TL;DR: Commercial sales of TC1507 maize in Puerto Rico have been stopped pending potential reversion to susceptibility, and laboratory bioassays showed that S. frugiperda collected from the affected area exhibited lower sensitivity to the Cry1F protein compared with typical colonies from other regions.
Abstract: Transgenic maize, Zea mays L., event TC1507 produces the Cry1F protein to provide protection from feeding by several important lepidopteran pests, including Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae). Reports of reduced field performance against this species in Puerto Rico were investigated, and laboratory bioassays showed that S. frugiperda collected from the affected area exhibited lower sensitivity to the Cry1F protein compared with typical colonies from other regions. The resistance was shown to be autosomally inherited and highly recessive. The Puerto Rico colony was shown to be moderately less sensitive than susceptible laboratory strains to Cry1Ab and Cry1Ac, but the differences in sensitivity were dramatically smaller than for Cry1F. Potential contributory factors to the emergence of resistance to Cry1F in Puerto Rico populations of S. frugiperda include the tropical island geography, unusually large population sizes in 2006, and drought conditions reducing the availability of alternative hosts. In response to this resistance incident, the technology providers have stopped commercial sales of TC1507 maize in Puerto Rico pending potential reversion to susceptibility.

TL;DR: A pheromone biosynthesis activating neuropeptide (PBAN) hormone was identified from the brain-subesophageal ganglion complexes of the adult corn earworm, Heliothis zea, and induced production of a normal quantity of sex pherOMone in ligated H. zea females, indicating that this or similar peptides may be responsible for the regulation of phersomone production in moths.
Abstract: A pheromone biosynthesis activating neuropeptide (PBAN) hormone that controls sex pheromone production in female moths was identified from the brain-subesophageal ganglion complexes of the adult corn earworm, Heliothis zea. PBAN has 33 amino acid residues and a molecular weight of 3900. Its amino acid sequence has no significant homology with any of the fully characterized peptide hormones. The synthetic peptide, at a dose of between 2 and 4 picomoles, induced production of a normal quantity of sex pheromone in ligated H. zea females. The peptide also induced pheromone production in six other species of moths, thus indicating that this or similar peptides may be responsible for the regulation of pheromone production in moths.

TL;DR: The first occurrence, in Brazil, of Helicoverpa armigera (Hubner) (Lepidoptera: Noctuidae), which was considered up till now a quarantine pest, is reported.
Abstract: In this study is reported the first occurrence, in Brazil, of Helicoverpa armigera (Hubner) (Lepidoptera: Noctuidae), which was considered up till now a quarantine pest. The notification occurred in the Goias State, in soybean; Bahia State, in volunteer soybean; and Mato Grosso State, in cotton.
