“…The melon fly prefers cucurbits as their host plants. Their attraction towards several cucurbit fruits namely cucumber, bitter melon, ivy gourd, zucchini, cantaloupe and kabocha has been previously investigated (Miller et al, 2004;Piñero et al, 2006Piñero et al, , 2021. Melon flies were attracted to freshly sliced cucumber under field condition (Prokopy et al, 2003(Prokopy et al, , 2004, and this observation led to the identification of several compounds from cucumber that are attractive to female melon flies (Siderhurst & Jang, 2010).…”

“…Inopportunely, these lures lack potency, have restricted field life, are arduous to handle and attract non‐target species (Jang & Light, 1996). Presently, there are limited studies on female attractants of melon flies (Jang et al., 2017; Piñero et al., 2021; Shelly et al., 2017; Siderhurst & Jang, 2010) and there is a need for prospecting other host volatiles for alternative and possibly, better attractants.…”

Globally, cucurbit crops constitute over 5.6% of the total vegetable production (Rai et al., 2008). Several insect pests are known to disrupt the production of cucurbits; among them, the melon fly, Zeugodacus cucurbitae (Coquillett) (Diptera: Tephritidae), is a key pest causing considerable economic loss (Badii et al., 2015;Ekesi et al., 2011). Losses are mainly through fruit-damage by ovipositing female flies, thus decreasing overall yield (Ordax et al., 2015).Presently, control of melon flies is mainly through use of insecticides (Aktar et al., 2009;Dhillon et al., 2005). Although the use of male para-pheromone traps (Cuelure) has proven to be effective in controlling fly population levels, populations can easily recuperate with few males that escape trapping. Therefore, control of female population is desirable as they are the primary reason for damage and future fly populations. There are few lures that attract females and are limited to phago-attractants such as protein hydrolysate and sugars (Jang & Light, 1996). Inopportunely, these lures lack potency, have restricted field life, are arduous to handle and attract non-target species (Jang & Light, 1996). Presently, there are limited

“…An age effect was also found in female melon flies, Zeugodacus cucurbitae , in attraction to volatiles emitted by preferred host plants with an increase in attraction during their lifetime, with the strongest attraction occurring when they reached sexual maturity at approximately four weeks of age. Less preferred hosts, however, did not vary in their attractivity as a function of female age [ 81 ].…”

Chemical communication is very important in herbivorous insects, with many species being important agricultural pests. They often use olfactory cues to find their host plants at a distance and evaluate their suitability upon contact with non-volatile cues. Responses to such cues are modulated through interactions between various stimuli of biotic and abiotic origin. In addition, the response to the same stimulus can vary as a function of, for example, previous experience, age, mating state, sex, and morph. Here we summarize recent advances in the understanding of plant localization and recognition in herbivorous insects with a focus on the interplay between long- and short-range signals in a complex environment. We then describe recent findings illustrating different types of plasticity in insect plant choice behavior and the underlying neuronal mechanisms at different levels of the chemosensory pathway. In the context of strong efforts to replace synthetic insecticides with alternative pest control methods, understanding combined effects between long- and close-range chemical cues in herbivore–plant interactions and their complex environment in host choice are crucial to develop effective plant protection methods. Furthermore, plasticity of behavioral and neuronal responses to chemical cues needs to be taken into account to develop effective sustainable pest insect control through behavioral manipulation.

“…To explore alternative control methods, it is crucial to understand the molecular mechanisms underlying fly behaviour. Female B. cucurbitae use host-plant volatiles as cues to locate suitable hosts ( Vargas et al, 2018 ; Piñero et al, 2020 ; Jaime et al, 2021 ). Although the role of these volatiles in host-seeking behaviour has been documented, the molecular basis of chemoreception in B. cucurbitae remains poorly understood.…”

The melon fly, Bactrocera cucurbitae (Coquillett) (Tephritidae: Diptera), is an invasive pest that poses a significant threat to agriculture in Africa and other regions. Flies are known to use their olfactory systems to recognise environmental chemical cues. However, the molecular components of the chemosensory system of B. cucurbitae are poorly characterised. To address this knowledge gap, we have used next-generation sequencing to analyse the antenna transcriptomes of sexually immature B. cucurbitae adults. The results have identified 160 potential chemosensory genes, including 35 odourant-binding proteins (OBPs), one chemosensory protein (CSP), three sensory neuron membrane proteins (SNMPs), 70 odourant receptors (ORs), 30 ionotropic receptors (IRs), and 21 gustatory receptors (GRs). Quantitative real-time polymerase chain reaction quantitative polymerase chain reaction was used to validate the results by assessing the expression profiles of 25 ORs and 15 OBPs. Notably, high expression levels for BcucOBP5/9/10/18/21/23/26 were observed in both the female and male antennae. Furthermore, BcucOROrco/6/7/9/13/15/25/27/28/42/62 exhibited biased expression in the male antennae, whereas BcucOR55 showed biased expression in the female antennae. This comprehensive investigation provides valuable insights into insect olfaction at the molecular level and will, thus, help to facilitate the development of enhanced pest management strategies in the future.
