The insecticide treatment against C. napi was applied two weeks earlier than the usual treatment against B. aeneus and C. pallidactylus. Insecticide treatment is necessary at high pest abundance soon after the pest's appearance, and then once or twice within 7-8 day interval. Thank you. Less damage is caused by rape winter stem weevil Ceutorhynchus can be achieved using economic thresholds, crop monitoring and computer-based decision support systems. can cause significant yield losses to oilseed rape (Brassica napus L.), and chemical control is often needed to protect crops from these pests. CAB ABSTRACTS Graham, C.W., Gould, H.J. Cabbage stem weevil (Ceuthorrhynchus quadridens) It has 1-3 generations a year and winters as an adult in the superficial layer of the soil and under the vegetable debris on the soil. The efficacy of six insecticides, chlorpyriphos + cypermethrin, bifenthrin, alpha-cypermethrin, pirimiphos-methyl, thiacloprid and tau-fluvalinate, was tested in a four year field trial. in winter oilseed rape (Brassica napus L.), Analysis of oilseed rape stem weevils chemical control using damage rating scale, Forecasting the breaching of the control threshold for Ceutorhynchus pallidactylus in oilseed rape, Incidence of pyrethroid-resistant oilseed rape pests in Germany, Current status of resistance in pollen beetle (Meligethes aeneus F.) to selected active substances of insecticides in Poland, Phenology of British butterflies and climate change, The Major Insect Pests of Oilseed Rape in Europe and Their Management: An Overview. diversity of the agroecosystem incorporating hedgerows, cover crops, flowering conservation headlands and field margins to in winter oilseed rape (Brassica napus L.) - Volume 150 Issue 2 - J. CNKI We forecast the abundance of the cabbage stem weevil at levels above the control threshold in oilseed rape in springtime. Additionally, the time span of possible migration is prolonged for about 30 days under projected future climate conditions. One important reason for this is the occurrence of insect pests, including the cabbage stem flea beetle, the rape stem weevil, the cabbage stem weevil, the pollen beetle, the cabbage seedpod weevil, and the brassica pod midge. It now occurs throughout most of the temperate region of the United States. cauliflower, kohlrabi, etc. The past decade has seen considerable If mean winter temperatures between 5 and 13 February are closer to 4.0 °C than to −2.4 °C, no breaching of the control threshold is to be expected in the subsequent March. are being developed that use host plant preferences and behavioural responses to semiochemicals to influence pest and natural New findings regarding the phenology of stem weevils show that both species were sporadically present in our experimental oilseed rape fields as early as during autumn (from the end of October 2010, BBCH 17-18). This is usually between 20% pod set and the end of flowering.

Although currently brassica pest control is performed according to the appearance of first specimens of Ceutorhynchus or other brassica pests, for a large number of insecticide treatments a positive biological efficiency is observed (however, within a large range – 8–98%). DOAJ (Directory of Open Access Journals), Control of cabbage stem weevil and pollen beetle with one insecticide application | Marek Seidenglanz, Jaroslav Šafář, Nikoleta Rubil, Miriama Ruseňáková, Veronika Roskóová | Agricultural Journals Sprays of gamma‐HCH or azinphos‐methyl + demeton‐S‐methyl sulphone which were effective against stem weevil could also in some years give improved control of blossom beetles (Meligethes spp.) Based on the statistical relationship between the mean winter air temperature and the abundance of the cabbage stem weevil in the winter oilseed rape, risk maps were derived as a forecast tool for practical farming. crop husbandry practices as well as, on the landscape scale, through habitat and environmental manipulation to encourage vegetational Based on multi-site and multi-annual observations of the cabbage stem weevil [Ceutorhynchus pallidactylus (Marsham, 1802)] in winter oilseed rape (Brassica napus Linnaeus) and the corresponding meteorological measurements, a statistical relationship for forecasting the abundance was derived. The larvae are up to 8 mm long and 0.5 mm wide. The present approach can be easily transferred to regions where air temperature data are available, although it should not be used without prior local validation.

Contrary to this, an almost significant dissociation between cumulative distributions of C. pallidactylus males and B. aeneus adults was recorded in 2014. necessary. After about 3 weeks of feeding the females begin to lay eggs in the pods and this continues until the seeds are formed. Resistance of pollen beetles (Brassicogethes aeneus) to insecticides complicates control of cabbage stem weevils (Ceutorhynchus pallidactylus) in winter oilseed rape crops. for: Cabbage stem flea beetle, rape stem weevil, pollen beetle, cabbage stem weevil, cabbage seed weevil, brassica pod midge • proPlant DSS developed in Germany, used widely in Europe • Based on phenological models of pest immigration and life cycle development parameters • Uses local weather conditions (temperature, sunshine h, All content is made freely available for non-commercial purposes, users are allowed to copy and redistribute the material, transform, and build upon the material as long as they cite the source. Push-pull strategies The cabbage seedpod weevil (Ceutorhynchus obstrictus) was introduced to North America from Europe about 70 years ago. B. aeneus adults showed a high tendency towards aggregation in all three years. Over the course of three years (2016–2018), the effects of insecticides on stem-mining weevils [(Ceutorhynchus pallidactylus (Marsham, 1802), Ceutorhynchus napi (Gyllenhal, 1837)] were assessed under field conditions. Control of cabbage stem weevil and pollen beetle with one insecticide application. Google Scholar Vol. Current Contents®/Agriculture, Biology and Environmental Sciences The abundance of the cabbage stem weevil was monitored in field surveys by using yellow water traps between 2007 and 2012 at five locations in Luxembourg.

A new generation of C. pallidactylus emerged from OSR fields in June 2011, while the majority of C. napi emerged in March of the following year. The research showed high resistance of most tested Polish pollen beetle populations to many active substances of all chemical groups of insecticides applied in Poland. Over the course of three years (2016–2018), the effects of insecticides on stem-mining weevils [(Ceutorhynchus pallidactylus (Marsham, 1802), Ceutorhynchus napi (Gyllenhal, 1837 There were no significant differences in the number of settled weevils among the three differently managed fields. Cabbage stem weevil and rape stem weevil are small (<4 mm) dark greyish coloured beetles that are covered in white hairs and feed on brassicas. seed) gave practically complete control of the cabbage stem weevil (Ceuthorhynchus quadridens) on cabbage. The model explains 84% of the variation of the data set. Leave-one-out cross-validation revealed that whether the control threshold was exceeded could be correctly predicted based on the observed temperature differences identified in 22 out of 27 cases (81.5%) in the present study. Researchers investigated a classical biological control program for cabbage seedpod weevil control. MŠMT.

In this way, such a practice can contribute to an increase in OSR damage, and density of the next generation of C. napi. The majority of damage to canola crops is done when larvae feed within pods and destroy developing seeds. Q3 – Plant Sciences years. Therefore, resistance monitoring using bioassays was established in Germany for oilseed rape pest insects. More efficient targeting of insecticides in time and space Thus, it is clear that insecticide treatment directed against B. aeneus and C. pallidactylus is not effective against C. napi.

The spread and intensity of pyrethroid resistance of Meligethes aeneus increased from 2005 onwards, with no sensitive samples left in any region of Germany in 2011. Effective management relies on a combination of these components. provide refuge, food, overwintering sites and alternative prey or hosts for natural enemies. (Toshova et al., 2009; Williams, 2004) have been mentioned as one of the most harmful pests in Europe and Northern America. The cabbage stem weevil Ceutorhynchus pallidactylus (Mrsh.) Delaying the first spring insecticide application till timing II made it possible to combine the control of the stem weevil along with the control of the pollen beetle, Brassicogethes aeneus (Fabricius, 1775). These attack the crop successively at various growth stages and damage different parts of the plant. CrossRef They can be distinguished from cabbage stem weevil (C. pallidactylus) and rape winter stem weevil (C. picitarsis) by their black to dark-brown, rather than reddish-yellow, tarsi. Chemical plant protection is still an indispensable method in effective oilseed rape protection against the pollen beetle (Meligethes aeneus F.) in Poland. Therefore the objective of the study was to determine the present susceptibility level of Polish populations of pollen beetle to the main groups of insecticides recommended in Poland for pollen beetle control. ... Insecticides control damaging insects and nematodes in a variety of crops. The main period of stem weevil settlement is the end of winter and early spring. In all years, males of C. pallidactylus dominated in the traps and the times of beetles' first occurrence. Cabbage Whitefly. 95 1 10 Google Scholar Herrström, G. 1964 Untersuchungen über parasiten von Ölfruchtschädlingen in Schweden Statens växtskyddsanstalt, Meddelanden. Their control is still mainly through the application of chemical However, the poor effectiveness of the tested insecticides on the stem-mining weevils, regardless of the date they were sprayed, indicates it is impossible to successfully control the insect pests with one insecticide application during the seasons with prolonged egg-laying periods. Bibliographie der Pflanzenschutzliteratur (Phytomed database) Besides the standard efficacy analysis expressed through the number of larvae per stem, a damage rating scale was introduced and modelled using a regression model for ordinal categorical data.
