The European corn borer, Ostrinia nubilalis (Hübner), is an important insect pest of corn, Zea mays L., crop in Moghan region. In field experiments, the density of eggs and larvae of O.nubilalis and percentage of eggs and larvae parasitisms were studied on four corn hybrids NS704 (commercial cultivar), NS770, NS640 and MV524 (cultivars with high yield). Furthermore, i...

Non-native insects and pathogens can alter the composition successional trajectories of forests and, in exceptional cases, drive their host trees functionally extinct. Emerald ash borer has killed millions its invaded range across eastern North America. Predicting future ecological role requires information on extent regeneration recruitment wake invasion. Variable levels have been observed sta...

20 A farmer's decision on whether to control a pest is usually based on the perceived 21 threat of the pest locally and the guidance of commercial advisors. Therefore farmers in a 22 region are often influenced by similar circumstances, and this can create a coordinated 23 response for pest control that is effective at a landscape scale. This coordinated response is 24 not intentional, but is a...

The present investigation entitled Evaluation of the efficacy some insecticides against rice yellow stem borer, Scirpophaga incertulas (Walker) was undertaken at MAE Farm, Regional Agriculture Research Station, Karjat (M.S.) during Kharif 2018. overall mean borer infestation (dead heart) varied from 1.23 – 7.50 per cent. T5 (Flubendiamide 20 WG @ 0.005%) recorded minimum (1.23%) and which signi...

Two common tree species, ash ( Fraxinus sp.) and oak Quercus sp.), could provide readily available media for denitrifying bioreactors that use wood-based carbon biological nitrate treatment. However, it is not known if the wood from Emerald Ash Borer-killed (EAB-killed) trees an effective source removal compared to other species or high-tannin nature of inhibits denitrification potential. This ...

Dirac is a hybrid motion-compensated codec that uses modern techniques such as wavelet transforms and arithmetic coding. It is an open technology which means that it is freely available and can be used without the payment of licence fees. Open technology is well suited to the business model of public service broadcasters as it allows open collaboration by those interested in its future developm...
