“…The successful control of B. dorsalis therefore requires either mating disruption or a female attractant. Gravid females prefer to lay eggs in ripe mango fruits 7 – 10 , and 1-octen-3-ol was proposed as one of the olfactory cues that may guide this oviposition behavior 11 , 12 . We found that 1-octen-3-ol is more attractive to mated females than virgins, making it an ideal candidate for the development of a female attractant.…”

“…Examples include the fruit fly Drosophila melanogaster , which detects terpenes released by fermenting fruits 1 , 2 , the bean seed fly Delia platura , which detects 1-octen-3-ol and 3-octanone released by germinating seeds 3 , the silkworm moth Bombyx mori , which detects volatiles released by mulberry leaves 4 , and the parasitic wasp Anastatus japonicas , which detects β-caryophyllene, α-farnesene, and cis-3-hexen-ol released by host plants and insects 5 . The oriental fruit fly Bactrocera dorsalis (Hendel), one of the most destructive and invasive pests of fruit crops 6 , prefers to lay eggs on fully ripe mango fruit 7 – 10 . This is thought to reflect the attraction of gravid females to the volatiles.…”

The oriental fruit fly Bactrocera dorsalis (Hendel) is a notorious pest of fruit crops. Gravid females locate suitable oviposition sites by detecting host plant volatiles. Here, we demonstrate that 1-octen-3-ol, a volatile from mango, guides the oviposition behavior of female flies. Two odorant receptors (BdorOR7a-6 and BdorOR13a) are identified as key receptors for 1-octen-3-ol perception by qPCR analysis, heterologous expression in Xenopus laevis oocytes and HEK 293 cells followed by in vitro binding assays, as well as CRISPR/Cas9 genome editing in B. dorsalis. Molecular docking and site-directed mutagenesis are used to determine major binding sites for 1-octen-3-ol. Our results demonstrate the potential of 1-octen-3-ol to attract gravid females and molecular mechanism of its perception in B. dorsalis. BdorOR7a-6 and BdorOR13a can therefore be used as molecular targets for the development of female attractants. Furthermore, our site-directed mutagenesis data will facilitate the chemical engineering of 1-octen-3-ol to generate more efficient attractants.

Guava (Psidium guajava) encompasses a broad range of nutritional and therapeutic potential. Depending on the species, the fruits are 4-12 cm long and have a round or oval form. It belongs to the Myrtaceous family and mostly cultivated in tropical and subtropical climates of subcontinent including Pakistan, India and Bangladesh. The most therapeutic value could be traced in pink form of guava. The phytochemicals "quercetin, avicularin, apigenin, guaijaverin, kaempferol, hyperin, myricetin, gallic acid, catechin, epicatechin, chlorogenic acid, epigallocatechin gallate, and caffeic acid" have been investigated in the guava plant leaves for its therapeutic properties. Antidiarrheal, antihypertensive, antilipidemic, anticancer, and other health promoting benefits are associated in both of the fruits and the leaves of guava. The nutritional and phytochemical profiles of guava leaves are presented in detail in current review. Many bioactivities of guava leaf extracts are also critically investigated. Guava leaves might be employed as a component in of nutraceutical and medications due to their phytochemical profile. To prove the efficacy of the guava leaf extracts, further extensive clinical trials are needed.

“…While it is widely acknowledged that QFF host plants include apples, kiwifruit, and oranges, the chemical composition of the interaction between these fruits and the presence of QFF bacterial symbionts has been poorly investigated. Here, we showed that esters, terpenes, alcohol, and aromatics prevailed in the inoculated fruit MVOC pro les, similarly to non-inoculated fruits, such as guava, oranges, banana and mango commonly attractive to Tephritidae fruit ies (Malo et al 2005;Biasazin et al 2019;Jaleel et al 2021), and also shown to be attractive to QFF (Cunningham et al 2016;Mas et al 2020). We showed that the ester D-limonene, which was the second most abundant compound detected in EC-and KO-inoculated fruits, triggered a strong attraction of virgin female ies.…”

The Queensland fruit fly (Bactrocera tryoni) is a major polyphagous pest widespread in Australia and several Pacific Islands. Bacteria present on the host plant phyllosphere supply proteins, essential for egg development and female sexual maturity. We investigated the role of microbial volatile organic compounds (MVOCs) in attracting virgin females. Four Enterobacteriaceae commonly found on the host plant and in the gut of B. tryoni were cultured on different media (artificial and natural fruits), and their MVOCs were collected using two different headspace volatile absorbent materials (Tenax® filter and solid phase micro-extraction fibre; SPME), allowing to test for time and pH variations. The olfactory responses of virgin females to bacterial MVOCs were assessed via electrophysiology and behavioural assays. The production of MVOCs was strongly influenced qualitatively by the bacterial strain, the type of media and quantitatively varied with pH and time. Phenol was detected only from Citrobacter freundii (CF), while indole was found in all bacteria except CF. Indole production increased overtime in inoculated kiwifruits. D-limonene was detected from Enterobacter cloacae and Klebsiella oxytoca (KO) and associated with oranges and inoculated kiwifruit. Tenax extracts from KO invoked the strongest antennal response and attracted virgin females the most. Among the identified compounds triggering an olfactory response, D-limonene and 2-nonanone were both significantly behaviourally attractive whereas phenol, nonanal, isoamyl alcohol and some pyrazines appeared repulsive. This study provides a new foundation for developing a synthetic lure based on microbial volatiles to replace food baits targeting specifically virgin females.
