TL;DR: Both moths had high levels of parasitism on their dominant host plant in the rainy season, yet had low levels of Parasitism on sorghum in the dry season, suggesting that host‐associated differentiation is occurring on this novel introduced crop plant.
Abstract: Diatraea lineolata and Diatraea saccharalis (Lepidoptera: Crambidae) are moths with stemboring larvae that feed and develop on economically important grasses. This study investigated whether these moths have diverged from a native host plant, corn, onto introduced crop plants including sorghum, sugarcane, and rice. Diatraea larvae were collected from these four host plants throughout the year in El Salvador and were reared on artificial diet until moths or parasitoids emerged. Adult moths were subsequently identified to species. Amplified fragment length polymorphisms (AFLPs) and mitochondrial DNA cytochrome oxidase I (COI) were used to examine whether or not there was genetic divergence of D. lineolata or D. saccharalis populations on the four host plants. Percent parasitism was also determined for each moth on its host plants. D. lineolata was collected from corn in the rainy season and sorghum in the dry season. D. saccharalis was most abundant on sugarcane in the rainy season and sorghum in the dry season. The AFLP analysis found two genetically divergent populations of both D. lineolata and D. saccharalis. Both moths had high levels of parasitism on their dominant host plant in the rainy season, yet had low levels of parasitism on sorghum in the dry season. The presence of two genotypes of both Diatraea spp. on sorghum suggest that host-associated differentiation is occurring on this novel introduced crop plant.

TL;DR: The sex pheromone of the female diamondback moth, Plutella xylostella (L.), was isolated and a parapheromonesone was found to be cis -9-tetradecenyl acetate.

TL;DR: The Lepidoptera families are summarized for Mexico, giving known species and what experts estimate to be the true total for each family when all have been described.
Abstract: Being among the most habitat diverse countries in the world (and plant diversity is about 22,000 sp.), Mexico has a Lepidoptera fauna recorded at about 14,385 species but is estimated to be over 22,000 species, if not much higher (some estimates go to 35,000 sp.). High Lepidoptera numbers in Mexico are also due to the large influx of tropical species from the border with Guatemala, as well as Mexican endemics. In this report, the Lepidoptera families are summarized for Mexico, giving known species and what experts estimate to be the true total for each family when all have been described. Many regions of Mexico are still poorly known for smaller moths.
