Background Understanding mosquito biting behaviours is important for designing and evaluating protection methods against nuisance biting and mosquito-borne diseases (e.g. dengue, malaria and zika). We investigated the preferred biting sites by Aedes aegypti and Anopheles arabiensis on adult volunteers in standing or sleeping positions; and estimated the theoretical protection limits affordable from protective clothing or repellent-treated footwear. Methods Adult volunteers dressed in shorts and t-shirts were exposed to infection-free laboratory-reared mosquitoes inside screened chambers from 6am to noon (for day-biting Ae. aegypti) or 6pm to midnight (night-biting An. arabiensis). Attempted bites on different body parts were recorded. Comparative observations were …

Toxicity And Repellency Of Plant Extract And Termiticide Against Fungus Growing Subterranean Termites (Blattodea: Termitidae), Muhammad Shahid Nisar, Talha Nazir, Shah Zaman, Syed Ismat Hussain, Nasir Ahmad Khan, Hafiz Muhammad Usman Aslam, Wajad Nazeer, Muhammad Akhtar

Journal of Bioresource Management

Different methods such as physical, biological and chemical are used to manage soil fungus increasing termites. Synthetic insecticide plays a vital part in the management of termites. The pesticide used in big quantities causes phytotoxicity, mammalian toxicity and resistance to pesticides in target pests and insect outbreaks. Intensive pesticides exert chronic effects on living organisms with annoyance for beneficial insects. It also accompanied with environmental hazards and developed resistance. Plant leaves extracts provide a distinct variety of biochemical compounds with diverse prospective uses. Resistance development requires the discovery of fresh biological compounds with a wide spectrum of action. Plant leaves …

Effects Of Color Attributes On Trap Capture Rates Of Chrysobothris Femorata (Coleoptera: Buprestidae) And Related Species, Cynthia L. Perkovich, Karla M. Addesso, Joshua P. Basham, Donna C. Fare, Nadeer N. Youssef, Jason B. Oliver

Agricultural and Environmental Sciences Faculty Research

Chrysobothris spp. (Coleoptera: Buprestidae) and other closely related buprestids are common pests of fruit, shade, and nut trees in the United States. Many Chrysobothris spp., including Chrysobothris femorata, are polyphagous herbivores. Their wide host range leads to the destruction of numerous tree species in nurseries and orchards. Although problems caused by Chrysobothris are well known, there are no reliable monitoring methods to estimate local populations before substantial damage occurs. Other buprestid populations have been effectively estimated using colored sticky traps to capture beetles. However, the attraction of Chrysobothris to specific color attributes has not been directly assessed. A multi-color trapping …

LSU Doctoral Dissertations

The corn earworm, Helicoverpa zea (Boddie), is a target pest of Bacillus thuringiensis (Bt) maize and cotton in the U.S. Previous studies have reported that this pest has developed field resistance to pyramided Cry1A/Cry2A maize and cotton in certain areas of the southern United States. The objectives of this study were to 1) determine the current status and distribution of the resistance to Cry1A.105 and Cry2Ab2 in H. zea in the southeastern United States; 2) estimate the resistance allele frequencies to the two Bt proteins in H. zea field populations in the region, and 3) assess the inheritance of the …

Ant Cuticle Microsculpture: Diversity, Classification, Evolution, And Function, John Paul Hellenbrand

Master of Science in Integrative Biology Theses

My thesis covers the intricacies of ant microsculpture diversity, classification, evolution and function. To do this, the thesis is organized into two chapters. The first chapter is a review of ant cuticle and microsculpture diversity as well as including analyses examining the evolution and lability of microsculpture traits. I then review the literature for functional hypotheses related to ant microsculpture. The second chapter explores the relationship of microsculpture and important morphological, physiological, and ecological traits to evaluate support for functional hypotheses.

A New Species Of Epeolus Latreille, 1802 (Hymenoptera: Apidae) From Western North America, Thomas M. Onuferko, Cory S. Sheffield

Insecta Mundi

A new species of Epeolus Latreille, 1802 (Hymenoptera: Apidae)—E. emiliae Onuferko and Shef­field, new species—is described from North America west of the Great Plains. It is morphologically most similar to Epeolus autumnalis Robertson, 1902, a species known exclusively from east of the Rocky Moun­tains. DNA barcode sequences from representatives of E. autumnalis and E. emiliae share a barcode index number (i.e., BIN: BOLD:AAF2361), but the two species exhibit marked and consistent differences in integu­ment coloration and the patterns of pubescence on the metasoma, and their distributional ranges, based on known specimens, show no overlap. This discovery increases …

Disturbance Ecology Of The Sonadora River Rock Pool Insect Assemblage At Luquillo Experimental Forest, Puerto Rico, Patrick Gilkey

Master's Theses

Freshwater rock pools can serve as habitat for aquatic insects. Flash-flooding can have profound effects on insect communities in streams and rivers, but these effects have not been studied on freshwater rock pools. The goal of this thesis was to describe ecological patterns of the Sonadora River rock pool insect community at the Luquillo Experiment Forrest, Puerto Rico, specifically in response to intense flash-flooding, and then perform experiments to elucidate possible processes to explain those patterns. The rock pools contained primarily three taxa of Dipteran (true-fly) larvae, in order of decreasing abundance, 1) a newly discovered species of ceratopogonid (biting …

Efficacy Of Botanical Plant Extracts On The Population Dynamics Of Cotton Aphid, Aphis Gossypii Glover (Hemiptera; Aphididae), Habib Ali, Salma Ameer, Muhammad Qasim, Sajid Fiaz, Shahbaz Ali, Adnan Noor Shah, Saqlain Zaheer, Basharat Ali, Muhaamad Nawaz, Yasir Ali, Nazir Ahmad

Journal of Bioresource Management

Synthetic pesticides are excessively consumed to control crop pests but abundant use of chemicals may implicate the whole ecosystem badly in the end. Despite the growing concern, few natural products are commercialized for pest control whilst on-farm use of existing botanically-based pesticides remains a small, but growing, component of crop protection practice. The experiment was conducted to assess the potential trade-offs of using botanical extracts (Neem leaf extract, NLE, and Moringa leaf extract, MLE) along with synthetic insecticide, Confidor 200 SL, against Aphis gossypii Glover. Meanwhile, impact of these insecticides on natural enemies were also determined in the field experiment. …

Grassy–Herbaceous Land Moderates Regional Climate Effects On Honey Bee Colonies In The Northcentral Us, Gabriela M. Quinlan, Douglas Sponsler, Hannah R. Gaines-Day, Harper B G Mcminn-Sauder, Clint R V Otto, Autumn H. Smart, Théotime Colin, Claudio Gratton, Rufus Isaacs, Reed Johnson, Meghan O. Milbrath, Christina M. Grozinger

Department of Entomology: Faculty Publications

The lack of seasonally sustained floral resources (i.e. pollen and nectar) is considered a primary global threat to pollinator health. However, the ability to predict the abundance of flowering resources for pollinators based upon climate, weather, and land cover is difficult due to insufficient monitoring over adequate spatial and temporal scales. Here we use spatiotemporally distributed honey bee hive scales that continuously measure hive weights as a standardized method to assess nectar intake. We analyze late summer colony weight gain as the response variable in a random forest regression model to determine the importance of climate, weather, and land cover …
