Planting Date of Cotton in the Brazilian Cerrado Drives Boll Weevil (Coleoptera: Curculionidae) Infestation.

Although the boll weevil (BW), (Coleoptera: Curculionidae) has been attributed to the significant losses caused to cotton yield in the Americas, the categorization as a quarentenary pest in places where it is still not occurring has increased its relevance worldwide. In areas where it is widespread, pest suppression relies on many broad-spectrum insecticide applications. However, other control tactics are sought.

Spatio-temporal distribution of Anthonomus grandis grandis Boh. in tropical cotton fields.

Background: Knowledge of the spatio-temporal distribution of pests is important for the development of accurate management approaches. The boll weevil, Anthonomus grandis grandis Boh., is a deleterious cotton, Gossypium hirsutum L.

Spatial distribution and colonization pattern of Bemisia tabaci in tropical tomato crops.

Background: In precision integrated pest management, management tactics are implemented only where and when needed, by identifying the sites where the pest population has reached economic thresholds. Tomato, Solanum lycopersicum (Linn.), is a vegetable cultivated worldwide, but its production is reduced by insect pests such as the whitefly, Bemisia tabaci (Genn.

Economic injury levels and economic thresholds for Leptoglossus zonatus (Dallas) (Hemiptera: Coreidae) infesting seed maize.

Background: Although Leptoglossus zonatus is considered a secondary pest of maize grown for grain, when grown for seed, this pest can cause significant economic damage. There are no records of management recommendations for this pest. The objectives of this work were to quantify losses caused by L.

[Burnout in Portuguese Healthcare Professionals: An Analysis at the National Level].

Introduction: Burnout is a psychological syndrome, characterized by a state of high emotional exhaustion, high depersonalization and low personal accomplishment, which leads to erosion of personal, professional and health values. This study reports the incidence of burnout in Portuguese Healthcare professionals.

Material And Methods: Burnout in Portugal's health professionals was assessed with the Maslach Burnout Inventory - Human Services Survey, using a zero (never) to six (always) ordinal scale, on a sample of 1 262 nurses and 466 physicians with mean age of 36.

Rational Practices to Manage Boll Weevils Colonization and Population Growth on Family Farms in the Semiárido Region of Brazil.

Because boll weevil, Anthonomus grandis Boh. develops partially protected inside cotton fruiting structures, once they become established in a field, they are difficult to control, even with nearly continuous insecticide spray. During two cotton-growing seasons in the Semiárido region of Pernambuco State, Brazil, we tested the use of kaolin sprays to disrupt plant colonization through visual cue interference, combined with removal of fallen fruiting bodies to restrain boll weevil population growth after colonization.

Borrowing, adapting, and learning the practices of smallpox: notes from colonial Goa.

In this article I will address colonial state policies toward smallpox in nineteenth-century Goa. The picture that emerges from the analysis of health services documents suggests a broad variety of coexisting practices. While the actions of some of the Portuguese head physicians epitomized the conflict between state-sponsored vaccination policies and local preferences for smallpox inoculation, others showed sympathy for and developed arguments in favor of inoculation as practiced by indigenous experts.

[Occurrence of Planococcus minor Maskell (Hemiptera: Pseudococcidae) in cotton fields of northeast region of Brazil].

The mealybug Planococcus minor Maskell is a significant pest of more than 250 cultivated plants belonging to at least 80 families. Among the host plants several Malvaceae species are attacked, including the genera Gossypium. In 2005 and 2006 the mealybug P.

Spotted-dick, a zinc-finger protein of Drosophila required for expression of Orc4 and S phase.

The highly condensed chromosomes and chromosome breaks in mitotic cells of a Drosophila mutant, spotted-dick/pita, are the consequence of defects in DNA replication. Reduction of levels of Spotted-dick protein, by either RNAi or mutation, leads to the accumulation of cells that have DNA content intermediate to 2N and 4N in proliferating tissues and also compromises endoreduplication in larval salivary glands. The Spotted-dick Zinc-finger protein is present in the nuclei of cells committed to proliferation but necessary in cells undertaking S phase.

Selectivity of pesticides used on cotton (Gossypium hirsutum) to Trichogramma pretiosum reared on two laboratory-reared hosts.

The side-effects of pesticides (insecticides, fungicides, herbicides and plant growth regulators) used on cotton were tested on adults and pupae of Trichogramma pretiosum Riley reared in the laboratory on two different hosts, the Angoumois grain moth (Sitotroga cerealella Olivier) and the Mediterranean flour moth (Ephestia kuehniella (Zeller)). The eggs of the host enclosing the parasitoid pupae received direct pesticide sprays, while the adults of the parasitoid were exposed to the pesticides through contact with residues on sprayed eggs offered to parasitism. Alpha-cypermethrin, carbosulfan, deltamethrin, endosulfan, profenofos and zeta-cypermethrin were highly noxious to the parasitoid, significantly reducing the percentage of emergence and parasitism of T.
