Toxicity and Binding Studies of Bacillus thuringiensis Cry1Ac, Cry1F, Cry1C, and Cry2A Proteins in the Soybean Pests Anticarsia gemmatalis and Chryso…
2017
ABSTRACT Anticarsia gemmatalis (velvetbean caterpillar) and Chrysodeixis includens (soybean looper, formerly named Pseudoplusia includens ) are two important defoliating insects of soybeans. Both lepidopteran pests are controlled mainly with synthetic insecticides. Alternative control strategies, such as biopesticides based on the Bacillus thuringiensis (Bt) toxins or transgenic plants expressing Bt toxins, can be used and are increasingly being adopted. Studies on the insect susceptibilities and modes of action of the different Bt toxins are crucial to determine management strategies to control the pests and to delay outbreaks of insect resistance. In the present study, the susceptibilitie…
Specific binding of Bacillus thuringiensis Cry1Ea toxin, and Cry1Ac and Cry1Fa competition analyses in Anticarsia gemmatalis and Chrysodeixis include…
2019
AbstractAnticarsia gemmatalis (velvetbean caterpillar) and Chrysodeixis includens (soybean looper) are two important defoliation pests of soybeans. In the present study, we have investigated the susceptibility and brush border membrane-binding properties of both species to Bacillus thuringiensis Cry1Ea toxin. Bioassays performed in first-instar larvae demonstrated potent activity against both soybean pests in terms of mortality or practical mortality. Competition-binding studies carried out with 125Iodine-labelled Cry1Ea, demonstrated the presence of specific binding sites on the midgut brush border membrane vesicles (BBMV) of both insect species. Heterologous competition-binding experiment…
Novel mutations in the voltage-gated sodium channel of pyrethroid-resistant Varroa destructor populations from the Southeastern USA
2016
The parasitic mite Varroa destructor has a significant worldwide impact on bee colony health. In the absence of control measures, parasitized colonies invariably collapse within 3 years. The synthetic pyrethroids tau-fluvalinate and flumethrin have proven very effective at managing this mite within apiaries, but intensive control programs based mainly on one active ingredient have led to many reports of pyrethroid resistance. In Europe, a modification of leucine to valine at position 925 (L925V) of the V. destructor voltage-gated sodium channel was correlated with resistance, the mutation being found at high frequency exclusively in hives with a recent history of pyrethroid treatment. Here,…
Mutations in the voltage-gated sodium channel gene associated with deltamethrin resistance in commercially sourced Phytoseiulus persimilis
2020
The implementation of Integrated Pest Management (IPM) in current agricultural practice is a convenient and very effective strategy to maintain pest populations under control. The use of Biological Control Agents, like Phytoseiulus persimilis, is key for the success of such approach. This predatory mite is widely used since it is very effective for controlling the two spotted spider mite (Tetranychus urticae), one of the most devastating pests worldwide. Here we show the identification of mutations located in the Voltage Gated Sodium Channel (VGSC) of P. persimilis, that correlate with the reduced susceptibility to deltamethrin observed in commercially sourced colonies of this predatory mit…
No exception to the rule: Candidatus Portiera aleyrodidarum cell wall revisited
2014
International audience; Many insect endosymbionts described so far are gram-negative bacteria. Primary endosymbionts are obligatory bacteria usually harboured by insects inside vacuoles in specialized cells called bacteriocytes. This combination produces a typical three-membrane system with one membrane derived from the insect vacuole and the other two from the bacterial gram-negative cell envelope, composed by the cell wall (the outer membrane plus the periplasmic space) and the plasma membrane (the inner membrane). For the last 21 years, the primary endosymbiont of whiteflies 'Candidatus Portiera aleyrodidarum' was considered an exception to this rule. Previous works stated that only two …
A case of cefditoren‐induced Acute Generalized Exanthematous Pustulosis during COVID‐19 pandemics. Severe Cutaneous Adverse Reactions (SCARs) are an …
2020
Abstract We read with interest the article by Recalcati et al. about the report of cutaneous manifestations in COVID‐19 patients. We would like to highlight that some potentially severe manifestations in these patients are not directly related to the coronavirus but to the medications administered.
Risk factors for anthroponotic cutaneous leishmaniasis in unresponsive and responsive patients in a major focus, southeast of Iran
2018
Cutaneous leishmaniasis (CL) is a serious health challenge at the global level due to Leishmania tropica. This study was conducted to evaluate the risk factors associated with anthroponotic CL (ACL) in unresponsive (patient who does not heal and remains with an active lesion, despite receiving two courses of intra-lesional Glucantime along with cryotherapy and one cycle of systemic Glucantime) and responsive patients in a major focus in southeastern Iran. A case-control study was conducted from April 2015 to October 2016 in the southeast of Iran. Patients were recruited in a major ACL focus from unresponsive and responsive cases. These patients were compared for environmental, clinical, and…
The Current and Future Role of Carsharing in Palermo: Analysis of Collected Data and Results of a Customer Satisfaction Survey
2018
In recent years many cities, both in Italy and abroad, have adopted Sustainable Urban Mobility Plans, in which one of the key action is the developing of the sharing mobility. The aim of the paper is to define the role that carsharing plays in Palermo today and it will play in the future, thanks to the adoption of new strategies, such as the introduction of the free-floating system, and transport demand orientation policies, such as the increase in the parking fees for private cars or the expansion of the ZTL. The average user profile of carsharing in Palermo has been identified through a customer satisfaction survey and the potential demand of carsharing in Palermo has been studied using G…
El macro-modelat de la costa carbonàtica de Victòria (Austràlia): paral.lelismes i diferències amb les cales baleàriques
2019
Les cales són penetracions marines, preferentment a un litoral carbonatat de caràcter tabular, arran de la inundació eustàtica d’un antic curs fluvial en la morfogènesi de les quals, de més a més del paper de la fracturació distensiva i la carstificació, també hi participen els mecanismes de col·lapse i la dinàmica litoral així com les variacions glacio-eustàtiques del nivell marí, especialment durant el Quaternari. El present treball aborda la tipologia i característiques dels elements del macro-modelat de la costa rocosa de Victòria (sud d’Austràlia) i les compara amb els antecedents i el coneixement obtingut en l’estudi de les cales de la Mediterrància occidental, principalment les de le…
"Frater, ave atque vale" (Catull. 101.10): fortuna literaria de una fórmula epigráfica
2011
Trabajo realizado dentro del Grupo de Investigación «Tradiciones Clásicas» de la UPV/EHU (GIU-07-26) [ES] En este artículo ofrecemos un panorama con algunos de los autores modernos –Tennyson, Swinburne, V. Woolf, G. Moore, C.K. Stead y Anne Carson– que han dado nueva vida al motivo del saludo directo al difunto, a partir del carmen 101 de Catulo, cuyo verso 10 sigue gozando de un especial éxito, apoyado por la efectiva simplicidad de su saludo emotivo al hermano y de su forma, asequible y reconocible aun cuando el conocimiento de la lengua latina sea menor. [EN] In this article we offer an overview of some of the modern authors (specially Tennyson, Swinburne, V. Woolf, G. Moore, C.K. Stead,…
