“…Octenol is used as an aggregation pheromone in the sawtoothed grain beetle, Oryzaephilus surinamensis 42 and as a plant attractant in the black blowfly, Phormia regina 43, the legume pod borer, Maruca vitrata 44, the Grapevine Moth, Lobesia botrana 45, the European grape berry moths, Eupoecilia ambiguella 46 and the sandfly Lutzomyia longipalpis 47. It is also used as a compost attractant for the phorid fly, Megaselia halterata 48 and as an avoidance cue for the parasitoid Lariophagus distinguendus 49.…”

Olfaction is a key insect adaptation to a wide range of habitats. In the last thirty years, the detection of octenol by blood-feeding insects has been primarily understood in the context of animal host-seeking. The recent discovery of a conserved octenol receptor gene in the strictly nectar-feeding elephant mosquito Toxorhynchites amboinensis (TaOr8) suggests a different biological role. Here, we show that TaOR8 is a functional ortholog of its counterparts in blood-feeding mosquitoes displaying selectivity towards the (R)-enantiomer of octenol and susceptibility to the insect repellent DEET. These findings suggest that while the function of OR8 has been maintained throughout mosquito evolution, the context in which this receptor is operating has diverged in blood and nectar-feeding mosquitoes.

“…The more difference in the chemical profiles of an herbivore host and its plant background, the more olfactory contrast generated, and the more detectable a host larva becomes (Hilker & McNeil, ). Similar observations have been reported for male moths (Light et al ., ; Deng et al ., ; Yang et al ., ; von Arx et al ., ) and parasitoids (Xu et al ., ) in which plant volatiles synergistically enhanced the detection of female sex pheromones. The relevance of plant volatiles as background odors in parasitoid host location has been discussed in previous studies (Mumm & Hilker, ; Schröder & Hilker, ; Beyaert et al ., ).…”

The role of herbivore‐ and plant‐related experiences in intraspecific host preference of a relatively specialized parasitoid

Parasitoids use odor cues from infested plants and herbivore hosts to locate their hosts. Specialist parasitoids of generalist herbivores are predicted to rely more on herbivore-derived cues than plant-derived cues. Microplitis croceipes (Cresson) (Hymenoptera: Braconidae) is a relatively specialized larval endoparasitoid of Heliothis virescens (F.) (Lepidoptera: Noctuidae), which is a generalist herbivore on several crops including cotton and soybean. Using M. croceipes/H. virescens as a model system, we tested the following predictions about specialist parasitoids of generalist herbivores: (i) naive parasitoids will show innate responses to herbivore-emitted kairomones, regardless of host plant identity and (ii) herbivore-related experience will have a greater influence on intraspecific oviposition preference than plant-related experience. Inexperienced (naive) female M. croceipes did not discriminate between cotton-fed and soybean-fed H. virescens in oviposition choice tests, supporting our first prediction. Oviposition experience alone with either host group influenced subsequent oviposition preference while experience with infested plants alone did not elicit preference in M. croceipes, supporting our second prediction. Furthermore, associative learning of oviposition with host-damaged plants facilitated host location. Interestingly, naive parasitoids attacked more soybean-fed than cotton-fed host larvae in two-choice tests when a background of host-infested cotton odor was supplied, and vice versa. This suggests that plant volatiles may have created an olfactory contrast effect. We discussed ecological significance of the results and concluded that both plant- and herbivore-related experiences play important role in parasitoid host foraging.

“…Leaf acetate attracted male Grapholita molesta (Busck) in laboratory experiments (Varela et al., ) and increased the trapping efficiency of G. molesta sex pheromones in field experiments (Yu et al., ,b). Thus, leaf acetate was used as a potentiator for the sex pheromones of G. molesta (Yu et al., ,b) and also enhanced the attractive effect of Lobesia botrana (Denis & Schiffermüller) sex pheromones on males (Von Arx et al., , ). Our results indicated that unmated PFM males have higher EAG values than females to the optimum dose of leaf acetate.…”

Previous studies have revealed that α‐farnesene plays a crucial role in female detection and location of host plants (Landolt et al., ; Binder et al., ; Bengtsson et al., ; Witzgall et al., ), whereas leaf acetate plays a crucial role in female courtship and mating with males (Von Arx et al., , ; Yu et al., ,b).

The peach fruit moth (PFM), Carposina sasakii Matsumura (Lepidoptera: Carposinidae), a severe pest of Ziziphus jujuba Miller fruit trees (jujube, Rhamnaceae) mainly grown in China, has increasingly hindered the development of the jujube industry in recent years. In order to provide a theoretical basis for a physical obstruction method, we evaluated the effect of three commonly sold physical barriers on PFM host‐searching behavior. Two principal volatiles generated by the jujube tree, α‐farnesene and cis‐3‐hexenyl acetate (leaf acetate), were used as references to detect electroantennography (EAG) response values of 2‐, 4‐, and 6‐day‐old PFM adults. The results indicated different EAG responses toward α‐farnesene and leaf acetate between different ages of PFM, and males responded differently than females. The EAG responses were stronger in 4‐day‐old males to leaf acetate and in 2‐day‐old females to α‐farnesene. The two‐choice behavioral Y‐tube olfactometer assay confirmed that PFM was strongly attracted to α‐farnesene and leaf acetate. We determined the EAG and behavioral responses of PFM after spraying three kinds of physical barriers: Liquid Film Fruit Bag, High Lipid Film, and Jujube Protection No. 1. We obtained strong inhibitory effects on PFM attraction to both volatile lures using these barriers, including negative taxis by both females and males to Liquid Film Fruit Bag and Jujube Protection No. 1. We can infer that Liquid Film Fruit Bag is the most promising potential physical barrier for PFM control, with Jujube Protection No. 1 ranking as second‐best.
