Effects of Diflubenzuron When Fed to Adult Female Alfalfa WeevilsMiddib, Mohamed M. 01 January 1984 (has links)
The purpose of this project was to evaluate dif1ubenzuron ovicidal effects on adult female alfalfa weevils Hypera postica in the laboratory. There was little relationship of weevil mortality to dosage or length of exposure of the adult to the chemical. An indirect result of dif1ubenzuron was an increase in muscardine fungus (Beauveria Sp.). Other effects of the chemical on the adults were yellow deposits and tissue extending from the tip of the abdomen.
The main effect of di1fubenzuron when fed to female alfalfa weevils was on the eggs. The effects were dosage related, especially on eggs viability. The viability was dropped from 99% in the control to 38.9% on the treated insects in ten days using the highest dosage. Another effect of diflubenzuron on alfalfa weevil eggs was on the shape of the eggs. The treated insects laid longer and lighter color eggs.

A Multi-locus Molecular Phylogeny of the Core Genera of Ellescini (Coleoptera: Curculionidae: Curculioninae) with a Review of the Species of Ellescus in North AmericaLewis, Jake 30 March 2022 (has links)
A combination of morphological and molecular techniques were used to investigate the taxonomy of th species of Ellescus Dejean, 1821 in North America (Curculionidae: Curculioninae: Ellescini), as well as investigate the phylogenetic relationships amongst genera within the tribe Ellescini. Four valid species of Ellescus were documented from the Nearctic Region. These include the temperately distributed E. michaeli n. sp., the west coast endemic species E. californicus (Casey, 1885) (resurrected from synonymy with E. ephippiatus (Say, 1831)), the widespread, hypervariable E. ephippiatus, and the Holarctic E. bipunctatus (Linnaeus, 1758) (of which E. borealis (Carr, 1920) is found to be a junior synonym). The European species, E. scanicus (Paykull, 1792), is determined to have been erroneously reported from North America. The Maximum Likelihood and Bayesian Inference analyses based on CO1, CytB, 28S, and 16S sequence data found moderate to strong support for the monophyly of Ellescus and moderate to strong support for Proctorus LeConte, 1876 as a lineage nested within Dorytomus Germar, 1817. The genera Proctorus and Rodotymus Zumpt, 1932 are placed in synonymy under Dorytomus.
