Food Insecurity is Associated with Low Dietary Diversity in Rural Women in Mexico: Results from the Mexican National Health and Nutrition Survey, ENSANUT 2018.

Rural women suffer greater vulnerability to food insecurity (FI) compared to their urban or male counterparts. We analyzed the association between food security (FS) status and dietary diversity (DD) in rural women through data from the Mexican National Health and Nutrition Survey (ENSANUT) 2018 from 2,099 rural women. DD was measured using a semi-quantitative food frequency questionnaire.

Age matters: variations in parasitoid diversity along a successional gradient in a dry semi-deciduous tropical forest.

Parasitoids are an important group of insects because their species number is among the highest. Multiple studies have addressed the relationships between forest successional age and insect diversity by focusing on herbivorous organisms, but changes in diversity of parasitoids are still poorly known. This work analyses the diversity of parasitoids in tropical forests representing three successional stages.

Survival Rate of the Neotropical Stingless Bees and after Exposure to Five Selected Insecticides, under Controlled Conditions.

Insecticides used in agricultural pest management pose survival risks to the stingless bees that forage on crops in tropical and subtropical regions. In the present study, we evaluated, under laboratory conditions, the acute oral toxicity of five selected insecticides (dinotefuran, imidacloprid, flupyradifurone, spirotetramat, and cyantraniliprole) to two species of neotropical stingless bees: and . At field recommended doses, dinotefuran, imidacloprid, and flupyradifurone caused the highest mortality in both bee species.

Description of the female of González-Moreno & Bordera, 2015 (Hymenoptera, Ichneumonidae, Labeninae), with new records of species from Mexico.

The female of Labena madoricola González-Moreno & Bordera, 2015 is described and illustrated for the first time from material collected with Malaise traps in 2016 in the Biocultural Reserve Kaxil Kiuic, Yucatán, Mexico. Diagnostic characters to distinguish females of New World Labena are provided. New distribution records of Labena species in Yucatán Peninsula, are also reported.

Description of three new species of Labena Cresson from Mexico (Hymenoptera, Ichneumonidae, Labeninae), with notes on tropical species richness.

Three new species of Labena Cresson (Ichneumonidae, Labeninae); L. littoralis sp. nov.

The species of the Neotropical genus Fractipons Townes, 1970 (Hymenoptera, Ichneumonidae, Cryptinae).

In this paper, two new species of the Neotropical genus Fractipons Townes, 1970 (Hymenoptera, Ichneumonidae) are described. A new diagnosis for the genus, a re-description of Fractipons cincticornis Townes, 1970 and a key to known species are provided. New distribution records for the genus now include Argentina, Costa Rica, Panama and Peru.
