“…The hierarchy and combination of these different practices aim to limit the development of a wide range of pests. However, while some practices, such as fertilizer use (Garratt et al 2011) or habitat management (Landis et al 2000), are known to be efficient without any secondary detrimental effects on natural enemies, others, such as pesticide usage, are known to have detrimental effects (Theiling and Croft 1988). These combinations can result in differences in pesticide use intensity, i.e., frequency and toxicity, and are likely to exert differential pressures on pests and natural enemies.…”

Organic farming is mainly viewed as a homogeneous production system. Organic farming is also commonly thought to favor natural enemies of pests for crop protection. However, organic farming involves very different management practices and, in turn, various protection strategies. There is little knowledge on the influence of protection strategies on natural enemies in organic agriculture. Here, we analyzed crop protection strategies of 24 organic apple farmers in Southeast France. We also analyzed natural enemy communities in 12 apple orchards. We measured the impact of strategies on natural enemies using the International Organization for Biological and Integrated Control (IOBC) toxicity index. We identified four protection strategies: (1) the ecologically intensive strategy which promotes natural enemies by habitat management, (2) the substitution strategy mainly based on the use of pesticides, (3) the technologically intensive strategy which uses innovative technological methods such as exclusion nets and the integrated strategy which mobilizes a wide range of different practices. The IOBC toxicity index was 78.8±23.0 for the substitution strategy, 60.75±15.0 for the integrated strategy, 37.4±11.9 for the ecological strategy, and 31.25±1.7 for the technological strategy. We also found that the four strategies have different natural enemy communities such as the higher abundance of Forficula pubescens in the ecological strategy.

“…Concerning environmental attributes of pesticides, we differentiate between farmland biodiversity effects on the one hand, and levels of soil and groundwater contamination on the other hand. For farmland biodiversity, we concentrate on the loss of beneficial insects, which is an important biodiversity concern (Theiling and Croft, 1988;Perrings, 2010). Soil and groundwater contamination is a more general indicator of pesticide impacts on agroecosystems (Brethour and Weersink, 2001;Cuyno et al, 2001;Travisi and Nijkamp, 2008).…”

Abstract: Data from a farm survey and choice experiment are used to value the benefits of Bt cotton in Pakistan. Unlike previous research on the economic impacts of Bt, which mostly concentrated on financial benefits in terms of gross margins, we also quantify and monetize positive externalities associated with technology adoption. Due to lower chemical pesticide use on Bt cotton plots, there are significant health advantages in terms of reduced incidence of acute pesticide poisoning, and environmental advantages in terms of higher biodiversity and lower soil and groundwater contamination. These positive externalities are valued at US$ 79 per acre, of which half is attributable to health and the other half to environmental improvements. Adding average gross margin gains of US$ 204 results in an aggregate benefit of US$ 283 per acre of Bt, or US$ 1.7 billion for the total Bt cotton area in Pakistan.

Effects of 3 conventional insecticides (methyl parathion, azinphos-methyl, cypermethrin) and 3 insect growth regulators (fenoxycarb, diflubenzuron, and tebufenozide) on life-table parameters of Micromus tasmaniae Walker were determined in adults derived from insecticide-treated larvae. The following parameters were compared with the control: sex ratio, longevity, sterility, and fecundity. Power analysis was used to increase the efficiency and the predictability of the life-table test. Diflubenzuron resulted in a higher proportion female lacewings. Longevity was reduced for females emerging from fenoxycarb-and diflubenzurontreated larvae. Total number of eggs was reduced for diflubenzuron-and fenoxycarb-treated lacewings, as weIl as the following generation of tebufenozide-exposed lacewings. Daily number of eggs was reduced for the diflubenzuron treatment. Peak egg production was increased for lacewings exposed to azinphos-methyl and was decreased for the following generation of tebufenozide-exposed lacewings. Diflubenzuron treatment resulted in an extended preoviposition period. Oviposition periods were reduced for lacewings treated with fenoxycarb, diflubenzuron or azinphos-methyl as weIl as for the following generation of the tebufenozide treatment. The time to peak egg production was similar for all treatments. Methyl parathion, cypermethrin, and tebufenozide treatments showed no differences in any of the tested life-table parameters in the 1st generation. In summary, the insect growth regulators fenoxycarb and diflubenzuron had a more severe impact on life-table parameters than the 2 organophosphates and the pyrethroid. In future research, increased attention should be paid to long-term (e.g., the following generation) effects on life-table parameters.
