Soil treatments with Metarhizium brunneum EAMa 01/58-Su strain conducted in both Northern and Southern Spain reduced the olive fly (Bactrocera oleae) population density emerging from soil during spring up to 70% treated plots compared controls. A model determine influence of rainfall on conidial wash into different types was developed, most conidia retained at first 5 cm, regardless type, relative percentages recovered ranging between 56 95%. Furthermore, possible effect UV-B exposure time...
RNAi shows potential as an agricultural technology for insect control, yet, a relatively low number of robust lethal targets have been demonstrated to control insects interest. In the current study, selection target genes from iBeetle (Tribolium castaneum) screen were used demonstrate efficacy orthologous in economically important coleopteran pests Diabrotica virgifera and Meligethes aeneus. Transcript orthologs 50 selected analyzed D. v. diet-based bioassays; 21 these showed mortality 36...
Abstract Most studies of insect–pathogen interactions consider the direct interaction between one disease agent and species host. However, given that hosts are subject to challenge from many pathogen/parasite species, mixed infections probably common. In this study, using desert locust two fungal entomopathogen, we show how infection with a largely avirulent pathogen can alter virulence reproduction second, highly virulent pathogen. We find strains vary in their pathogen, depending on order...
Entomopathogenic fungi are sprayed commercially for aphid control in greenhouses. Recently, their ability to grow endophytically within plants was discovered, offering the opportunity systemic biological control. Endophytic colonization of host could also influence life-table parameters and behavior herbivores. We investigated lethal pre-mortality effects Beauveria bassiana Metarhizium brunneum on Aphis gossypii; aphids either received inoculum while feeding recently leaves (surface...
Genetically modified soybean with transgenic event DAS-81419-2 (Conkesta™ technology), expresses two Bacillus thuringiensis (Bt) derived proteins, Cry1Ac and Cry1F. Event is a proposed new Integrated Pest Management (IPM) tool demonstrated high efficacy for controlling the primary lepidopteran pests affecting production in South America. Studies were conducted Brazil from 2011 to 2016 assess of against secondary including Elasmopalpus lignosellus, Agrotis ipsilon Helicoverpa armigera, using...
Bacillus thuringiensis (Bt) event DAS-81419-2 (Conkesta technology) in soybean, Glycine max (L.) Merrill, expresses Cry1F and Cry1Ac proteins to provide protection from feeding by several lepidopteran pests. A total of 27 field experiments across nine locations were conducted 2011 2015 southern central Brazil characterize the efficacy soybean infested with Anticarsia gemmatalis Hübner (Lepidoptera: Erebidae), Chrysodeixis includens (Walker) Noctuidae), Heliothis virescens (F.) Spodoptera...
Abstract This work aimed to optimize olive fruit fly (OFF) Bactrocera oleae (Rossi) (Diptera: Tephritidae) monitoring and integrated management, thereby ensuring optimal less-costly decision-making timely intervention. Field trials in Andalusia (Spain) were undertaken over 2 years trap model, color, size, density for the accurate determination of pest spatial distribution damage as a function cultivar. McPhail traps yellow sticky panels outperformed other 4 models with respect number OFF...
Laboratory studies were conducted to assess the effect of soil moisture and temperature on development preimaginal stages Ceratitis capitata (Wiedemann) (Diptera: Tephritidae). The number days required for immature flies complete their reach adult stage (development time) studied at five temperatures (15, 20, 25, 30, 35°C) under regimes (−2.14 Mpa [mega Pascal] [1% (wt:wt)], −0.5 MPa [5.0% −0.47 [9.0% −0.28 [13.0% −0.23 [17.0% (wt:wt)]). A parametric survival model describing linear...
Maize (Zea mays L.) is one of the most important and widely cultivated crops in Argentina. Fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith), a common maize pest capable causing significant yield losses destructive late-planted subtropical regions, going through five to six generations per growing season. The Bacillus thuringiensis (Bt) trait Herculex I Insect Protection technology by Dow AgroSciences Pioneer Hi-Bred (HX I, event DAS-Ø15Ø7-1), expressing Cry1F protein, was launched...
Abstract Herbicide active ingredients, formulation type, ambient temperature, and humidity can influence volatility. A method was developed using volatility chambers to compare relative of different synthetic auxin herbicide formulations in controlled environments. 2,4-D or dicamba acid vapors emanating after application were captured air-sampling tubes at 24, 48, 72, 96 h application. The extracted from sample quantified liquid chromatography tandem mass spectrometry. Volatility...
Three strains of fungi belonging to the genus Metarhizium Sorokīn (ARSEF 4556, ARSEF 3297, native strain) were assayed against adults and nymphs Neotropical brown stinkbug Euschistus heros (F.) green-belly Dichelops furcatus (F.). The most virulent strain, caused over 90% mortality. average survival time second fifth instar following immersion in 1 × 108 conidia ml-1 was 4.8, 5.7, 5.2 d, respectively. more susceptible than adults. LC50 values median times for adult E. 1.6 107 3.1 6 8 Eggs...
Avian reproduction studies are a regulatory requirement for pesticides in many regions. The data often require careful interpretation due to the nature of study design. Here we present historical control dataset bobwhite quail and mallard duck performed at Evans Analytical Group LLC avian toxicology laboratory over period 1985–2016. analysis demonstrates stability reproductive parameters time good agreement normal ranges as required by test guidelines. major source variation is shown be...
The fish short-term reproduction assay (FSTRA) is an in vivo screen to assess potential interactions with the endocrine system. After a 21-day exposure period vitellogenin (VTG) and secondary sexual characteristics are measured males females. Egg production fertility also monitored daily throughout test. This paper presents data from 49 studies performed satisfy test orders United States Environmental Protection Agency's Endocrine Disruptor Screening Program. Data Evaluation Records were...
The impact of the fungicides mancozeb, myclobutanil, and meptyldinocap on populations Typhlodromus pyri Scheuten was evaluated under field conditions, when applied following good agricultural practices recommended for their use. Two complementary statistical models were used to analyze population reduction compared control: a linear mixed model estimate mean effect fungicide, generalized (proportional odds model) cumulative probability those effects being equal or less than specific IOBC...
