| the multiple target use of spirodiclofen (envidor 240 sc) in ipm pomefruit in belgium. | envidor 240 sc, active ingredient spirodiclofen is a broad spectrum acaricide acting via lipid biosynthesis inhibition (lbi) with no cross resistance to currently available acaricides and with additional insecticidal properties. envidor is positive ipm listed but in frame of resistance management limited to one application per season. in pear growing envidor constitutes an important tool in pear sucker control in a tandem strategy with abamectine. being totally selective on predatory bugs anthoc ... | 2009 | 20218531 |
| kaolin and copper-based products applications: ecotoxicology on four natural enemies. | lethal and sublethal effects of kaolin clays and two copper-based products on four natural enemies found in olive orchards anthocoris nemoralis (f.) (hem. anthocoridae), chelonus inanitus (l.) (hym. braconidae), chilocorus nigritus (f.) (col. coccinellidae) and scutellysta cyanea motschulsky (hym. pteromalidae) are described. both kaolin and copper can be applied for controlling the olive fruit fly and the olive moth, two important pests of this crop. the products did not increase the mortality ... | 2013 | 23415488 |
| new insights of side-effects of tau-fluvalinate on biological agents and pollinators. | a high number of side-effects trials were developed and carried out on beneficial insects and mites by the 'side-effects on beneficial organisms' iobc working group and subsequently published in the iobc bulletins over a number of years. in general, these tests were mainly carried out under laboratory and/or semi-field conditions following the very worst case scenario applications, leading to an iobc classification of 3 (moderately toxic) and 4 (harmful) for many of the tested compounds however, ... | 2015 | 27145571 |
| the selectivity in the time of thiacloprid (calypso 480 sc) applied at preblossom on the further anthocoris nemoralis population build up in pears. | predatory bugs (anthocoris sp.) are key predators of the pear sucker (psyllo pyri) in pear orchards. in order to enhance biological control it is important to verify if crop protection products applied against psylla pyri display potential short- or long-term detrimental effects on anthocoris populations. this study focuses on the impact of thiacloprid (calypso 480 sc), applied at preblossom for the control of the first generation pear sucker psylla pyri, on subsequent population build up of ant ... | 2009 | 20218534 |
| true bugs (hemiptera, heteroptera) as psyllid predators (hemiptera, psylloidea). | data on natural enemies of psyllids are rare and can usually be found in papers about economically significant species. during an investigation of psyllid fauna in serbia, natural enemies were investigated, too. true bugs were the most numerous among them. from 28 psyllid species, 21 species of true bugs from families anthocoridae and miridae were reared. seven species of anthocoridae were identified: anthocoris amplicollis (horváth, 1839), anthocoris confusus reuter, 1884, anthocoris nemoralis ... | 2013 | 24003311 |
| side-effects of commonly used crop protection products in pear on two beneficial miridae bugs. | anthocoris nemoralis, anthocoris nemorum and orius spp. are not the only beneficial predatory bugs inhabiting pear orchards in belgium. quite often, the miridae bugs heterotoma spp. and pilophorus spp. can be found during spring and summer in these orchards, thereby feeding on several pests such as psyllids, aphids, spider mites, ... . side-effects are usually assessed on anthocoris and orius spp., but due to the potential importance of miridae bugs in pest reduction, we tested some commonly use ... | 2015 | 27145577 |
| efficacy of commercially available invertebrate predators against drosophila suzukii. | drosophila suzukii has been recorded in the uk since the end of 2012. to date, reports of serious damage have been rare. previous research has demonstrated that there are chemicals available within the uk that are efficient in dealing with d. suzukii. however, few effective chemicals for use by the organic sector have been identified; equally the addition of "new" insecticides into previously stable ecosystems can have negative impacts upon natural enemies and so disrupt control strategies that ... | 2014 | 26462951 |
| field studies to determine the effects of spinosad on the predatory bugs anthocoris nemoralis and a. nemorum. | the predatory bugs anthocoris nemoralis and a. nemorum are important predators of the pear psylla (psylla pyri) in pear orchards. to effectively control psylla infestations the use of insecticide treatments are often necessary so it is desirable to adopt products and use patterns which protect or conserve natural predator populations. spinosad (the active ingredient in tracer* insecticide) is highly active on psylla when applied up to two times after flowering. to investigate the effects of spin ... | 2006 | 17385510 |
