Inherited bacteria that parasitically distort the pattern of sex allocation their host, biasing towards female progeny, are found in many arthropods. One such manipulation is male-killing, where male progeny infected females die during embryogenesis. We here provide evidence for a male-killing bacterium coccinellid beetle, Adonia variegata . then address 3 questions. First, this one other hosts, or does it represent new transition to within eubacteria? Using sequence 16S rDNA bacterium, we...

Canlıların yavruyu meydana getirdiği yaş döneminin yavru bireyler üzerindeki etkilerinin doğru tespit edilmesi demografik çalışmalar için avantaj sağlamaktadır. Akdeniz meyve sineği, Ceratitis capitata gibi zararlı türlerle mücadelede popülasyon yaşının sonraki nesilde biyolojik parametrelere etkisinin bilinmesi yönetimi gereklidir. Bu çalışmada C. popülasyonunun tüm yaşamı boyunca ilk yumurtlama ve son süreleri baz alınarak eşit aralıklı 5 farklı grup oluşturulmuştur. Grupları oluşturan...

Abstract Background In this study, commercial bioinsecticides including entomopathogenic fungi, Beauveria bassiana , Metarhizium anisopliae and Verticillium lecanii Spinetoram active ingredient insecticide were evaluated against the tomato leaf miner, Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae) larvae. Main body The ingredients prepared at recommended concentrations under laboratory conditions applied to 2nd instar larvae of T. by spraying with a hand sprayer. On 1st, 3rd, 5th,...

Olfactory systems are indispensable for insects as they, including Western Flower Thrips (Frankliniella occidentalis), use olfactory cues ovipositing and feeding. F. occidentalis odorant binding proteins (OBPs) to transport semiochemicals receptors induce a behavioural response from the sensillum lymph of insect's antennae. This study identifies four OBPs analyses their expression at three stages growth: larvae, adult males females. Further, it investigates presence conserved motifs...

This study aimed to investigate the effects of local Beauveria bassiana (Balsamo) Vuillemin and Cordyceps fumosorosea (Wize) (Hypocreales: Cordycipitaceae) isolates on Ceratitis capitata (Wiedemann, 1824) (Diptera: Tephritidae) prepupae, during 2020 2021 in Mediterranean Region Türkiye. In petri dishes, mortality rates varied with doses: for LD.2016 (B. bassiana), between 30 60%, M6-4 30-46%, IFR (C. fumosorosea), 65-100%. Additionally, differences were detected prepupa pupa periods larvae...

The aim of the present study is to investigate effect three entomopathogenic fungi (EPF) (Beauveria bassiana, Cladosporium cladosporioides, and Verticillium alfalfae) on aphid species, Metopolophium dirhodum (Walker) (Hemiptera: Aphididae). selected EPF were isolated from agricultural soil National Institute Plant Protection (INPV) in Constantine, Algeria, tested against insects that collected same area. species M. exposed each fungal spore suspensions 107 conidia/ml for 10 s. Percent...

A survey was conducted in North Western Region (Bursa -Yalova cities) and central Anatolia (Ankara city) of Turkey, during 2009-2010 to evaluate the mite diversity population fluctuation on tomato plants.Thirty-four plant parasitic, predatory neutral species were identified belonging 14 families namely Tetranychidae, Eriophyidae, Tenuipalpidae, Bdellidae, Phytoseiidae, Stigmaeidae, Ascidae, Parasitidae, Ameroseiidae, Acaridae, Tydeidae, Iolinidae, Tarsonemidae Oribatidae.Among these species,...

Insect adipokinetic hormones (AKHs) are neuropeptides with a wide range of actions, including the control insect energy metabolism. These also known to be involved in defence system against toxins and pathogens. In this study, our aim was demonstrate whether application external AKHs significantly enhances efficacy entomopathogenic fungus Isaria fumosorosea model species (firebug Pyrrhocoris apterus) pest (Egyptian cotton leafworm Spodoptera littoralis pea aphid Acyrthosiphon pisum). It...

The Mediterranean fruit fly, Ceratitis capitata (Wiedemann) (Diptera: Tephritidae), is one of the mοst destructiνe pests in grοwings. It pupates soil. pupae are target οf many οrganisms sheltering sοil such as entοmοpathοgenic nematοdes (EPN). Pathοgenicity Turkish strain EPN, Steinernema feltiae, was eνaluated against late instar larνae, pupae, and adults C. under labοratοry conditions. Suspensiοns nematοde were applied at four increasing cοncentratiοns (0 (fοr cοntrοl) 50, 100, 200 IJs/ml)...

The spotted wing drosophila fly, Drosophila suzukii (Matsumura, 1931) (Diptera: Drosophilidae), is a pest which caused serious crop losses to soft-skinned fruits such as cherries, strawberries, and grapes. In this study, population dynamics of D. its associated parasitoids were investigated. surveys conducted at one location Uşak province, Turkey, between April December 2017 2018. For purpose, the baited traps weekly hung on fruit trees. Population in 2018 peaked end October mid-November,...

Abstract Background The Mediterranean fruit fly, Ceratitis capitata (Wiedemann) (Diptera: Tephritidae), is the major insect pest of production worldwide. Chemical control this has induced selection resistant medflies populations and negative environmental impact. In addition, use pesticides become an obstacle to fresh agricultural products exported many countries that restrict residues. aim study was propose alternatives based on microbiological for C. . Main body pathogenicity Turkish...

Abstract Overwintered pupae of fall webworm, Hyphantria cunea (Drury), were collected from 38 hazelnut ( Corylus avellana L. (Betulaceae)) plantations in Samsun province, Turkey, 2008 and 2009. Four chalcidoid (Hymenoptera: Chalcidoidea) species reared: Chouioia Yang (Eulophidae), Conomorium amplum (Walker), Dibrachys boarmiae Psychophagus omnivorus (Walker) (Pteromalidae). Overall parasitism was 11.97% 4.84% for 2009, respectively; richness on sites ranged one to three species. parasitised...

The study aimed to found out the potential efficacy of some bio-and synthetic insecticides used against Tuta absoluta (Lepidoptera: Gelechiidae) in tomato greenhouses.Chlorantraniliprole+abamectin, metaflumizone, azadirachtin, emamectin benzoate, spinosad, Bacillus thuringiensis and B. thuringiensis+azadirachtin mixture were applied by spraying method on leaf, which 5 third-stage larvae existed on.Distilled water was as a control compare with insecticides.Each applications performed six...
