calling behavior, copulation time, and reproductive compatibility of corn-strain fall armyworm (lepidoptera: noctuidae) from populations in mexico.the calling behavior, mating time, and the reproductive compatibility of virgin adults of fall armyworms, spodoptera frugiperda (j. e. smith), were studied in this work. larvae were collected on maize (zea mays l.) from six states located on the pacific coast (chiapas, michoacán, and sinaloa), on the gulf of mexico (veracruz and yucatan), and in central mexico (morelos). before the experiments, insects were reared under laboratory conditions for one generation. we recorded the age at which femal ...201728881955
maize diversity and ethnolinguistic diversity in chiapas, mexico.the objective of this study is to investigate whether ethnolinguistic diversity influences crop diversity. factors suggest a correlation between biological diversity of crops and cultural diversity. although this correlation has been noted, little systematic research has focused on the role of culture in shaping crop diversity. this paper reports on research in the maya highlands (altitude >1,800 m) of central chiapas in southern mexico that examined the distribution of maize (zea mays) types am ...200515640353
impact of a nucleopolyhedrovirus bioinsecticide and selected synthetic insecticides on the abundance of insect natural enemies on maize in southern mexico.the impact of commonly used organophosphate (chlorpyrifos, methamidophos), carbamate (carbaryl), and pyrethroid (cypermethrin) insecticides on insect natural enemies was compared with that of a nucleopolyhedrovirus (baculoviridae) of spodoptera frugiperda (j. e. smith) (lepidoptera noctuidae) in maize grown in southern mexico. analyses of the selectv and koppert side effects (iobc) databases on the impact of synthetic insecticides on arthropod natural enemies were used to predict approximately 7 ...200312852601
