Field research was conducted in Arkansas to determine the effect of selected rice pesticides on the microbial herbicideColletotrichum gloeosporioides(Penz.) Sacc. f. sp.aeschynomene(henceforth designated C.g.a.) and to integrate C.g.a. into control programs for northern jointvetch [Aeschynomene virginica(L.) B.S.P. # AESVI] in rice (Oryza sativaL.). Water suspensions of dry-formulated spores of C.g.a. at 1.9 × 1011spores/ha were applied midseason in sequence with normal use rates of other pesticides. Carbofuran (2,3-dihydro-2,2-dimethyl-7-benzofuranyl methyl-carbamate) at 0.56 kg ai/ha, propanil (3’4’-dichloropropio-anilide) at 2.2 kg ai/ha, acifluorfen {5-[2-chloro-4-(trifluoromethyl)phenoxy]-2-nitrobenzoic acid} at 0.14 kg ai/ha, or fentin hydroxide (triphenyltin hydroxide) at 0.56 kg ai/ha did not reduce disease development of C.g.a. on northern jointvetch. Sequential applications of benomyl [methyl 1-(butylcarbamoyl)-2-benzimidazolecarbamate] at 0.56 kg ai/ha reduced activity of the fungus on northern jointvetch when fungicide applications began 1 week after C.g.a. application but had no effect on mycoherbicide activity when applications began 2 weeks after C.g.a.

The Relationship

AbstractThe relationship between posttreatment temperatures of 15°, 20°, 25°, and 30°C and toxicity of six pesticides to adult female Phytoseiulus persimilis Athias-Henriot and Tetranychus urticae Koch were studied in the laboratory.The toxicities of cyhexatin, dicofol, propargite, citrazon, chlorobenzilate, and per-methrin were positively correlated with temperature. Except for propargite and permefhrin, P. persimilis was less susceptible than T. urticae at 15° and 20°C, but equal in susceptibility at 25° and 30°C.The results obtained may indicate a potential value of posttreatment temperature manipulation as a useful adjunct to integrated pest control programs in glasshouses.

The design of orchard pest control programs that favor natural enemies is based partly on a knowledge of the toxicity of spray chemicals to beneficial arthropods. This paper summarizes the results of tests conducted during the past five years to determine toxicities, and it includes some previously published data (MacPhee and Sanford 1954 and 1956). Tests were discontinued after 1955 on the species Stethorus punctum (Lec.), Euderus spp., Scambus spp., and Trichograma minutum Riley and on the chemical formulations Aramite, Chlorocide, Erad, fixed nicotine, lime sulphur, Puratized Agricultural Spray, summer oil, and synthetic cryolite. Tests were initiated on the phytoseiids Typhlodromus finlandicus (Oudms.) and T. rhenanus (Oudms.), and the mirid Psallus sp., and also on the pesticides Bacillus thuringiensis Berliner preparation, demeton, Diazinon, dodine, Kelthane, Kepone, Rhothane, Sevin, Tedion, Trithion and zineb. Typhlodromus pyri Scheuten was previously reported as T. tiliae (Oudms.), a synonym, and Atractotomus mali (Meyer) is an authoritative identification of the species previously listed as Criocoris saliens (Reuter).

ABSTRACTBACKGROUNDEradication of invasive alien species is a form of pest control linked to biodiversity conservation that usually involves killing animals. Squirrels are prominent among invasive alien species in Italy with four species introduced. Three of them are included within the list of alien species of European concern and their eradication and control is recommended. However, their local control is not an easy task, being highly appreciated by the general public. We propose a socio-ecological approach to evaluate the feasibility of eradicating Siberian chipmunks (Eutamias sibiricus) populations. We performed a structured questionnaire to assess the social perception of invasive Siberian chipmunks in urban parks where they occur and to identify groups of visitors who might oppose eradication. We also carried out geographic profiling to test for the spatial expansion of chipmunk populations.RESULTSOverall, park visitors regarded chipmunks positively and appreciated to see them, but human-chipmunk interactions were still rare. We did not identify any group of visitors with a strong attachment to chipmunks, who might oppose future control programs. Geographic profiling showed that chipmunks in Valeggio sul Mincio are starting to expand outside of their introduction site.CONCLUSIONSData from questionnaires show that chipmunks eradication, coupled with adequate communication initiatives, might be feasible. Moreover, geographic profiling indicates that time for a rapid removal is running out. Socio-ecological approaches, combining the analysis of structured questionnaires administered to stakeholders and statistical modeling of pest observations, could be a valuable tool to decide the feasibility and the urgency of invasive pest control.
