“…Risha et al (1990) reported that in most cases, immature stages were more susceptible than mature stages. Similarly, Don Pedro (1989) also observed that ovicidal and larvicidal action was more pronounced in Sitophilus zeamais Motsch when they were treated with vegetable oils (ground-nut, coconut, palm, sunflower and sesame).…”

Varying concentrations of powdered leaves of Eucalyptus and Mentha and rhizomes of Curcuma were evaluated in controlling Tyrophagus putrescentiae in wheat flour. At higher concentrations, all these plant materials significantly decreased the population build-up of the mite. Eucalyptus and Mentha leaf powders were effective at concentrations ranging from 100 to 5% in bringing about a decrease in the fecundity of the mite and reducing the egg numbers to 51.66 and 25.49 per female, respectively, as compared to 98.16 eggs per female in the controls. Rhizomes of Curcuma were effective even at a concentration of 0.1% reducing the egg laying to 7.66 eggs per female in wheat flour. These materials were more deleterious to immature stages (ova and larvae) than to the mature stages of T.putrescentiae. When tested on whole grains of wheat these plant materials showed more pronounced effects in controlling the mite population compared to that in wheat flour.Curcuma rhizomes were the most promising for possible use against T. putrescentiae.

“…Acorus rhizome possesses a wide range of pharmacological activities, such as sedative, central nervous system depressant, behavior modifying, anticonvulsant, memory enhancing, anti-inflammatory, antioxidant, antispasmodic, cardiovascular, hypolipidemic, and immunosuppressive (Mukherjee et al, 2007). Although the insecticidal activity of A. calamus against C. chinensis and other stored coleopterans has been reported previously (El-Nahal et al, 1989;Risha et al, 1990;Kim et al, 2003;Nandi et al, 2008), the investigation of field application of Acorus extracts in the management of stored insect pests is lacking.…”

Laboratory and field experiments were conducted to investigate the bioefficacy of sweet flag (Acorus calamus) against the pulse beetle Callosobruchus chinensis, which infests stored chick pea seeds. Dried powders of the leaf and rhizome as well as their extracts in methanol (ME) and petroleum ether (PEE) were evaluated as bio-insecticides against the beetle. Rhizome powder (5 mg/g seed) was found to be more efficacious, causing 100% mortality, than leaf powder (20 mg/g seed), showing 91.1% mortality. Rhizome powders also showed 100% ovicidal activity and thus completely inhibited F 1 emergence at a lower dose than that of leaf powders. The ME and PEE of leaves and rhizome showed 12 to 100% mortality. The percentage of egg laying decreased from 12.8 to 100 with increasing doses of powders and extracts. No F 1 adult emerged at 0.3-0.4 mg/g ME of leaves and rhizome and PEE of rhizome. In six-month field trials, all treatments at laboratory doses proved efficacious (75-98%) over organophosphate insecticide malathion (74.4%) in terms of feeding deterrence. Powder-and extract-treated chick pea seeds did not lose their viability and germinated at 100%, similar to control seeds. It was concluded that leaf and rhizome powders and their solvent extracts showed significant mortality, and inhibition of egg laying and F 1 emergence of C. chinensis at varying concentrations. Hence, the leaves and rhizome of A. calamus may be recommended as admixtures in the integrated management of beetle infestation of pulse seeds during storage.

“…Embriyonik gelişmenin ilerledikçe duyarlılığın daha fazla arttığını, 8. günde yumurtalarının açılmaya başladığı A. obtectus yumurtalarında, uçucu yağ buharının etkilediği zamanın yumurtanın bırakıldığı andan itibaren 4. günün (yumurta içerisinde embriyonun gözlenebildiği) kritik nokta olduğunu çünkü uçucu yağ ve monoterpenoid gibi bileşiklerin nörotoksin gibi işlev görebilmesi için hedef sinir sisteminin gelişmeye başladığında ancak ovicidal etkinin meydana gelebileceğini, ayrıca chorion ve vitellin zarının geçirgenliğinin embriyonun gelişmesi boyunca değiştiğinden dolayı ileri yaşlardaki yumurtalara uçucu yağ buharı difüzyonun kolaylaşacağını, fiziksel ve biyokimyasal süreçlerin daha fazla etkilenebileceğinin mümkün olabileceğini ifade etmişlerdir. Risha et al (1990) Acorus calamus bitkisinin rizomlarından elde ettikleri uçucu yağın depolanmış ürün zararlılarından Sitophilus granarius (Linnaeus, 1758), S. oryzae, Tribolium confusum Jacquelin du Val, 1863 ve Callosobruchus chinensis Linnaeus, 1758 türlerinin ergin öncesi dönemlerine karşı toksik etkilerini inceledikleri çalışmada en fazla duyarlılığa sahip olan türün C. chinensis yumurtalarında olduğunu bunu S. granarius ve S. oryzae'nın takip ettiğini fakat T. confusum yumurtalarını hiç etkilemediğini tüm durumlarda genç embriyonik dönemlerin ileriki dönemlerden daha duyarlı olduğunu larva ve pupa dönemlerinde fark edilebilir hiç bir duyarlılık olmadığını tespit etmişlerdir. Saraç & Tunç (1995) konsantrasyonlar ve maruz bırakma süreleri açısından değerlendirdiklerinde Ephestia kuehniella Zeller, 1879 yumurtalarının son dönem larvalardan daha az tolerans gösterdiğini, T. confusum yumurtalarının erginlerden daha fazla tolerans gösterdiğini tespit etmişlerdir.…”

SummaryThe cowpea beetle, Callosobruchus maculatus (Fabricius, 1775) (Coleoptera: Chrysomelidae) is a major pest of stored legumes seeds such as cowpea, chickpea, lentil, soybean, bean in both Turkey and many other countries. In this study, the fumigant effect of the essential oil obtained from rosemary [Rosmarinus officinalis L. (Lamiales: Lamiaceae)] plant was investigated against eggs, first and last-instar larvae and pupae of C. maculatus in chickpea. The study was conducted at Selcuk University, Faculty of Agriculture, Department of Plant Protection Entomology Laboratory under conditions at 28±2°C temperature, 55±5% relative humidity and fully dark conditions in 2013. As parallel to the increase of exposure time and applied dose, an increase occurred in mortality of immature stages of C. maculatus. First instar larvae and eggs were the most susceptible stages to rosemary oil while the pupae and last-instar larvae were the most tolerance stages. LC50 values for eggs, first and last instar larvae and pupae were found as 34.57, 27.64, 60.39 and 60.34 µl/l for 24 h exposure time of rosemary essential oil vapor, respectively. At 50 µl/l air dose of rosemary oil and exposure time of 24 h, mortality rates of eggs, first instar larvae, last instar larvae and pupae were determined 100, 91.33, 56 and 46%, respectively. In conclusion, rosemary essential oil showed high fumigant toxicity against the immature stages of C. maculatus. Key words:Rosmarinus officinalis, essential oil, fumigant toxicity, Callosobruchus maculatus, immature stages Özet Türkiye'de ve birçok ülkede Börülce tohum böceği, Callosobruchus maculatus (Fabricius, 1775) (Coleoptera: Chrysomelidae) börülce, nohut, mercimek, soya fasulyesi, kuru fasulye gibi depolanan baklagil tohumlarında önemli bir zararlıdır. Bu çalışmada, nohutta Börülce tohum böceğinin yumurtalarına, dane içerisindeki ilk ve son dönem larvalarına ve pupalarına karşı biberiye [Rosmarinus officinalis L. (Lamiales: Lamiaceae)] uçucu yağının fumigant toksisitesi araştırılmıştır. Çalışma, 2013 yılında Selçuk Üniversitesi Ziraat Fakültesi Bitki Koruma Bölümü Entomoloji Laboratuvarında 28±2⁰C sıcaklık, %55±5 orantılı nem ve tamamen karanlık ortamda yürütülmüştür. Doz ve maruz bırakma süresinin artışına paralel olarak C. maculatus'un ergin öncesi dönemlerinin ölüm oranlarının arttığı belirlenmiştir. Ergin öncesi dönemler içerisinde en hassas dönemlerin yumurta ve birinci larva dönemi olurken, en dayanıklı dönemlerin ise pupa ve son dönem larvaların olduğu tespit edilmiştir. 24 saat süreyle biberiye uçucu yağının gaz haline maruz bırakılan yumurtaların, birinci dönem larvaların, son dönem larvaların ve pupaların LC50 değerleri sırasıyla 34.57, 27.64, 60.39 ve 60.34 µl/l hava olarak belirlenmiştir. Biberiye uçucu yağın 50 µl/l hava konsantrasyonuna24 saat süreyle maruz bırakılan yumurta, birinci dönem larva, son dönem larva ve pupalarda sırasıyla, %100, 91, 56 ve 46'ya varan ölüm oranları tespit edilmiştir. Sonuç olarak biberiye uçucu yağının C. maculatus'un ergin öncesi dönemlerine karşı yüks...
