“…'Mahameru' is probably more preferred by adult leafhoppers due to its physical appearance with its taller stem and larger and lighter-colored leaves than 'Gepak Kuning'. Bullas-Appleton et al (2004) pointed out that the potato leafhopper (E. fabae) preference was significantly influenced by the leaf color of edible beans. Despite some reports suggesting an association between the density of foliar trichomes and the numbers of leafhopper adults and nymphs (Pillemer & Tingey 1978), our results showed that trichome densities of the varieties was not associated with their resistance levels against E. terminalis.…”

“…To find and identify their host plants, insects could use various sensory systems. A combination of visual (Bullas-Appleton et al, 2004;Fischer et al, 2004;Hausmann et al, 2004;Mäntylä et al, 2004), olfactory (Müller & Hilker, 2000;Kalberer et al, 2001;Zhang & Schlyter, 2004;Kalberer et al, 2005), and contact or gustatory cues (Jermy et al, 1988;Chapman & Sword, 1993;Mitchell, 1994;Schoonhoven et al, 1998) can finally lead the insect to its food source. However, all these cues vary in both their cost of assessment and accuracy, and some cues can be more reliable than others (Fawcett & Johnstone, 2003).…”

Olfactory versus Contact Cues in Host Plant Recognition of a Monophagous Chrysomelid Beetle

Abstract. The importance of olfactory versus contact cues for host plant recognition was investigated in the tortoise beetle Cassida canaliculata Laich. (Coleoptera: Chrysomelidae), which is strictly monophagous on meadow sage. The reaction of adult beetles to olfactory and contact host cues was tested using three bioassays (locomotion compensator, six-chamber-olfactometer, 'stem arena') to account for different behavioral contexts. Bioassay-guided fractionation of plant extracts was elaborated to characterize the nature of contact stimuli. The beetles were only slightly attracted to odors from small amounts of leaf material. However, when contact cues were provided additionally, the beetles showed strong preferences for samples of their host plant over controls. Bioassayguided fractionation led to isolation of at least two non-polar contact stimuli acting in concert that are sufficient for host plant identification in C. canaliculata.

“…Detection and processing of plant odours plays an important role in host plant detection by herbivorous arthropods (Moran and Brown, 1973;Todd et al, 1990;Bullas-Appleton et al, 2004;Bichao et al, 2005) and even in complex environments, an insect's central nervous system is capable of receiving information from volatiles that permits fine-scale spatio-temporal separation of odour sources (Bruce et al, 2005). Such odours vary substantially, depending on species, cultivar, growing conditions, age and plant parts (Takabayashi et al, 1994).…”

Problem statement: Evidence of rejection or acceptance by phytophagous pests of citrus plants treated with mineral oils suggests that impacts of oils may be related to detection by olfactory and/or contact chemoreceptors of repellent oils or plant volatiles. Alternatively, the oils may mask or suppress attractant host plant volatiles. To date, no studies have reported that oils elicit an olfactory response in Diaphorina citri Kuwayama [Hemiptera: Psyllidae]. Therefore, we undertook two studies to determine how oil deposits on citrus leaves influenced the behaviour of D. citri. Approach: The attractiveness of citrus leaves treated separately with an nC21 horticultural mineral oil and an nC24 agricultural mineral oil to D. citri was evaluated under laboratory conditions. In the first of two studies, the oils were applied as 0.5% aqueous emulsions to mandarin leaves and responses of adults determined after they walked on surfaces saturated with either distilled water or 2% aqueous emulsions of the oils. In the second study, responses of adult psyllids to host-leaf volatiles, mineral oil volatiles emanating from leaves dipped in 2% v/v aqueous emulsions of each oil and similarly treated filter paper paired with water-dipped leaves were determined in single, linear-tube olfactometers. Results: In the first study, deposits of both oils significantly reduced the proportion of D. citri attracted to citrus leaves. Prior exposure of the insects to oil deposits did not influence this response. However, prior contact with the HMO slightly reduced the proportion of psyllids alighting on the water-dipped leaves. In the second study, oil volatiles emanating from filter paper significantly reduced the attractiveness of water-dipped mandarin leaves. Conclusion: These results indicate that application of the oils to the mandarin leaves may have: (a) suppressed release of attractant host plant volatiles; (b) masked attractant host plant volatiles; (c) led to the release of repellent volatiles from leaves and/or (d) to adults being repelled by oil volatiles. The results from the study using the olfactometer suggested that detection of mineral oil volatiles by olfactory receptors of adult D. citri contributed to their response to oil deposits on the mandarin leaves.
