“…Cydia pomonella (Knight and Light 2001) exhibit positive anemotaxis even in the absence of odorous stimuli, but upwind distance increases 40% in the presence of a-farnesene. Anemotaxis may also have been a factor in studies of Elasmopalpus lignosellus (Huang and Mack 2002), and Diabrotica virgifera virgifera (Bernklau and Bjostad 1998a,b), wherein larvae preferentially selected passages carrying odorized airflow over passages with odorless flows. Anemotaxis has only been explicitly disproved in one species: Psila rosae walk upwind in an odor plume, but if the odor is removed or the gradient rendered uniform, the upwind orientation disappears (Jones and Coaker 1977).…”

“…Orientation of larval stages toward hostplant or prey odors have been shown in Lepidoptera, (Elasmopalpus lignosella, Huang and Mack 2002;Epiphyas postvittana, Suckling and Ioriatti 1996;Helicoverpa armigera Singh and Mullick 2002;Rembold et al 1989; Spodoptera littoralis, Khalifa et al 1973), Coleoptera (Cassida denticollis, Müller and Hilker 2000;Leptinotarsa decemlineata, Chin 1950;Dickens 2002; Cassida denticollis, Coccinella septempunctata, Stubbs 1980; Ctenicera destructor, Doane et al 1975; Diabrotica virgifera virgifera, Bernklau and Bjostad 1998a,b;Hippodamia convergens, Jamal and Brown 2001;Orthosoma brunneum, Paim and Beckel 1963) and Diptera (Drosophila melanogaster, Oppliger et al 2000; Delia antiqua, Mochizuki et al 1989; Psila rosae, Coaker 1977, 1979). Other behaviors including arrest and changes in speed or straightness of travel have also been observed, in addition to or in the absence of orientation behavior (Hughes et al 2003;Hunter 1978;Stubbs 1980;Jamal and Brown 2001;Bradley and Suckling 1995;Jones and Coaker 1977).…”

Using a servosphere (locomotion compensator), locomotory behavior of Colorado potato beetle Leptinotarsa decemlineata Say (Coleoptera: Chrysomelidae) larvae was measured in detail in response to pulsed and non-pulsed odors of hostplant and conspecific pheromone. Second instars showed decreased straightness of movement, and all larvae showed decreased speed, in response to potato odor. Change in straightness by 2nd instars was also significantly affected by the interaction of pheromone and pulsing treatments. Fourth instars showed increased positive anemotaxis in response to the combined hostplant and pheromone odors. To our knowledge, this is the first demonstration of larval behavioral responses to adult pheromone in a holometabolous insect.

“…Electrophysiological studies confirm that some of these neurons detect plant odors, on the antenna (Dethier and Schoonhoven 1969;Dethier 1980) and on the maxillary palps (Roessingh et al 2007). Despite this limited sensory equipment, neonate larvae of several Lepidoptera species are able to orient towards odors released from their host plants and to express specific choices (Huang and Mack 2002;Singh and Mullick 2002;Castrejon et al 2006), presumably by recognizing patterns of combined odors and contact chemicals (Dethier 1976).…”

Pulsed Odors from Maize or Spinach Elicit Orientation in European Corn Borer Neonate Larvae

Lepidoptera larvae are capable of orienting towards or away from plants by using odors as cues but whether this attraction is innate or secondarily acquired remains unknown. We tested the hypothesis that European corn borer (ECB) neonate larvae express an innate attraction towards odors released from maize, and avoidance towards odors from spinach. Neonate larvae were placed on a locomotion compensator within a constant stream of humidified air that was loaded intermittently with airborne odors drawn from potted plants. The odor stream was delivered continuously or pulsed (1 to 10 sec pulses) at 40 ml/min. ECB larvae oriented toward maize odors pulsed at 2 to 6 sec but walked away from maize odors delivered at lower frequencies (9 and 10 sec pulses or to continuous ones). They consistently walked away from spinach odors, irrespective of the pulsing regime except at 1 sec pulses that did not elicit orientation. We further explored odor intensity on orientation towards maize odors by adjusting the odor stream intensity. At higher intensity (60 ml/min), the direction reversal started at the 6 sec half period, while at lower intensity (20 ml/min), it showed up only for the continuous stimulus. ECB larvae exhibit a striking ability to lock on to a direction, which they maintained despite gaps of up to 10 sec in the odor stream. Our results demonstrate that ECB neonate larvae express innate orientation preferences towards natural odors from plants. These reactions correlate well with the biological value of these plants for ECB: maize generally is accepted by ECB larvae and adults, while spinach represents a poor host because it produces (non-volatile) phytoecdysteroids that are toxic and deterrent.

“…Despite their small size and rudimentary olfactory system, phytophagous caterpillars are capable of discriminating complex odors. Numerous examples show that they can actively orient toward volatiles from their host plant (Carroll and Berenbaum, 2002;Huang and Mack, 2002;Singh and Mullick, 2002;Castrejon et al, 2006;Becher and Guerin, 2009), toward plants attacked by conspecifics larvae (Carroll et al, 2006(Carroll et al, , 2008Mooney et al, 2009), or selectively move away from odors of non-host plants (Piesik et al, 2009), and even detect conspecific adult female pheromone (Poivet et al, 2012). Several species can learn the odor of their host plant on which they feed (Saxena and Schoonhoven, 1982;Carlsson et al, 1999;Rojas and Wyatt, 1999), and perform associative learning with tastants (Salloum et al, 2011), with noxious stimuli associated with feeding on a noxious host plant (Dethier, 1980a) or with an electric shock (Blackiston et al, 2008).…”

In Lepidoptera, the behavior of caterpillars to plant odors is poorly known. However, caterpillars are equipped with a reduced number of olfactory sensilla (3 on the antenna and 4-5 on the maxillary palps) which they can use to make fine discrimination between complex plant odors. In this work, we characterized behavioral responses of Spodoptera littoralis larvae to 11 odorants found in plants using binary choices in a Petri dish assay. In this assay, 1-hexanol, hexanal and cis-jasmone elicited a dose-dependent attraction, camphene and eugenol were repellent, while the response to other odorants were less marked. We recorded the electrophysiological responses to 5 of these odors from olfactory neurons of sensillum B2 of the antenna. Several neurons from this sensillum responded to each of the chemicals tested by an increase of their firing activity on top of a high background activity, suggesting that olfactory neurons of caterpillars is broadly tuned to a range of odorants rather than being specialized to a few molecules.
