Pesticide resistance of Tetranychus cinnabarinus[[taliem.ir]

Pesticide resistance of Tetranychus cinnabarinus (Acari: Tetranychidae) in China: a review

This paper reviews the development of pesticide resistance in Tetranychus cinnabarinus (Boisduval) and studies on the genetics and management of pesticide resistance in China. This mite has developed resistance to at least 25 pesticides in China. It first developed resistance to parathion and demeton. As early as 1962, the level of resistance to demeton in T. cinnabarinus reached 62 times, which resulted in control failure of this mite on cotton in most cotton growing areas in China. The genetics of omethoate-resistance and monocrotophos-resistance in T. cinnabarinus is each controlled by an incompletely dominant gene and the development of resistance is therefore rapid. The developmental time and other life table parameters of T. cinnabarinus are altered when the mite becomes pesticide-resistant: life cycle becomes shorter and reproductive rate becomes greater. This is another reason for the rapid development of pesticide resistance in T. cinnabarinus. Pesticide resistance may be managed by rotational use of pesticides, biological control and other methods.
Evaluating management training[taliem.ir]

Evaluating management training and development in a cross-cultural context A stakeholder approach

Purpose – The purpose of this paper is to address the challenge in evaluating China’s overseas management training and development (MTD) in cross-cultural settings. It examines the evaluation practice of China’s overseas MTD interventions and explores a comprehensive approach to the MTD evaluation. Design/methodology/approach – This study collected both quantitative and qualitative data from 526 major stakeholders involved in China’s overseas MTD. A mix method approach is used to explore the perspectives of different stakeholders. Findings – The respondents from different stakeholder groups perceived purposes of evaluation and problems conducting evaluation differently. The perceived evaluation criteria and approaches by individual group were also focused differently. The current evaluation system was based on segmented information collection and little joint effort was found in the MTD evaluation. The judgement on the value of China’s overseas MTD is culturally sensitive due to the diversity of stakeholders from different cultural backgrounds. A new framework is proposed to address the evaluation challenge. Research limitations/implications – This study is limited to evaluating China’s MTD between China and the UK. The valuation framework is based on complex involvement of multiple stakeholders in an international setting. It may not be applicable to situations where only two parties are involved in training. Practical implications – The proposed stakeholder-based evaluation framework may be used for other skill-based training and development programs involving multiple stakeholders in the international arena. Originality/value – This paper contributes to the HRM evaluation literature by focusing on a unique evaluation setting and proposes a framework to evaluate a complex international MTD initiative by the Chinese Government.
