Colorado potato beetle (Coleoptera : Chrysomelidae) feeding, development, and survival to adulthood after continuous exposure to Bacillus thuringiensis subsp tenebrionis-treated potato foliage from the field

JOURNAL OF ECONOMIC ENTOMOLOGY, 93(1), 149–156.

By: B. Nault n, S. Costa n & G. Kennedy n

author keywords: Colorado potato beetle; Bacillus thuringiensis subsp tenebrionis; feeding; development; survival
MeSH headings : Animals; Bacillus thuringiensis; Coleoptera / growth & development; Coleoptera / physiology; Colorado; Larva / growth & development; Larva / physiology; Pest Control, Biological; Solanum tuberosum
TL;DR: Reduced feeding and poor survival of late instars suggest that counts of large larvae after application do not provide a complete picture of the efficacy of the B. thuringiensis treatment, and development was prolonged in these insects because of ingestion of a sublethal dose of B.Thuringienis.

Variation in performance on cry1Ab-transformed and nontransgenic rice varieties among populations of Scirpophaga incertulas (Lepidoptera : Pyralidae) from Luzon Island, Philippines

JOURNAL OF ECONOMIC ENTOMOLOGY, 93(6), 1773–1778.

By: J. Bentur*, M. Cohen* & F. Gould n

author keywords: Scirpophaga incertulas; Bacillus thuringiensis; rice; resistance management
MeSH headings : Animals; Bacillus thuringiensis / genetics; Bacillus thuringiensis Toxins; Bacterial Proteins / genetics; Bacterial Toxins; Endotoxins / genetics; Female; Hemolysin Proteins; Lepidoptera; Oryza / genetics; Pest Control, Biological; Philippines; Plants, Genetically Modified
TL;DR: Variation in performance under greenhouse conditions among seven populations of Scirpophaga incertulas from Luzon Island, Philippines, on three rice varieties indicated that there was little variation in general vigor among the S.incertulas populations and thus that the variation in performance on cry1Ab-transformed IR58 was probably attributable to differences in susceptibility to Cry1Ab.

Host pubescence and the behavior and performance of the butterfly Papilio troilus (Lepidoptera : Papilionidae)

ENVIRONMENTAL ENTOMOLOGY, 29(2), 299–303.

By: N. Haddad* & W. Hicks

author keywords: Papilio troilus; Sassafras albidum; host preference; landscape variation; oviposition
TL;DR: The negative effects of pubescence on adult oviposition, larval growth rate, and larval survivorship suggest that the population size of P. troilus will reflect availability of nonpubescent hostplants, and may have unintended negative impacts on this butterfly population.
