Oviposition Behavior Partitions Aquatic Landscapes Along Predation And Nutrient Gradients, C. A. Binckley, W. J. Resetarits Jr.

Biological Sciences Faculty Publications

That individuals attempt to minimize the ratio of mortality risk/growth rate (μ/g) when foraging within individual habitat patches is well established. Do species partition among spatially discrete communities embedded in complex landscapes in a similar manner? We investigated how 3 ovipositing species (2 Hyla treefrogs and a hydrophilid beetle, Tropisternus lateralis) responded to simultaneous gradients of nutrients and predation risk. Species partitioned our experimental metacommunity primarily by reducing oviposition with fish. Tropisternus positively responded to increased nutrients, but the effect decreased with increasing risk, as predicted by μ/g theory. Use of fish habitats by Tropisternus was unrelated to breeding …

The Long Term Effect Of Time-Memory On Forager Honey Bee (Apis Mellifera) Recruitment., Matthew Walter Otto

Electronic Theses and Dissertations

Experiments were performed to determine the influence of the honey bee time-memory on a forager bee's sensitivity to recruitment. Two groups of foragers from one colony were trained to separate food stations at the same restricted time of day for several consecutive days. Feeding then was canceled at one station but continued for four more days at the other. Bees with more days of training at a non-productive source were significantly less likely than foragers with less training to be recruited to an alternative food source presented at the same time of day. Furthermore, the ability of a forager to …

Investigation Of Matrilineal Relationships Via Mitochondrial Dna In The Southeastern Yellowjacket (Vespula Squamosa), Anthony Deets

Masters Theses

The question of whether and how apparently "altruistic" behaviors can evolve in social animals has received an enormous amount of attention from evolutionary biologists and has been termed "the central theoretical problem of sociobiology". Thus, recent interest is eusocial species with coexisting multiple queens stems from the realization that the genetic relatedness of individuals in such colonies presents additional theoretical challenges beyond those addressed by the Hamiltonian model of kin selection and lengthens the potential list of reproductive conflicts of interest.

The Southeastern Yellowjacket (Vespula squamosa) exhibits two social forms sympatrically in the southern parts of its range. These two …

Individual Variation In The Duration Of Territory Occupation By Males Of The Dragonfly Perithemis Tenera (Odonata: Libellulidae), Paul V. Switzer

Faculty Research & Creative Activity

In the dragonfly Perithemis tenera Say, males defend territories around oviposition sites and defense of a site is critical for reproductive success. This study first demonstrated that individual males varied consistently in how long they defended a particular territory within a day (their “tenure”) and in the quality of the sites they defended. I then investigated a number of factors that may have affected territory tenure and may have led to the observed variation among males. Territory occupations that ended “voluntarily” were significantly longer than those that ended because the male was evicted from his territory. For voluntary desertions, tenure …

Effects Of Fire Ants (Hymenoptera: Formicidae) On Hatching Turtles And Prevalence Of Fire Ants On Sea Turtle Nesting Beaches In Florida, Craig R. Allen, Elizabeth A. Forys, Kenneth G. Rice, Daniel P. Wojcik

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Red imported fire ants (Solenopsis invicta Buren) have increasingly been observed in loggerhead (Caretta caretta L.) and green (Chelonia mydas L.) sea turtle nests in Florida, and in the nests of freshwater turtles. They may be attracted to the disturbance, mucous and moisture associated with turtle nesting and establish foraging tunnels into turtle nests shortly after egg-laying, thus increasing the vulnerability of hatchlings to fire ant predation. We conducted experiments on a freshwater turtle (Pseudemys nelsoni Carr) to determine the potential impacts of S. invicta on turtle hatchlings. Over 70% of hatchlings were killed by …

Proximate Constraints On Intruder Detection In The Dragonfly Perithemis Tenera (Odonata: Libellulidae): Effects Of Angle Of Approach And Background, Paul Switzer, Perri Eason

Faculty Research & Creative Activity

The implications of insects’ vision for territorial defense have been relatively little studied in the field. In the dragonfly Perithemis tenera Say we investigated whether either the angle at which an intruder was viewed by a territorial resident or the background against which it was viewed affected the detection of that intruder. Residents detected intruders at a greater distance if the intruders were directly in front of them; they also detected more intruders in front of them than from other angles. Intruders viewed against distant vegetation were detected more readily than were intruders against near vegetation. Residents detected more intruders …

Salinity And Shade Preferences Result In Ovipositional Differences Between Sympatric Tiger Beetle Species, W. Wyatt Hoback, Douglas A. Golick, Tina Marie Svatos, Stephen M. Spomer, Leon G. Higley

Department of Entomology: Faculty Publications

1. Adult tiger beetles of the genus Cicindela often co-occur within a habitat but larvae do not. Larvae are sedentary and form usually permanent burrows at the site of oviposition where they require 1-3 years for development.

2. To test niche partitioning based on ovipositional preference, the behavior of two sympatric salt marsh tiger beetles, Cicindela circumpicta and C. togata (Coleoptera: Cicindelidae), were examined.

3. In laboratory studies, female C. circumpicta and C. togata distinguished between experimental salinities, with the former preferring 4 parts per thousand (ppt) and the latter preferring 12 ppt. In the field, C. circumpicta larvae were …

Factors Affecting Parental Investment Strategies In Male Waterbugs, Scott Kight

Masters Theses

Male giant waterbugs (Belostoma flumineum Say) brood eggs oviposited on their dorsi by conspecific females. Preliminary observations indicate that viable egg pads are sometimes discarded before hatching. Theory predicts that such behavior should occur only if costs incurred by brooding exceed benefits of hatching the egg pad. The amount of paternal investment per pad should be similar for both large and small pad sizes, but as egg pads become smaller, investment per egg increases. Thus, smaller pads should be more likely to be discarded unhatched than larger ones. Similarly, egg pads containing inviable eggs should also be more frequently …

Some Factors Affecting Male Mating Success In The Giant Waterbug (Belostoma Flumineum Say), Karyn S. Crisman

Masters Theses

Giant waterbugs (Subfamily Belostomatinae) are interesting in that males provide exclusive post-copulatory care of young. This unusual behavior makes this species an excellent study system for investigations of sexual selection theory because in such systems, sex role reversals are predicted. Previous studies indicate that role reversal in giant waterbugs is not complete because males still court females. It is assumed that from this courtship display females can assess male quality and "choose" a superior male. If some males are chosen over others then differential mating success results. This study was undertaken to ascertain some of the factors that affect male …

Mating Behavior Of The Giant Waterbug Belostoma Flumineum Say, Janet E. Ruppert

Masters Theses

Sexual selection theory predicts that in the few species where males make a larger parental investment than females and limit female reproduction, females should court and compete for males (i.e. we should observe "sex-role reversal"--Trivers, 1972). These predictions were tested in the laboratory with the giant waterbug Belostoma flumineum Say (Hemiptera: Belostomatidae) . Males of this species characteristically carry and brood eggs on their dorsa, thus making a substantial parental investment.

The courtship sequence in "one male:one female" pairings began with the male "pumping" (rapidly raising and lowering his abdomen at the water's surface). This presumably attracted the female, …

Sex Pheromone Activity In The Foveal Glands In The Two Species Of Ixodid Ticks: Dermacentor Andersoni (Stiles) And Dermacentor Variabilis (Say), Lynn Anne Collins

Biological Sciences Theses & Dissertations

Sex pheromone activity in the foveal glands of female Dermacentor andersoni (Stiles) and Dermacentor variabilis (Say) is described. Autoradiography revealed the accumulation of ³⁶Cl in the foveal glands of females during their first 120 hours of feeding on a ³⁶Cl-labeled host. Emissions collected from these females contained a ³⁶Cl-labeled product. This product, however, was absent in emissions collected from the same females with their foveae dorsales obstructed.

Accumulation of ³⁶Cl in the foveal gland, in conjunction with the release of a ³⁶Cl-labeled product through the foveae dorsales, suggest localization of sex pheromone activity within these …

Green Lemons Safe From Fruit Fly, A N. Sproul

Journal of the Department of Agriculture, Western Australia, Series 4

Importers' demands for fruit imports to be free of local pests places great restrictions on the movement of fruit between States, between countries, and sometimes within a State.

In Western Australia a Fresh Fruit Disinfestation Committee was formed in 1969 to direct State research aimed at developing techniques for post-harvest fruit sterilsation Programmes are supported by State and Federal funds and, in W.A., have provided staff and facilities to work on Mediterranean fruit fly. Parallel work with Queensland fruit fly and codlin moth is being done in New South Wales and Victoria.

The Ecology Of The Dominant Tick Species In The Northwestern Portion Of The Dismal Swamp National Wildlife Refuge, Mary Keith Garrett

Biological Sciences Theses & Dissertations

Elements of the ecology of the two dominant man-biting ticks were studied during 1971-1973 in two locations in Southeastern Virginia, namely, what is now the Dismal Swamp National Wildlife Refuge and Newport News City Park. Tick species composition, relative abundance, density, and distribution in the two areas were compared. In addition, the Dismal Swamp locality was used as a test area for studies on the survival of native, lab reared and translocated Dermacentor variabilis (Say) and Amblvomma americanum (L.) in relation to selected abiotic factors. The Newport News locality served as a control area for these studies.

Grain Aeration On The Farm, G D. Rimes

Journal of the Department of Agriculture, Western Australia, Series 4

ALTHOUGH grain aeration is a well known and widespread technique employed to prevent insect development in stored grain, the installations are invariably designed for large scale grain handling authorities.

Experimental work carried out in Western Australia over the last four storage seasons has shown that simple unsophisticated equipment can be of direct use in farm storage.

Webworm And The Weather, J A. Button

Journal of the Department of Agriculture, Western Australia, Series 4

FOR many years farmers have remarked on the cyclic occurrence of webworm outbreaks in their cereal crops.

Webworm, the State's most serious pest of cereals, has frequently assumed a role of major importance for one or two seasons, and then not been troublesome for a number of years.

A research programme being carried out by the Entomology Branch aims to give a better understanding of the effects of weather conditions on the seasonal incidence of webworm, and should lead to more effective control of this pest.

The House Fly (Musca Domestica), Clee Francis Howard Jenkins

Journal of the Department of Agriculture, Western Australia, Series 4

MANY insects are so commonly associated with man and his dwellings that they may almost be called domesticated.

In olden days the presence of these insects was accepted as a matter of course, but present knowledge shows that many of them can be important disease carriers while others may cause damage to food and clothing.
