Biological control is occasionally supplemented with insecticides treatments, which may have a significant impact on natural enemies. Typically, selective compounds are chosen to overcome lack of compatibility, but an alternative approach the use biocontrol agents resistant pesticides. Orius laevigatus (Fieber) (Hemiptera: Anthocoridae) main predator used thrips and other small pests in greenho...

Helicoverpa armigera (Hübner) is considered one of the most destructive insect pests chickpea crops in Morocco; however, extent yield loss it causes Morocco unknown. This study assessed losses and pod damage caused by borer H. on four improved Kabuli varieties with insecticide treatment at two different locations. The second part this investigated contact systemic toxicity biological selective ...

The effectiveness of the synthetic insecticides trichlorfon, lambda-cyhalothrin, cypermethrin emulsion concentrated (EC) and cypermethrin emulsion water based (EW) and a bio-insecticide, Bacillus thuringiensis subsp. kurstaki (Btk), was evaluated at 3, 7, 14 and 30 days after treatment (DAT) for the control of Metisa plana larvae in an oil palm (Elaeis guineensis) plantation in Malaysia. Althou...

this study assessed of youth involvement in agricultural production in sabon gari local government area. the data used for this study were collected using interview schedule administered to 112 respondents who were selected through multi-stage sampling procedure. descriptive statistics such as frequency, percentages and means were used to analyze the data. the result revealed that majority (95....

The extensive application of synthetic insecticides and herbicides over the past 50 years has led to a number problems, including negative effects on non-target organisms evolution pesticide-resistant pests. As an alternative means pest control, plant-based biopesticides have emerged. While developing new bioinsecticide, allelopathy both target pests crops must be evaluated. We evaluated volati...

Bacillus thuringiensis (Bt) being an eco-friendly bioinsecticide is effectively used in pest management strategies and, therefore, isolation and identification of new strains effective against a broad range of target pests is important. In the present study, new indigenous B. thuringiensis strains were isolated and investigated so that these could be used as an alternative and/or support the cu...

This paper explains an implementation model for a new method for Production Leveling designed for batch production system. The main structure of this model is grounded on three constructs: traditional framework for Operations Planning, Lean Manufacturing concepts for Production Leveling and case study guidelines. By combining the first and second construct, a framework for Production Leveling h...

Production leveling is an essential element of the Toyota Production System. It aims at balancing production volume as well as production mix to reduce waste, overburden, and unevenness. The application of conventional leveling approaches is limited by the requested product diversity. Because of this production leveling is predominantly used in high volume production. Nevertheless it can be imp...

In this paper we explore the production of streaming media that involves live and recorded content. To examine this, we report on how the production practices and process are conducted through an empirical study of the production of live television, involving the use of live and non-live media under highly time critical conditions. In explaining how this process is managed both as an individual...
