Characterization of Solenopsis invicta (Hymenoptera: Formicidae) populations in Virginia: social form genotyping and pathogen/parasitoid detection
(Florida Entomological Society, 2010-03)
Red imported fire ant, Solenopsis invicta Buren, workers were sampled from 26 colonies in Virginia during the 2007-2008 time period. Polymerase chain reaction (PCR) assays were used to determine colony social form (monogyny ...
Toxicity and field efficacy of four neonicotinoids on harlequin bug (Hemiptera: Pentatomidae)
(Florida Entomological Society, 2012-12)
Harlequin bug, Murgantia histrionica (Hahn), is a pest of cole crops in the USA. Laboratory toxicity assays revealed that the neonicotinoid insecticides imidacloprid, thiamethoxam, dinotefuran, and clothianidin are toxic ...
Distribution of Cotesia rubecula (Hymenoptera: Braconidae) and its displacement of Cotesia glomerata in eastern North America
(Florida Entomological Society, 2012-06)
A survey was conducted from May to Oct of 2011 of the parasitoid community of the imported cabbageworm, Pieris rapae (Lepidoptera: Pieridae), in cole crops in part of the eastern United States and southeastern Canada. The ...
Spread of Larinus minutus (Coleoptera: Curculionidae), a biological control agent of knapweeds, following introduction to northwestern Arkansas
(Florida Entomological Society, 2016-12)
Spotted knapweed, Centaurea stoebe L. (Asteraceae), is an invasive perennial forb that has become economically and ecologically damaging in North America. The weevil Larinus minutus Gyllenhal (Coleoptera: Curculionidae), ...
Characterization of sounds in maize produced by internally feeding insects: investigations to develop inexpensive devices for detection of Prostephanus truncatus (Coleoptera: Bostrichidae) and Sitophilus zeamais (Coleoptera: Curculionidae) in small-scale storage facilities in sub-Saharan Africa
(Florida Entomological Society, 2015-06)
Infestations by Prostephanus truncatus Horn (Coleoptera: Bostrichidae) and Sitophilus zeamais Motschulsky (Coleoptera: Curculionidae) are prevalent in small-scale Zea mays L. storage facilities in Tanzania and other regions ...
Difference in the abundance of scale insect parasitoids among four cardinal directions
(Florida Entomological Society, 2016-12)
We conducted a study to assess the potential differences in the abundances of hymenopteran parasitoids among cardinal directions. Experiments were conducted on scale insect-infested willow oak trees in the urban landscapes ...
Arm-specific dynamics of chromosome evolution in malaria mosquitoes
(BMC, 2011)
Background: The malaria mosquito species of subgenus Cellia have rich inversion polymorphisms that correlate with environmental variables. Polymorphic inversions tend to cluster on the chromosomal arms 2R and 2L but not ...
Differing house Finch cytokine expression responses to Original and evolved isolates of Mycoplasma gallisepticum
(Frontiers Media, 2018-01-22)
The recent emergence of the poultry bacterial pathogen Mycoplasma gallisepticum (MG) in free-living house finches (Haemorhous mexicanus), which causes mycoplasmal conjunctivitis in this passerine bird species, resulted in ...
Proteogenomic Analysis of Protein Sequence Alterations in Breast Cancer Cells
(Nature Research, 2019-07-18)
Cancer evolves as a result of an accumulation of mutations and chromosomal aberrations. Developments in sequencing technologies have enabled the discovery and cataloguing of millions of such mutations. The identification ...
Red imported fire ants (Hymenoptera : Formicidae) increase the abundance of aphids in tomato
(Florida Entomological Society, 2007-09)
Red imported fire ants, Solenopsis invicta (Buren) (Hymenoptera: Formicidae), are abundant in many agroecosystems in the southern United States and can affect the abundance of arthropods in these systems. We determined the ...
