    Maintaining and Improving Habitat for Hummingbirds in Oklahoma and Texas

    United States Department of Agriculture Maintaining and Improving Habitat for Hummingbirds in Oklahoma and Texas A Land Manager’s Guide Forest Service National Headquarters Introduction Hummingbirds play an important role in the food web, pollinating a variety of flowering plants, some of which are specifically adapted to pollination by hummingbirds. Some hummingbirds are at risk, like other pollinators, due to habitat loss, changes in the distribution and abundance of nectar plants (which are affected by climate change), the spread of invasive Anna’s Hummingbird Nest plants, and pesticide use. This guide is intended to Courtesy of Steve Berardi Wikimedia Commons help you provide and improve habitat for humming- birds, as well as other pollinators, in Oklahoma and Texas. While hummingbirds, like all birds, have the basic habitat needs of food, water, shelter, and space, this guide is focused on providing food—the plants that provide nectar for hummingbirds. Because climate, geology, and vegetation vary widely in different areas, specific recommenda- tions are presented for each ecoregion in Oklahoma and Texas. (See the Ecoregions in Oklahoma and Texas section, below.) This guide also provides brief descriptions of the species that visit Oklahoma and Texas, as well as some basic information about hummingbird habitat needs. Whether you’re involved in managing public or private lands, large acreages or small areas, you can make them attractive to our native hummingbirds. Even long, narrow pieces of habitat, like utility corridors, field edges, and roadsides, can provide important connections among larger habitat areas. Hummingbird Basics Some of the hummingbird species of Okla- homa and Texas are migratory, generally wintering in Mexico and southern Texas and pushing northward through Nevada and California for summer breeding.

    ABSTRACT MITCHELL III, ROBERT DRAKE. Global Human Health Risks for Arthropod Repellents or Insecticides and Alternative Control Strategies. (Under the direction of Dr. R. Michael Roe). Protein-coding genes and environmental chemicals. New paradigms for human health risk assessment of environmental chemicals emphasize the use of molecular methods and human-derived cell lines. In this study, we examined the effects of the insect repellent DEET (N, N-diethyl-m-toluamide) and the phenylpyrazole insecticide fipronil (fluocyanobenpyrazole) on transcript levels in primary human hepatocytes. These chemicals were tested individually and as a mixture. RNA-Seq showed that 100 µM DEET significantly increased transcript levels for 108 genes and lowered transcript levels for 64 genes and fipronil at 10 µM increased the levels of 2,246 transcripts and decreased the levels for 1,428 transcripts. Fipronil was 21-times more effective than DEET in eliciting changes, even though the treatment concentration was 10-fold lower for fipronil versus DEET. The mixture of DEET and fipronil produced a more than additive effect (levels increased for 3,017 transcripts and decreased for 2,087 transcripts). The transcripts affected in our treatments influenced various biological pathways and processes important to normal cellular functions. Long non-protein coding RNAs and environmental chemicals. While the synthesis and use of new chemical compounds is at an all-time high, the study of their potential impact on human health is quickly falling behind. We chose to examine the effects of two common environmental chemicals, the insect repellent DEET and the insecticide fipronil, on transcript levels of long non-protein coding RNAs (lncRNAs) in primary human hepatocytes.

    11th International Working Conference on Stored Product Protection Biology and biointensive management of Acanthoscelides obtectus (Say) (Coleoptera: Chrysomelidae) – a pest of kidney beans wordwide Thakur, D.R.*#, Renuka Department of Biosciences, Himachal Pradesh University, Summerhill, Shimla 171005, India *Corresponding author, Email: [email protected], [email protected] #Presenting author, Email: [email protected] [email protected] DOI: 10.14455/DOA.res.2014.24 Abstract Insects in the family Bruchidae are commonly called “pulse weevils” and are cosmopolitan in distribution. These beetles cause serious economic loss of legume commodities both in fields and every year. Pulses constitute the main source of protein for developing countries like India where per capita consumption of animal protein is very low. Due to their high protein quantity and quality, legumes are considered as “poor man‟s meat”. A large number of non-native pulse beetles have crossed geographical boundaries and becoming cosmopolitan in distribution, thus posing major pest problem worldwide. A kidney bean pest, Acanthoscelides obtectus (Say) (Coleoptera: Chrysomelidae) native to Central and Southern America has recently infested stored kidney beans in the Indian subcontinent. The present investigations determined life cycle, behaviour, facundity, pest status, host range and developmental compatibility on diffent legumes and different cultivars of kidney beans. Acetone and alcoholic extracts of some botanicals have been tested and proved effective to suppress facundity, egg hatch and adult longivity of the pest population under laboratory conditions. Keywords: Acanthoscelides obtectus, biology, resistance, developmental compatiblity, botanical management 1. Introduction Most pulses have 17-24% protein content which are 2.3 times higher than traditional cereals. Any stored materials of plant origin are vulnerable to attack by insect pests if the pulses are dried and stored improperly.

Plants in the neotropical region provide different ecological services and sustain entomofauna biodiversity. The butterfly, Morpho helenor montezuma, has high economic value worldwide, derived from recreational activities. To enhance its sustainable use, it is important to know the spatial relationship of this species with its host-plants. Objective. To estimate the potential geographical areas in Mexico of three host-plants: Bauhinia divaricata, Andira inermis and Pterocarpus rohrii and their spatial relationship with M. helenor montezuma. Methodology. Distribution models of the species were generated using MaxEnt, employing predictive variables based on temperature and precipitation, and records of presence data. Subsequently, a joint analysis of layers was performed to determine the overlap in the distributions. Results. The models were appropriate as the area under the curve ranged from 0.86 to 0.96. The broadest potential host-plant distribution was for B. divaricata (30%), followed by A. inermis (21%) and P.

Southgate Biology Department, Pest Infestation Control Laboratory, Ministry of Agriculture, Fisheries, and Food, Slough SL3 7HJ, Berks, England INTRODUCTION Species of Bruchidae breed in every continent except Antarctica. The larg­ est number of species live in the tropical regions of Asia, Africa, and Central and South America. Many species have obvious economic importance because they breed on grain legumes and consume valuable proteins that would otherwise be eaten by man. Other species, however, destroy seeds of an immense number of leguminous trees and shrubs, which, though they have no obvious economic value, stem the advance of the deserts into the marginal cultivated areas of the world. When this ecosystem is mismanaged by practices such as over­ grazing, then any organism that restricts the normal regeneration of seed­ lings will, in the long run, affect agriculture adversely. This has been demonstrated recently in some African and Middle Eastern semiarid zones (65). The present interest in the management of arid areas and in the introduc­ Annu. Rev.

It has also emphasized the inadequacy of our knowledge of the taxonomy and biology of these beetles.

  • Wikipedia Beetles Dung Beetles Are Beetles That Feed on Feces

    Wikipedia Beetles Dung Beetles Are Beetles That Feed on Feces

    Wikipedia beetles Dung beetles are beetles that feed on feces. Some species of dung beetles can bury dung times their own mass in one night. Many dung beetles, known as rollers , roll dung into round balls, which are used as a food source or breeding chambers. Others, known as tunnelers , bury the dung wherever they find it. A third group, the dwellers , neither roll nor burrow: they simply live in manure. They are often attracted by the dung collected by burrowing owls. There are dung beetle species of different colours and sizes, and some functional traits such as body mass or biomass and leg length can have high levels of variability. All the species belong to the superfamily Scarabaeoidea , most of them to the subfamilies Scarabaeinae and Aphodiinae of the family Scarabaeidae scarab beetles. As most species of Scarabaeinae feed exclusively on feces, that subfamily is often dubbed true dung beetles. There are dung-feeding beetles which belong to other families, such as the Geotrupidae the earth-boring dung beetle. The Scarabaeinae alone comprises more than 5, species. The nocturnal African dung beetle Scarabaeus satyrus is one of the few known non-vertebrate animals that navigate and orient themselves using the Milky Way. Dung beetles are not a single taxonomic group; dung feeding is found in a number of families of beetles, so the behaviour cannot be assumed to have evolved only once. Dung beetles live in many habitats , including desert, grasslands and savannas , [9] farmlands , and native and planted forests. They are found on all continents except Antarctica. They eat the dung of herbivores and omnivores , and prefer that produced by the latter.
