoxin containing 58 and 55 kDa polypeptides) bound to two membrane proteins in the lepidopteran cells but none in the dipteran cells.
(10) These acylpolyamines instantly paralyze lepidopteran larvae following injection.
(11) A persistent infection by a baculovirus-like particle was found in the established lepidopteran (Heliothis zea) cell line, IMC-HZ-1.
(12) This finding suggests the existence of a new type of juvenile peptide hormone in lepidopteran insects.
(13) Autographa californica nuclear polyhedrosis virus (AcMNPV) is a large, double-stranded DNA virus of lepidopteran insects.
(14) Tolerance for such change is attributed to the holokinetic organisation of lepidopteran chromosomes.
(15) A number of additional granulin and lepidopteran polyhedrin sequences will certainly be forthcoming because of the ease with which these genes are identified by cross-hybridization with available related probes.
(16) These coleopteran proteins also showed some sequential homology but no immunological cross-reactivity with storage proteins from the lepidopterans Galleria mellonella and Heliothis virescens.
(17) The previously unreported format, termed affinity-amplified immunoassay (AAIA), was successfully used for quantitative monitoring of low levels of the esterase in dilute hemolymph and egg homogenates from various lepidopteran insect species, as well as for detection of the native and mutant forms of the enzyme obtained in a recombinant baculovirus expression system.
(18) Cell lines established from the Lepidopteran insect Spodoptera frugiperda (e.g., Sf9) are used routinely as hosts for the expression of foreign proteins by baculovirus vectors.
