The invention particularly relates to synergistic arthropodicidal compositions containing several pyrethroidal active ingredients which are not toxic to warm-blooded organisms. The compositions contain as a pyrethroidal active ingredient 1StransR-alpha-cyano-3-phenoxy-benzyl~ 3-/2,2-dichlorvinyl/-2,2-dimethyl-cyclopropane carboxylate of the Formula I CI :c=ch CI and tetramethrin or trans-tet/amethrin of the Formula II CH3x. OCH CH3 II. and optionally a further pyrethroidal substance as well as piperonyl butoxide of the Formula III and optionally additives. CH2OCH2CH20CH2CH2OCZf H9 III. CH2CH2CH3 The compound of the Formula I amounts to 0.1-20 % by weight and the compound of the Formula II to 0.05-100/0 by weight and the piperonyl butoxide of the Formula III amounts to 0.1-40% by weight. The remaining amount up to 100% consists of additives. The following abbreviations are used throughout the specification: Alphaniethrin = /S/-alpha-cyano-3-phenoxybenzyi-/1R,3R/-3/2,2-dichlorvinyl/-2,2-dimethylcyclopropane- carboxylate and /R/-a|pha-cyano-3-phenoxy-benzyl-/1S,3S/-3/2,2-dichlorvinyl/-2,2-dimethyl-cyclopropane carboxylate TET =*= tetramethrin = 3,4,5,6-tetrahydro-phtalimido-methyl/1RS/-cis-trans-chrysanthemate deltamethrin = /S/-alpha-cyano-3-phenoxy-benzyl/1R,3R/-3-/2,2-dibrombinyl/-2,2-dimethyl-cyclopropane EP 0 327 467 A2 carboxylate trans TET = trans tetramethrin = 3,4,5,6-tetrahydro-phtalimidomethyl/1RS/-trans chrysanthemate TRX = transmix = a mixture of 1StransR-alpha-cyano-3-phenoxy-benzyl-3-/2,2-dichlorvinyl/-2,2-dimethyl cyclopropane carboxylate and 1 RtransS-alpha-cyano-3-phenoxy-benzyl-3-/2,2-dichlorvinyl/-2,2-dimethyl-cy- clopropane carboxylate 5 SF = synergistic factor PBO - piperonyl butoxide The composition according to the invention may be used in all those locations wherein only such substances may be applied which are substantially not toxic to warm-blooded organisms, such as agricultural and horticultural pests, i.e. pests occurring in preserved food industry and refrigerating industry. Various 10 parasitic arthropodal pests cause significant harm in stock breeding. By disquieting the animals the pests cause a reduction of their yield capacity, their gain in weight, they disturb their behaviour and their technology tolerance increasing thereby the number of compulsory slaughtering. Significant yield losses are caused by the store arthropoda as well, and this is worsened by the fact that these crops are already produced /i.e. costs are already involved/ and the protection is needed for the whole provision storing period during the utilization 15 of the crops to avoid the presence of substances being harmful for men and animals in provision. During the protection against diseases propagated by various arthropoda such as malaria, yellow disease, sleeping disease, dysentery, plague, it is important that only such agents may be applied which are not toxic to warm-blooded organisms, are intoxic dermally, do not cause dermal irritation and allergy. As the most widely used insecticides are neuroactive substances /nerve poison/ the function of such 20 nerves is damaged which can be found in both inferior and superior animals /F. Matsumura: Differential toxicities of insecticides and halogenated aromatics, Pergamon Press 1984/. Consequently, the selectivity of most of the compositions is not sufficient. The compositions according to the invention show an outstanding activity against the following pests: flies such as Hydrotaea irritans, Morellia simplex, M. Hortorum, Haematobla spp., Stomoxys calcitrans, Musca 25 domestica, M. autumnalis, Glossina app., Simulium spp., Culicoides, Phlebotomus spp., Tabanidae/; fleas such as Xenopsylla spp., Pulex spp., Ctenocephalides app./; bugs such as Cimex spp., Triatoma spp., Rhodnius spp., Triatoma spp./; louses such as Pediculus spp., Phthirius pubis, Damalinia, Haematophinus; ticks resp. mites such as Ixodes, Sporoptes spp., scabiei; mosquitoes such as Anopheles spp., Aedes spp., Culex spp., Mansonia spp.; cockroaches such as Blattella germanica, Blatta orientalis, Periplaneta americana, 30 Periplaneta australasie, Supella longipalpa; various store pests such as Tribolium spp., Trogoderma spp., Stegobium spp., Sitophilus spp., Tenebrio spplk, Stagobium paniceum, Sitotroga cerealella, Zaorotes subfasciatus, Rhyzopertha dominica, Ptinus spp., Cryzaephilus surinamensis, O. mercator, Lasioderma serricorne, Necrobia spp., dermestes spp., Carpopohilus spp., Dryptolestes spp., Mezium spp., Alphitobius diapersinus, A.laevigatus, Callosobruchus spp., Bruchus spp., Anthrenus verbasci, Ephestia spp., Plodia 35 interpunctella, Acaris siro, Tyrophagus putres, T.centiale, T.longinor, Tyrolichus casei; agricultural pests belonging to genera Lepidoptera, Coleoptera, Heteroptera, Homoptera, Hymenoptera, Diptera and Acariformes. A preferred form of the composition according to the present invention contains as a further active ingredient 1RtransS-alpha-cyano-3-phenoxy-benzyl-3-/2,2-dichlorvinyl/-2,2-dimethylcyclopropane-carboxy- 40 late in an amount of 0.1-20% by weight. The ratio of IStransR to IRtransS amounts to 0.7-1.3:1.3-0.7, preferably 1:1. We have now found that IStransR isomer being the least active out of the 4 trans isomers of cypermethrin can be transformed to a synergistic active and stable composition when combined with tetramethrin and piperonyl butoxide. Thus the advantages of the very low toxicity against warm-blooded animals can be utilized 45 and outstanding selective arthropodicidal composition may be prepared. The data relating to synergistic compositions are shown in Table 1. 3 EP 0327 467 A2 Table 1 Interaction of transmix isomers and piperonyT butoxide on house fly /Musca domestica/ tested by topical method isomers activity activity with PBO/1:2/x and active without ingredient PBO 10 mixtures LDsom resp. ng/fly ng/fly SF IRtransS 5.78 4.58 1.26 IStransR 571.50 278.62 2.05 TRX 6.70 3.76 1.78 TRX+TET 8.02 2.97 2.70 (10|1) TRX+TET 8.41 2.87 2.93 (10;5) x =1 calculated to trans cypermethrins As excipients anionic tensides, such as calcium alkyl aryl sulfonate, calcium dodecyl benzene sulfonate or 25 non-jonic surfactants such as nonyl or dinonyl phenol ethoxylates /EO = 16-20/ are used. The composition may contain further non-ionic components such as tristyryl phenol ethoxylates /ED = 20/ etc. As filling agent the composition may contain solvents such as xylene, aromatic solvent mixture, aliphatic hydrocarbon mixtures, alkyl benzene, mineral or vegetable oile and solid carriers etc. The formulation of the composition depends on the method of application. In order to prepare emulsifiable 30 qompositions anionic tensides, non-ionic surfactants and other non-jonic components and solvents are preferable admixed to the mixture. As anionic tensides 2 to 5 % by weight of calcium alkyl aryl sulfonate, and as non-ionic surfactant 1 to 2 % by weight of nonyl-, dinonyl phenol ethoxylates /EO = 16-20/ and as further non-jonic components 0.5-2 o/o by weight of tristyryl phenol ethoxylates (EO = 20/ and as solvent xylene may preferably be used. 35 A transparent emulsifiable composition may be prepared by using as anionic tenside 2.5-9 % by weight of a calcium salt of alkyl aryl sulfonate,, and as non-ionic surfactant 1 .25-3.5 % by weight of nonyl-, dinonyl phenol ethoxylates /EO = 16-20/ and as further non-ionic component 0.7-3.5 % by weight of tri-styryl phenol ethoxylates /EO = 20/ and as solvent preferably 5-10 % by weight of xylene, 1-3 % by weight of ethylene glycol and water up to 100% by weight. 40 Wettable powders can also be prepared by adding dispersing agents and carriers. According to a preferred feature as dispersing agent 1-2 % by weight of dioctyl sulfosuccinate and 6-8 % by weight of polymerized sodium naphtaline sulfonate and as carrier silicic acid and talc may be used.

The aim of the study was to determine the biodiversity of flies (Diptera) occurring in livestock buildings and in their direct proximity, in various systems of ruminants rearing. Flies were collected by net sweeping during the summer, in two cowsheds (one large-scale, and one traditional farm), and one specialist sheepfold, located in the Lesser Poland region of Poland. The insects were captured – both inside and outside the premises – three times (at 10:00, 12:00 and 14:00) on selected warm and sunny days of June, July and September, when animals were assumed to be the most harassed. A total of 18365 flies belonging to 13 families were obtained. The largest relative abundance of Diptera were from the Drosophilidae family (61.4%), and dominating Muscidae species – Musca domestica L., 1758 (19.2%) and Stomoxys calcitrans (L., 1758) (5.7%). More than half (55.5%) of all flies were captured in the morning, and their vast majority not inside a livestock building (28.2%), but in its close proximity (71.8%).

  • Cheshire Wildlife Trust
    Cheshire Wildlife Trust Heteroptera and Diptera surveys on the Manchester Mosses with PANTHEON analysis by Phil Brighton 32, Wadeson Way, Croft, Warrington WA3 7JS [email protected] on behalf of Lancashire and Cheshire Wildlife Trusts Version 1.0 September 2018 Lancashire Wildlife Trust Page 1 of 35 Abstract This report describes the results of a series of surveys on the Manchester mosslands covering heteroptera (shield bugs, plant bugs and allies), craneflies, hoverflies, and a number of other fly families. Sites covered are the Holcroft Moss reserve of Cheshire Wildlife Trust and the Astley, Cadishead and Little Woolden Moss reserves of Lancashire Wildlife Trust. A full list is given of the 615 species recorded and their distribution across the four sites. This species list is interpreted in terms of feeding guilds and habitat assemblages using the PANTHEON software developed by Natural England. This shows a strong representation in the sample of species associated with shaded woodland floor and tall sward and scrub. The national assemblage of peatland species is somewhat less well represented, but includes a higher proportion of rare or scarce species. A comparison is also made with PANTHEON results for similar surveys across a similar range of habitats in the Delamere Forest. This suggests that the invertebrate diversity value of the Manchester Mosses is rather less, perhaps as a result of their fragmented geography and proximity to past and present sources of transport and industrial pollution. Introduction The Manchester Mosses comprise several areas of lowland bog or mire embedded in the flat countryside between Warrington and Manchester. They include several areas designated as SSSIs in view of the highly distinctive and nationally important habitat, such as Risley Moss, Holcroft Moss, Bedford Moss, and Astley Moss.

Together with the families Anthomyiidae and Scathophagidae these constitute the superfamily Muscoidea. Overall statistics on recording activity are given by decade and hectad. Checklists are presented for each of the three Watsonian vice-counties 58, 59, and 60 detailing for each species the number of occurrences and the year of earliest and most recent record. A combined checklist showing distribution by the three vice-counties is also included, covering a total of 241 species, amounting to 68% of the current British checklist. Biodiversity metrics have been used to compare the pre-1970 and post-1970 data both in terms of the overall number of species and significant declines or increases in individual species.

  • Cheshire Wildlife Trust
    Cheshire Wildlife Trust Heteroptera and Diptera surveys in the Delamere Forest, 2013-2017 by Phil Brighton 32, Wadeson Way, Croft, Warrington WA3 7JS [email protected] on behalf of Cheshire Wildlife Trust Version 1.0 October 2017 Page 1 of 30 Abstract This report provides the results of a series of heteroptera and diptera surveys carried out in the Delamere Forest itself and some of the satellite woodland and bogs. A full list is given of the 460 species recorded and their distribution across the surveyed area. This species list is interpreted in terms of habitat assemblages using the PANTHEON software recently made available by the Biological Records Centre. This showed a strong representation of wet woodland species in the sample. The national assemblages of peatland and decaying wood species were much less well represented but included a higher proportion of rare or scarce species. Of particular note was the find in 3 new locations of the hoverfly Orthonevra intermedia: Delamere remains the only known British location for this species following the original discovery in 2003. The Red Databook cranefly Idioptera linnei was found at Abbots Moss for the first time since 1969, only the second record in the Delamere area since then. Both these species should benefit from the restoration of the Delamere mossland. Introduction In 2003, at an early stage of the Delamere Lost Mosses project Martin Drake was commissioned to carry out an extensive survey of terrestrial invertebrates across the Delamere area1. The bulk of the records from this survey were of beetles (Coleoptera) and true flies (Diptera), but other orders were also covered.
