We describe a new species of Dipetalonema occurring in the body cavity of Ateles chamek (Humboldt, 1812) from north-central Bolivia. Morphologic characters serving to separate Dipetalonema yatesi n. sp. from known forms include a vagina vera with a simple tube and thin walls and a left spicule, which possesses a handle shorter than the lamina (ratio 2.7); the latter displays an anterior membran...

Mites of the genus Rhizoglyphus (Acari: Acaridae) are serious pests plants belonging to orders Liliales and Asparagales such as onions, garlic, lilies, tulips. Their control by synthetic pesticides is becoming problematic a result resistance development in these mites environmental health issues. New pest methods thus need be developed. This review provides an overview studies related bulb mite...

The conditional expression of alternative phenotypes underlies the production of almost all life history decisions and many dichotomous traits, including male alternative reproductive morphs and behavioral tactics. Changes in tactic fitness should lead to evolutionary shifts in developmental switch points that underlie tactic expression. We used experimental evolution to directly test this hypo...
