“…Simmonds (2001Simmonds ( , 2003 studied the bioactivity of different flavonoids and confirmed that these compounds could modulate the feeding and oviposition behavior of insects. Also, flavonoids inhibited the mycelial growth of a crop pathogen, Verticillium albo-atrum (Picman, 1995).…”

Cut-shoot bioassay test was used to study the significance of three flavonoids as aphicides against the woolly apple aphid (WAA), Eriosoma lanigerum (Hausmann). The used flavonoids were two flavanols that are quercetin dehydrate and rutin hydrate, but rutin hydrate is a glycoside of quercetin dehydrate. In addition to one flavanone that was naringine. These flavonoids were used at three concentrations; 100 ppm, 1000 ppm and 10,000 ppm. Results showed that the three tested flavonoids were active as aphicides against the target species and that mortality to nymphs was higher than that obtained against apterous adults. Increasing the concentration of the flavonoids resulted in a remarkable increase in nymphs mortality. However, rutin hydrate is more toxic to WAA than quercetin dehydrate and naringin.The three flavonoids had slight effect on the sole parasitoid of WAA, Aphelinus mali compared with effect caused by imodacloprid insecticide. Quercetin dehydrate, rutin hydrate and naringine can be used as botanical insecticides and incorporated into integrated management programs of the aphid.

“…Besides the numerous contributions to plant protection against biotic and abiotic stresses like UV radiation, microbial invasion, or herbivore activity (Harborne and Williams 2000;Simmonds 2003;Martens and Mithöfer 2005), Xavones can also act as signalling molecules, for example in the interaction of Xowers (copigmentation) and bees or between legumes and nitrogen-Wxing bacteria (Harborne and Williams 2000;Martens and Mithöfer 2005). Medical properties of Xavones include protective eVects against certain kinds of cancer and prevention of cardiovascular diseases (Arts and Hollman 2005;Martens and Mithöfer 2005), as well as eVects on the central nervous system (Wang et al 2005;Coleta et al 2006Coleta et al , 2008.…”

Five glucosyltransferases were cloned by RT-PCR ampliWcation using total RNA from Hieracium pilosella L. (Asteraceae) inXorescences as template. Expression was accomplished in Escherichia coli, and three of the HIS-tagged enzymes, UGT90A7, UGT95A1, and UGT72B11 were partially puriWed and functionally characterised as UDP-glucose:Xavonoid O-glucosyltransferases. Both UGT90A7 and UGT95A1 preferred luteolin as substrate, but possessed diVerent regiospeciWcity proWles. UGT95A1 established a new subgroup within the UGT family showing high regiospeciWcity towards the C-3Ј hydroxyl group of luteolin, while UGT90A7 primarily yielded the 4Ј-O-glucoside, but concomitantly catalysed also the formation of the 7-O-glucoside, which could account for this Xavones glucoside in H. pilosella Xower heads. Semi quantitative expression proWles revealed that UGT95A1 was expressed at all stages of inXorescence development as well as in leaf and stem tissue, whereas UGT90A7 transcript abundance was nearly limited to Xower tissue and started to develop with the pigmentation of closed buds. Other than these enzymes, UGT72B11 showed rather broad substrate acceptance, with highest activity towards Xavones and Xavonols which have not been reported from H. pilosella. As umbelliferone was also readily accepted, this enzyme could be involved in the glucosylation of coumarins and other metabolites.

SummaryWood extractives are one of the main reasons for the resistance of wood to termite attack. A study was carried out to determine the chemical constituents of wood extractives from Pinus roxburghii Sargent, Morus alba L. and Eucalyptus camaldulensis Dehnh against Coptotermes heimi (Wasmann) under laboratory conditions in Forman Christian College University (Lahor, Pakistan) in June 2015. Gas chromatography-mass spectrometry of wood extractives of P. roxburghii detected 1,2-benzenedicarboxylic acid, mono (2-ethylhexyl) ester and octadecanoic acid (methyl ester). Hexadecanoic acid (methyl ester) and 1-methyl-3-(1-methylethyl)-benzene were present in M. alba in addition to the compounds present in P. roxburghii and in E. camaldulensis 1,2-benzenedicarboxylic acid, mono (2-ethylhexyl) ester and β-phellandrene were also present. Based on the feeding activity, wood extracts were arranged in descending order of preference; P. roxburghii > M. alba > E. camaldulensis. Extracts of P. roxburghii, M. alba and E. camaldulensis proved repellent at higher concentrations, with tunneling activity almost fully inhibited. So these could prove useful in developing a soil barrier to block termite activity and serve as a replacement to synthetic chemicals. Keywords: Barrier, Eucalyptus camaldulensis, extractives, Morus alba, Pinus roxburghii, wood ÖzetOdun özütleri, termit saldırılarına karşı odun dayanıklılığının ana nedenlerinden birisidir. Bu çalışma 2015 yılı haziran ayında, Forman Christian College Üniversitesi (Lahor, Pakistan)'nde laboratuvar koşullarında Coptotermes heimi (Wasmann)'ye karşı Pinus roxburghii Sargent, Morus alba L. ve Eucalyptus camaldulensis Dehnh'in odun özütlerinin kimyasal bileşenlerini belirlemek amacıyla yürütülmüştür. P. roxburghi'nin odun özütlerinin gaz kromatografisi-kütle spektrometresi sonucunda, 1,2-benzendikarboksilik asit, mono (2-etilheksil) ester ve oktadekanoik asit (metil ester) tespit edilmiştir. M. alba'da P. roxburghii'de mevcut bileşiklere ilave olarak heksadekanoik asit (metil ester) ve 1-metil-3-(1-metil-etil)-benzen bulunurken, E. camaldulensis'te 1,2-benzendikarboksilik asit, mono (2-etilheksil) ester ve β-fellandren de bulunmuştur. Odun özütleri beslenme aktivitesi tercih sırasına göre, P. roxburghii > M. alba > E. camaldulensis şeklinde olmuştur. P. roxburghii, M. alba ve E. camaldulensis özütlerinin daha yüksek konsantrasyonlarda itici olduğu tespit edilmiş, tünel aktivitesi ise neredeyse tamamen engellenmiştir. Böylece, bu özütler termit aktivitesini engellemek için bir toprak bariyer geliştirilmesinde yararlı olabilir ve sentetik kimyasallara bir alternatif olarak hizmet edebilir.
