This flexibility of parasitoids to rapidly link diverse chemicals to resource needs and subsequently report them with recognizable behaviors offers new insights into their foraging adaptability, and provides a model for further dissection of olfactory learning related processes. Historically, we have marveled at the capacity of organisms to sense chemical cues and learn to utilize them for foraging and other forms of biotic interactions von Frisch, , ; Muller-Schwarze and Silverman, ; Menzel, ; Vet et al.
We have been able to harness the chemical detection ability in dogs for use in, for example, search and rescue, and detection of a multitude of illegal chemical substances. Despite the abundant information on olfaction and odor learning in organisms, the mechanisms or processes involved in the use of odor cues in biotic interactions are poorly understood Alkasab et al.
Parasitoid species may provide good models for olfaction studies, because of their extraordinary capacity to utilize odors and learning to increase foraging success [reviews in Vet et al. Microplitis croceipes , a relatively specialized parasitoid of three highly polyphagous larval hosts, Heliocoverpa zea, Heliothis virescens and Heliothis subflexa Lepidoptera: Noctidae can detect their hosts through associative learning of hosts, host byproducts and host plant-related chemicals Lewis and Tumlinson, ; Turlings et al.
This wasp species has also demonstrated the ability to learn and subsequently fly to the novel odors chocolate and vanilla, and these parasitoids can learn these odors in association with both food and hosts and subsequently respond in accordance to their physiological state Takasu and Lewis, However, encounters with plant-related compounds, such as those associated with chocolate and vanilla, are expected within the scope of typical foraging activities. To further explore the range of odors that female M.
These compounds were cyclohexanone a cyclic ketone , 3-octanone an aliphatic ketone , octanal an aliphatic aldehyde , diisopropyl aminoethanol an aliphatic alcohol , and 2,4- and 3,4-dinitrotoluene DNT aromatic hydrocarbons with methyl and nitrogen side chains. These compounds were presented with adult food as the unconditioned stimulus in flight bioassays.
Behavioral responses to cyclohexanone for food-associated odor conditioned Manduca sexta Daly et al. In addition to oriented flight, chemical cues also mediate a sequential array of parasitoid foraging behaviors, including hovering, landing, antennation and ovipositor probing Lewis et al.
As the wasps get closer to the resource, their behavior is progressively more intense, distinctly characteristic and specific to the respective resource Lewis et al. Larvae of Heliocoverpa zea Boddie Lepidoptera: Noctuidae were reared on pinto bean artificial diet Burton, Microplitis croceipes were reared on H.
All M. Food conditioned females were fed for 5—10 s three times, with 30 s intervals between feeding Takasu and Lewis, For conditioning, odors were delivered to females while they were feeding or antennating feces. A structurally diverse group of compounds with very different volatilities was chosen to probe the limits of the wasps' behavioral responses. For this reason a variety of formulation methods were required to deliver the different odors to the wasps at constant rates.
No attempt was made to determine the limits of responses to any of the compounds or to compare responses to equal quantities of different compounds by the wasps since this was beyond the objectives of this study. Cyclohexanone and diisopropyl aminoethanol, which are highly volatile, were formulated in capillaries 0.
Both 2,4- and 3,4-DNT, which have low volatility, were dispensed from filter paper, and 3-octanone and octanal were dispensed from membrane formulations Heath et al. The release rate of each compound from its respective formulation was measured by collecting the volatized compound on a Super Q Alltech, Deerfield, IL filter trap and analyzing by capillary GC-MS Heath et al.
Wasps fed while the odor was blown over their antennae. Control females fed while air was blown over their antennae. Control females were conditioned with sucrose and water only. The flight tunnel was previously described Drost et al.
Females were placed on a stand 13 cm high , 80 cm downwind of the chemical source s. Females were tested to membranes Heath et al. For test and control females, the number of landings on the target or alternate source was recorded. Females that did not complete a flight after three chances or that did not take flight after 5 min were scored as no response.
A total of 8—10 females per control and odor-conditioned treatments were assayed per day over 2- 4days. The influence of conditioned odor on the response of trained and control females were tested with chi-square analyses SAS Institute, We developed separate training protocols for the close-range food-associated and host-associated behaviors. Instead of intense local search and substrate antennation, we trained the odor-conditioned wasp to enter a recessed hole from which the conditioned odor emanates Figure 1A.
A 4 mm 2 filter paper saturated with sucrose and water was placed on top and center of the aluminum foil and 9—10 holes 1 mm diam. Test females were released near a recessed hole 2 mm diam in the center of a hollowed out Teflon stand external: 2 cm diam. This stand was set directly on top of the compound-loaded filter paper. Females responded positively by entering the hole at least half of their body length within the hole within 10 s.
Females antennated larval feces near 2,4-DNT or 3-octanone loaded on filter paper as for food conditioning. A piece of filter paper 0. The paper was gently and continuously waved in front of the wasps while maintaining a distance of 0. Females responded positively by coiling within 10—30 s. Females responded negatively by showing no coiling response within 1 min. For each odor, 3-octanone and 2,4-DNT, a total of 40 food and odor-conditioned females, 40 host and odor-conditioned females, 40 food-only conditioned females control , and 40 host-only conditioned females control were tested for seek and coil behavioral responses.
Positive and negative seeking and coiling behaviors were recorded for each female. Em junho incorporou-se ao programa o humorista Juan Carlos Librado "Nene". Anna Simon voltou a apresentar 2 semanas. A partir de abril de , uniu-se ao elenco do programa como colaboradora frequente.
