JIS: Tschinkel 2.12.2002   (Site not responding. Last check: 2007-10-10) This behavior results in the attraction of mates and receptivity to males that attempt to mate by clasping and holding the female's genitalia with their own (Callahan 1958). The calling and mating behavior of newly emerged, virus-infected, female moths was examined during the first scotophase to determine if virus replication resulting in the malformation of reproductive tissues and the presence of a "virus" plug present over the reproductive opening affected the mating behavior of these insects. Behavioral responses of the gypsy moth in a wind tunnel to air-borne enantiomers of disparlure. www.insectscience.org /5.6   (3976 words)

CHAPTER TWENTY Our discussion of insect reproduction seemed to assume female insects were sort of automatically endowed with sperm at the correct times in their lives. The business of locating mates, courtship interactions, mating, fertilization, depositing eggs, and caring for and provisioning offspring (or not doing these activities) are aspects of mating systems. Insect also elaborate a number of biochemical and physiological mechanisms to enhance an individual's chances of assuring paternity. entomology.unl.edu /ent801/mating.html   (2855 words)

Insect Behavior and Biocontrol Research Unit : About Us The mission of the Insect Behavior and Biocontrol Research Unit is to characterize, describe, and analyze the behavior and behavioral genetics of pest and beneficial insects, and to develop tactics for managing lepidopterous insects, fruit flies, and other pests utilizing semio chemical /acoustic based technology, natural enemies, and autocidal strains derived from molecular manipulations. Identification of behavioral traits of pest and beneficial insects that may be amenable to biological, cultural and/or genetic manipulation Adult courtship and mating behaviors of the invasive cactus moth were described, and field cage tests found the Sterile Insect Technique to be a potentially efficacious tactic for control www.ars.usda.gov /AboutUs/AboutUs.htm?modecode=66-15-10-10   (484 words)

Aquatic Insects of the Sonoran Desert The types and morphological traits of aquatic insects present are closely related to the type of stream habitat, as well as to the kinds of food energy that are available. Insects that occupy the stream during their larval stage and then leave to reproduce as terrestrial adults, including mayflies, stoneflies, caddisflies, moths, dragonflies and damselflies, and the Diptera or true flies, spend almost their entire lives in the juvenile aquatic stage. The toe-biter is one of the only insects here to produce eggs more than once; if one batch fails due to flooding or desiccation, she returns to the water to lay another batch when conditions permit. www.desertmuseum.org /books/nhsd_aquatic_insects.php   (3705 words)

Florida Entomologist, v. 81, n. 3, p. 351 Mating behavior of Rhynchophorus cruentatus (Fabricius) was investigated in the laboratory. Mating was defined as the attempted insertion of the aedeagus of one male weevil while in contact with another female or male weevil. Overall, the frequency of mating per session was consistent with that of the weevils in arenas with vacant treatment chambers in experiments 3 and 6, suggesting that volatiles emanating from below may influence mating behaviors. www.fcla.edu /FlaEnt/fe81p351.html   (4116 words)

ARS | Publication request: Evidence of the Importance of Juvenile Hormone for Flight in Solenopsis Invicta Female ... Behaviors associated with a nuptial flight were examined in untreated female alates to determine whether one or a combination of behaviors contributes to post-mating dealation. Pre- copulatory behaviors investigated were 1) excited alates scurrying on the surface of the soil, 2) excited alates climbing onto vegetation, 3) tethered alates flying for 5min but not primed for a nuptial flight, and 4) alates displaying all of the described pre-mating behaviors. Mating, alone or in combination with other behaviors and/or environmental cues, may be a major factor inducing dealation. ars.usda.gov /research/publications/publications.htm?SEQ_NO_115=122307   (285 words)

Drapean2 The Copulatron, a multi-chamber apparatus for observing Drosophila courtship behaviors. In addition, courtship and mating behaviors are difficult to study because by definition they involve studying the interaction between two sets of behaviors – those of males and those of females. Next to each 1” mating chamber, a ¼ inch-diameter “antechamber” was drilled such that its edge slightly overlapped that of the main 1” chamber. www.ou.edu /journals/dis/DIS83/Technique83/10tecDrapeau/Drapeau.htm   (882 words)

Let's Talk About Insects They can create a new kind of insect or ask that they all make insects they are familiar with like a firefly, cicada, lady bug or praying mantis. Insects rarely seen during the day can be observed at night by setting up a simple light trap.

Duke University Department of Molecular Genetics & Microbiology Whereas two gender and their intimate interactions contribute to the survival of a species, recognizing and appropriately interpreting the complex external world and reacting to it with well-measured responses and behaviors is crucial for the survival of each individual. In insects including Drosophila, a large part of the external world is represented in the form of hundreds, if not thousands, of distinct fragrances and odors recognized by sophisticated olfactory organs. Our major interest in the study of sex-specific processes is focused on male courtship behavior, an innate behavior that is displayed by a male towards a female prior to copulation. mgm.duke.edu /faculty/amrein   (705 words)

Part 1: Section 2: Love Molecules: Pheromone’s Effects on Behavior However, when the anesthetized male hamster was rubbed with vaginal secretions from the female hamster, the normal hamster instead of rejecting it tried to mate with the anesthetized male. Eventually, the protein, which triggered such a clear-cut response, was isolated and termed “Aphrodisin.” This substance was found to be a carrier protein for a smaller molecule, which is bound to the air borne pheromone. However, if they waited to remove the organ after the hamsters had some experience with females, the male’s mating behavior was normal. serendip.brynmawr.edu /bb/berman/P1S2.htm   (861 words)

Ecology: Coming of Age with Elephants: A Memoir. - book reviews She is completely honest about the rigors of field research in Africa, not only about living in tents, but also about being a female in a society that does not respect women a great deal. Students often ask what can kind of career they can obtain with their biology degree; here is an account of someone that has a strong background in biology and, with that knowledge, became active in the political arena of elephant conservation. The book starts in the spring, explaining mating behaviors, and ends in the winter, when most insects are in diapause. www.findarticles.com /p/articles/mi_m2120/is_n2_v78/ai_19409345   (741 words)

Do Species Exist in Nature? They can be divided by "pre-zygotic"[1] mechanisms, which include geographical, temporal, and habitat separations, as well as behavioral or physical isolating mechanisms. A habitat separation can be as small as one species of insect living in pears and another in apples, but as long as they don't come into contact with each other, they can't mate. Behavioral isolating mechanisms include things like mating dances and other courtship rituals which must be completed properly before mating will occur. tiger_spot.mapache.org /Biology/species.html   (1742 words)

Endocrine System In insects, the largest and most obvious endocrine glands are found in the prothorax, just behind the head. The neurosecretory cells are found in clusters, both medially and laterally in the insect's brain.   Insect physiologists suspect that brain hormone is bound to a larger carrier protein while it is inside the neurosecretory cell, and some believe that each cluster of cells may produce as many as three different brain hormones (or hormone-carrier combinations). www.cals.ncsu.edu /course/ent425/tutorial/endocrine.html   (732 words)

ITEC Courses in Animal Behavior The ideas, methods, and practical knowledge acquired in the first half will be used and synthesized in the second half of the course in which each student designs and carries out his or her own research project. Due to the presence of both marine and terrestrial habitats at the Bocas del Toro Biological Station, the number of potential behavioral subjects is immense, and ranges from mammals, amphibians, reptiles, birds, and insects and other arthropods in terrestrial ecosystems to fishes, turtles, dolphins, mollusks, echinoderms, and crustaceans in marine ecosystems.

Entomology - Ring T. Cardé   (Site not responding. Last check: 2007-10-10) Insects employ a variety of chemical cues to find and identify resources. Most of our research is aimed at understanding the theoretical basis of these odor-mediated behaviors, including chemistry of the odors and how wind disperses them, and the orientation maneuvers that flying insects use to locate odor sources. Other studies examine the patterns of mating behaviors, the genetic architecture of variation in pheromone production and response, and simulation modeling of pheromone diffusion and insect response. www.entomology.ucr.edu /people/carde.html   (784 words)

paf Once a female comes in sight, the male tries to lead her to his selected leaf where, if she is agreeable, mating takes place and she lays her eggs. The males are slightly smaller than the females, but you would have to see a male and female side-by-side to be able to tell. Only the males have the vocal sacs and there are one or two slits at the back of the throat where air is forced into the sac. www.thewildones.org /Animals/paf.html   (418 words)

Lounge   (Site not responding. Last check: 2007-10-10) It appears in the moving sculpture of clouds and river sand, in the songs of birds and insects, the play of sunlight thru a forest canopy, and in the cleansing calm that follows a storm; it also appears in the ravages of disease, compost and rot, predation and combat, and catastrophic habitat change. In this way we see a larger culture of Nature at work as the planet evolves thru the ages and turns thru the seasons, in the fragrance of a spring breeze, the progression of a summer thunderstorm, the ripening fruits and grains of autumn, and the frozen quiet of a moonlit winter night. Acknowledgment of the fertility circuit provides a pervasive ethic for human behavior, a “law of appreciation”, which is a foundation of nature-based spirituality. www.tribesofcreation.com /newsite/pages/lounge.html   (8873 words)

|| DukeMedNews || Fruit Fly Pheromone Receptor First Ever Discovered Linked to Specific Sexual Behavior Like mammals, insects display complex mating behaviors, many of which are triggered automatically in response to pheromones or other stimuli, Amrein said. Courtship in Drosophila includes a regular sequence of behaviors, which are critical for mating, Amrein explained. Although an earlier study found that mice lacking 16 genes thought to include pheromone receptors exhibited abnormal sexual and aggressive behavior, this is the first study to clearly link a single pheromone receptor to a specific mating behavior, Amrein said. www.dukemednews.org /news/article.php?id=7022   (810 words)

Tufts E-News -- Kindling The Romance Frequently during the summer's firefly season, Lewis and her students spend nights hunched in the grass, observing the mating insects and capturing some for study. The light that fireflies give off is the insect equivalent of winking, luring prospective mates with a pattern of flashes, looking for a match. Different species have different flashing behaviors, but the occasional instance of varying flash behaviors within one species – and varying female responses to those flashes – has drawn scientists' attention. www.tufts.edu /communications/stories/061405KindlingTheRomance.htm   (375 words)

Dartmouth Medical School - DMS Genetics Study Unlocks Insects' Secret for Love in the Dark   (Site not responding. Last check: 2007-10-10) The researchers bred male fruit flies missing the ppk25 gene and placed them in a chamber with female flies in either the light or the dark to test their response to pheromones. In the light, the mutant males engaged in normal mating behaviors, but by using an infrared camera to monitor their behavior in the dark, the researchers found that the mutant males failed to engage in any mating behavior. The research team, that includes co-authors Heping Lin, Kevin Mann, Elena Starostina, and Ronald Kinser from the DMS department of Genetics, will now set their sights on determining whether ppk25 functions in the neurons that respond to pheromones or in parts of the brain where that signal is processed. dms.dartmouth.edu /news/2005_h2/29aug2005_insects.shtml   (520 words)

Scientific American: 15 Answers to Creationist Nonsense In practice, this standard can be difficult to apply to organisms isolated by distance or terrain or to plants (and, of course, fossils do not breed). Biologists therefore usually use organisms' physical and behavioral traits as clues to their species membership. In most of these experiments, researchers subjected organisms to various types of selection--for anatomical differences, mating behaviors, habitat preferences and other traits--and found that they had created populations of organisms that did not breed with outsiders. www.sciam.com /print_version.cfm?articleID=000D4FEC-7D5B-1D07-8E49809EC588EEDF   (4167 words)
