TL;DR: The Pyralidae Pyraustinae of the Galapagos Islands are diagnosed and illustrated and their biology and distribution are discussed in this paper, where they are considered as new and described.
Abstract: The Pyralidae Pyraustinae of the Galapagos Islands are diagnosed and illustrated and their biology and distribution are discussed. Of the five species recorded, three are considered as new and described: Neohelvibotys hoecki sp. n., Pyrausta galapagensis sp. n., and Pyrausta insolata sp. n.
92 citations
TL;DR: Data demonstrate that N. pyrausta continues to be present and fluctuate in populations of O. nubilalis as it has since its discovery in the US and the dynamics of its presence remain similar through changes in corn production including crop rotations, reduced tillage and transgenic insect-resistant varieties.
65 citations
TL;DR: Adult longevity, oviposition, fecundity and fertility were adversely affected by infection with Nosema pyrausta, and Reproduction of infected moths was 39.3% lower than that of moths with no detectable infection, and heavily infected moth had 52.0% lower reproduction.
54 citations
TL;DR: Sublethal and lethal effects of Nosema pyrausta were evaluated in a series of experiments with both field-collected and laboratory populations of Ostrinia nubilalis, finding mortality was linked to the ovipositional sequence of the egg masses and cold stress and crowding stress increased mortality of infected larvae.

TL;DR: Intraplant epizootics of entomopathogens,Beauveria bassiana (Balsamo) Vuillemin, andNosema pyrausta (Paillot) were studied in a corn and significantly reduced tunneling by the filial generation of the European corn borer.
Abstract: Intraplant epizootics of entomopathogens,Beauveria bassiana (Balsamo) Vuillemin, andNosema pyrausta (Paillot) were studied in a corn,Zea mays L., agroecosystem. Egg masses of the European corn borer,Ostrinia nubilalis (Hubner), infected withN. pyrausta were placed on midwhorl-stage corn plants. Conidia ofB. bassiana were applied in an aqueous suspension. Frass from the initial insects remaining within the plants was contaminated with sufficientN. pyrausta spores to infest 80% of the filial generation in each year of a 2-yr study. Viability ofN. pyrausta within the frass was monitored throughout the winter. Potential for impact of this inoculum on the filial generation is discussed. Conidia from cadavers of the European corn borer that were killed by the initial inoculum ofB. bassiana and/or conidia from the initial inoculum ofB. bassiana significantly reduced tunneling by the filial generation of the European corn borer. However, neither the concentration ofB. bassiana nor the age of the larvae exposed toB. bassiana, had any significant (P<.05) effect on tunneling by the 2nd-generation larvae.
