Hybridization and Use Of Grapes as an Oviposition Substrate Improves the Adaptation of Olive Fly Bactrocera oleae (Rossi) (Diptera: Tephritidae) to Artificial Rearing Conditions

International Journal of Industrial Entomology (2014)

The olive fly Bactrocera oleae (Rossi) is the key pest for olive cultivation worldwide. Substantial effort has been invested in the development of the sterile insect technique (SIT) to control this pest. One of the limitations to develop SIT technology for olive fruit fly is the low ability of wild females to lay eggs in other medium than olive fruits, and their slow adaptation to oviposition in artificial substrates. In the present study, fruit grapes were used as an alternative egg collection medium to harvest eggs and young larvae from freshly colonized wild strains originating from France, Italy, Spain and Croatia. The larvae were allowed to develop into the fruits until the second instar, before they were extracted out and further reared on a standard artificial diet. Furthermore, F1 to F4 female flies were alternatively offered wax bottles to oviposit. Finally, the performance of hybrid strains created from crosses between wild and long colonised flies was assessed. The results showed that females of all 4 wild strains readily oviposited eggs in grapes and from the F2 generation onward, females from all strains were adapted to laying eggs in wax bottles. No difference was observed in eggs and pupae production among all strains tested. The findings are discussed for their implications on SIT application against olive fruit fly.

One for all: Mating compatibility among various populations of olive fruit fly (Diptera: Tephritidae) for application of the sterile insect technique

PLoS ONE (2018)

The olive fruit fly, Bactrocera oleae (Rossi), is the most important insect pest for the cultivation of olives worldwide. Considerable research efforts have been invested in the past decades to develop eradication or suppression tactics for use within an area-wide integrated pest management (AW-IPM) approach that includes a sterile insect technique (SIT) component. One of the major obstacles encountered in the development of SIT for olive fruit fly was the inferior quality of the mass-reared flies, expressed among others evident primarily by sterile males having a different timing of peak mating and a lower mating propensity in comparison with their wild counterparts. In this study we assessed the mating behaviour and mating compatibility of olive fruit flies originating from four countries of the Mediterranean region (Croatia, France, Italy, Spain) in walk-in field cages and post zygotic compatibility (expressed as % egg hatch) under laboratory conditions. Furthermore, we tested the hypothesis whether a hybrid strain (Greece (domesticated)/Israel (wild)) adapted to laboratory rearing conditions showed any mating barriers with all the four "wild" populations. Finally, we examined the effect of colonization on the mating compatibility of the four newly established populations over three consecutive generations. The results showed no pre-zygotic (mating barriers) or post-zygotic isolations (measured by egg hatch%) among the olive fruit fly populations from the four countries tested. Also, there was no evidence of mating barriers between the hybrid strain and the wild populations of the Mediterranean region.

A consistent CO₂ assimilation rate and an enhanced root development drives the tolerance mechanism in Ziziphus jujuba under soil water deficit

Arid Land Research and Management (2020)

Muḥammad Ṣābir Fahad Rasheed Zikria Zafar İmran Khan Muhammad Nawaz

Shifting toward stress-resistant planting material has become a pre-requisite for fruit tree culture under arid to the semiarid environment. No information currently exists on the physiological basis of water stress tolerance in Ziziphus jujuba at the saplings stage, an important fruit tree of semiarid regions of Central Punjab. Therefore, an experiment was conducted under controlled conditions where plants were subjected to three watering regimes: control irrigation, a medium, and a high-water deficit treatment. During the experiment, growth, biomass production and allocation in different plant organs (leaves, stem, and root) were measured. The physiological response of Z. jujuba under water deficit was determined through a gas exchange system and CO2 assimilation rate, stomatal conductance, and water use efficiency were evidenced. Biomass production/allocation in leaves and stem decreased significantly with an increase in soil water deficit. Root biomass production remained unchanged (p = 0.907), but allocation increased significantly under high soil water deficit (p < 0.001). Net CO2 assimilation rate (A) remained similar at 6.54 ± 0.32 μmol m−2 s−1 but, stomatal conductance (gs) decreased significantly from 94.0 to 69.2 mmol m−2 s−1 under high water deficit treatment. Water use efficiency (ratio between Net CO2 assimilation rate and transpiration rate) also increased significantly (p = 0.012) under high water deficit treatment. Ziziphus jujuba showed a medium degree of plasticity under water deficit conditions, which was mainly driven by a sustained CO2 assimilation rate and more biomass allocation for root development.

Green synthesis of silver nanoparticles from grape and tomato juices and evaluation of biological activities

IET Nanobiotechnology (2016)

Muhammad Zia Shadab Gul Javeed Akhtar Ihsan ul Haq Bilal Haider Abbasi

The biosynthesis of silver nanoparticles (AgNPs) is substantial for its application in lots of fields. Tomato and grape fruit juices were used as a reducing and capping agents for the biosynthesis of AgNPs. Ultraviolet spectroscopic analysis offered peaks in the range of 396‒420 nm that indicate the production of AgNPs. Fourier transform infrared spectroscopy analysis revealed attachment of different functional groups with Ag ion in both tomato and grape fruit extracts NPs. The X‒ray diffraction analysis confirmed that the synthesised AgNPs have a face centred cubic confirmation. Scanning electron microscopy confirms the size of NPs that varies from 10 to 30 nm. The DPPH free radical scavenging assay, total antioxidant capacity, reducing power assay, total flavonoid contents and total phenolic contents determination confirmed that synthesised AgNPs are potent antioxidant agents; can be used as an effective scavenger of free radicals. Biosynthesised AgNPs also showed good antibacterial activity against Pseudomonas septica, Staphylococcus aureus, Micrococcus luteus, Enterobacter aerogenes, Bacillus subtilis and Salmonella typhi. Protein kinase inhibition activity showed a clear zone which indicates anticancerous potential of biosynthesised AgNPs. The efficacious bioactivities indicate that the tomato and grape derived AgNPs can be used efficiently in pharmaceutical and medical industries.

Age‐dependent effect of methyl eugenol on male mating success of the peach fruit fly, Bactrocera zonata

Entomologia Experimentalis et Applicata (2023)

Awais Rasool Muhammad Farooq Hussain Munis Said Hussain Shah Sehar Fatima Afshan Irshad

Abstract The peach fruit fly, Bactrocera zonata (Saunders) (Diptera: Tephritidae), is a pest of economic importance, endemic to South and South‐East Asia. It is highly invasive and due to its quarantine pest status, it interferes with horticultural trade. Males of many Bactrocera species are strongly attracted to methyl eugenol (ME) [1,2‐dimethoxy‐4‐(2‐propenyl) benzene], a phenylpropanoid compound naturally occurring in many plant species. Feeding on ME is also reported to enhance male mating success in several Bactrocera species. Such an effect can increase the effectiveness of the sterile insect technique (SIT). The current study was designed to identify the sexual maturity age of males of B. zonata , the relation between male age and attraction to ME, and the effect of ME on male mating success. The results showed that males initiated their mating at 8 days of age and attained the highest mating success at 16 days of age. The percentage of immature males responding to ME increased with age and the maximum response was observed during the age of sexual maturity. Methyl eugenol treatment at sexual maturity significantly enhanced male mating success over untreated males. The males treated with ME at a sexually immature age (5 days old) achieved significantly higher mating success after reaching sexual maturity. These findings suggested that B. zonata males can be treated with ME at the age of 5 days in sterile‐male ‘holding and release’ facilities and thereafter released in the field, where they are expected to achieve higher mating success after attaining sexual maturity. The results are discussed as a valid approach for enhancing the effectiveness of SIT application against B. zonata .

Implication of OPRM1 A118G Polymorphism in Opioids Addicts in Pakistan: In vitro and In silico Analysis

Journal of Molecular Neuroscience (2018)

Madiha Ahmed Ihsan ul Haq Muhammad Faisal Durdana Waseem Malik Mumtaz Taqi

Single nucleotide polymorphism in OPRM1 gene is associated with hedonic and reinforcing consequences of opioids. Risk and protective alleles may vary in different populations. One hundred healthy controls and 100 opioids (predominantly heroin) addicts from Pakistani origin were genotyped for A118G (N40D) polymorphism in OPRM1. Structural and functional impact of the polymorphism on encoded protein was predicted by in silico analysis. Results show significant association between homozygous GG genotype and opioid addiction in Pakistani population (p value = 0.016). In silico analysis by SIFT (TI = 0.61), PolyPhen (PISC = 0.227), PANTHER (subPSEC = -1.7171), and SNP effect predicted this SNP benign for encoded protein. Superimposing wild-type and mutated proteins by MODELLER shows no change (RMSD = 0.1) in extracellular ligand binding domain of μ-opioid receptor. However, Haploreg and RegulomeDB predicted OPRM1 gene repression by chromatin condensation and increased binding affinity of RXRA transcription factor that may reduce protein translation and hence the number of available receptors to bind with drugs, which may trigger underlying mechanisms for opioids addiction. Thus, this study outlines causal relationship between opioids addiction and genetic predisposition in Pakistani population.
