Behavior in Insect Mimicry
نویسنده
چکیده
Arthropods use insect mimicry to gain predatory advantages over other insects in the form of increased resource availability and protection from predators. They do this through several different mechanisms, 4 of which are described in the paper; Batesian, Peckhamian, Wasmannian, and Tephritid mimicry. ‘Mimicry’ includes resemblances in both appearance and behavior. Without mimicry in both appearance and behavior (given both are displayed by the model) the organism will be unsuccessful in mimicking its selected model. This was shown through Greene and Mather’s research on tephritid flies and salticid spiders. Appearance and behavior must be conspicuous to be detected by the deceived. Photuris fireflys and Portia spiders use aggressive mimcry to lure their prey near to them. Then they capture their prey and enjoy the meal. This type of mimicry is not as common as Batesian mimicry but a very interesting strategy nonetheless. Ants are especially formidable prey. Their defenses are strong and relentless, which keeps them safe from common ant predators (birds, other arthropods, etc.). A successful mimic of an ant would enjoy the same protection from predators. Several different spider families have evolved to do just that. 1. Mimicry, as described in this paper, is developed over the course of thousands of years through the mechanism of natural selection. It is not a choice made by the organism.

P105: Inhibition of Vasculogenic Mimicry in a Three-Dimensional Culture in Glioblastoma
Glioblastoma is one of the most common primary brain tumors (80% of patients) that has a poor prognosis due to malignancy. Glioblastoma has an annual incidence of 5.26 per 100 000 population or 17 000 new diagnoses per year and so as the population aging, the number of patients is expected to increase. There is a growing body of literature investigating the tumor microenvironmenta...

We propose that the many different, but essentially similar, eye-like and face-like color patterns displayed by hundreds of species of tropical caterpillars and pupae-26 examples of which are displayed here from the dry, cloud, and rain forests of Area de Conservacion Guanacaste (ACG) in northwestern Costa Rica-constitute a huge and pervasive mimicry complex that is evolutionarily generated and...
متن کاملAmino Acid Change in an Orchid Desaturase Enables Mimicry of the Pollinator’s Sex Pheromone
Mimicry illustrates the power of selection to produce phenotypic convergence in biology [1]. A striking example is the imitation of female insects by plants that are pollinated by sexual deception of males of the same insect species [2-4]. This involves mimicry of visual, tactile, and chemical signals of females [2-7], especially their sex pheromones [8-11]. The Mediterranean orchid Ophrys exal...
متن کاملInsect mimicry of plants dates back to the Permian
In response to predation pressure, some insects have developed spectacular plant mimicry strategies (homomorphy), involving important changes in their morphology. The fossil record of plant mimicry provides clues to the importance of predation pressure in the deep past. Surprisingly, to date, the oldest confirmed records of insect leaf mimicry are Mesozoic. Here we document a crucial step in th...
