An Invitation To Measure Insect Cold Tolerance: Methods, Approaches, And Workflow., Brent J Sinclair, Litza E Coello Alvarado, Laura V Ferguson
An Invitation To Measure Insect Cold Tolerance: Methods, Approaches, And Workflow., Brent J Sinclair, Litza E Coello Alvarado, Laura V Ferguson
Biology Publications
Insect performance is limited by the temperature of the environment, and in temperate, polar, and alpine regions, the majority of insects must face the challenge of exposure to low temperatures. The physiological response to cold exposure shapes the ability of insects to survive and thrive in these environments, and can be measured, without great technical difficulty, for both basic and applied research. For example, understanding insect cold tolerance allows us to predict the establishment and spread of insect pests and biological control agents. Additionally, the discipline provides the tools for drawing physiological comparisons among groups in wider studies that may …

Abejas Silvestres (Himenóptera: Apoidea) En La Neblina: Análisis De La Diversidad, Interacciones, Y Potencial Para Miel En Un Remanente De Bosque Nublado, Jen Hayes
Independent Study Project (ISP) Collection
Las abejas (Himenóptera: Apoidea) se encuentran en casi cada una de las bioregiones en el mundo. Su composición es muy diversa en los neotrópicos. Las abejas silvestres (no-Apis) representan casi el 90% de las especies de abejas en todo el mundo (Parra, 2005). Los objetivos principales de este estudio fueron realizar un inventario de las especies de abejas al final de la estación seca, observar sus interacciones intra-específicas, y determinar el potencial de producción de miel medicinal de las abejas sin aguijón (Apidae: Meliponini). El estudio fue realizado en la Reserva Inti Llacta, un remanente de bosque nublado …

This fact sheet provides information on the rose stem girdler, a common cane-boring beetle of raspberry and blackberry plants in northern Utah. It includes a description, host plants, life history, monitoring and thresholds, and management strategies.
Ec86-1548 Common Insect Pests Of Trees In The Great Plains, Mary Ellen Dix, Judith E. Pasek, Mark O. Harrell, Frederick P. Baxendale
Ec86-1548 Common Insect Pests Of Trees In The Great Plains, Mary Ellen Dix, Judith E. Pasek, Mark O. Harrell, Frederick P. Baxendale
Judith E Pasek
This publication was developed by entomologists on the Pest Management Task Force of the Great Plains Agricultural Council Forestry Committee to provide the public and professionals with information needed to identify and manage common insect pests of trees in the Great Plains. It is designed for those with no formal training in entomology and is not intended to summarize everything known about a particular insect.
Insecticide Resistance In The Bed Bug Comes With A Cost, Jennifer R. Gordon, Michael F. Potter, Kenneth F. Haynes
Insecticide Resistance In The Bed Bug Comes With A Cost, Jennifer R. Gordon, Michael F. Potter, Kenneth F. Haynes

Adaptation to new environmental stress is often associated with an alteration of one or more life history parameters. Insecticide resistant populations of insects often have reduced fitness relative to susceptible populations in insecticide free environments. Our previous work showed that three populations of bed bugs, Cimex lectularius L., evolved significantly increased levels of resistance to one product containing both β-cyfluthrin and imidacloprid insecticides with only one generation of selection, which gave us an opportunity to explore potential tradeoffs between life history parameters and resistance using susceptible and resistant strains of the same populations. Life history tables were compiled by collecting …
Nutrition Regulation Of Male Accessory Gland Growth And Maturation In Tribolium Castaneum, Jingjing Xu, Ashlee L. Anciro, Subba R. Palli
Nutrition Regulation Of Male Accessory Gland Growth And Maturation In Tribolium Castaneum, Jingjing Xu, Ashlee L. Anciro, Subba R. Palli
Entomology Faculty Publications
Insulin/IGF-1 signaling (IIS) pathway is known to control growth, development and reproduction. Insulin-like peptide mediated body size plasticity in Drosophila melanogaster has been reported. Here, our studies showed that IIS pathway and nutrition regulate growth and maturation of the male accessory gland (MAG) in the red flour beetle, Tribolium castaneum. The size of MAG increased from day 1 to day 5 post-adult emergence (PAE). This increase in the size of MAG is contributed by an increase in cell size, but not cell number. The growth of MAG was impaired after double-stranded RNA (dsRNA)-mediated knockdown in the expression of genes …
Infestation Of Aetalion Reticulatum (Linnaeus) (Hemiptera: Aethalionidae) In Plants Of Euterpe Oleracea Martius (Arecaceae) In Acre State, Brazil, Rodrigo Souza Santos Rss
Infestation Of Aetalion Reticulatum (Linnaeus) (Hemiptera: Aethalionidae) In Plants Of Euterpe Oleracea Martius (Arecaceae) In Acre State, Brazil, Rodrigo Souza Santos Rss

The açai palm (Euterpe oleracea Martius) is a native palm tree from the Amazon region floodplains and may be indicated as the most economically profitable species of this genus. Its fruit pulp is extracted and widely consumed by the population of northern Brazil in several ways. With the expansion of the planted area many factors may affect the production and limit the cultivation, highlighting the occurrence of insect pests that cause losses in production. This report presents the first occurrence of the leafhopper Aetalion reticulatum (Linnaeus) (Hemiptera: Auchenorrhyncha: Aethalionidae) in E. oleracea plants. The occurrence of this insect associated with …
