Porter, Sanford - - 2010
The Formosa biotype of the decapitating fly Pseudacteon curvatus Borgmeier was released and successfully established as a self-sustaining biocontrol agent of the red imported fire ant Solenopsis invicta Buren at several sites around Gainesville, FL in 2003. In order to determine the status of these releases, 59 sites were surveyed ...

Pest management of insects and mites on orchids has been based on the use of synthetic organic pesticides. However, less-toxic chemical control is needed by hobbyists and small growers. Orchids from 8 genera were treated with Silwet L-77 alone and no evidence of phytotoxicity was seen. Subsequently, 3 petroleum oils ...

Honey baits were used to assess the activity and abundance of nectar-drinking ants in fire successional habitats of rocklands on Andros Island, Bahamas. Vegetation was sampled in pineyard and coppice habitats (the same communities as Florida's pine rocklands and hammocks), revealing a larger proportion of taxa with extrafloral nectaries in ...

Red imported fire ant, Solenopsis invicta Buren, workers were sampled from 26 colonies in Virginia during the 2007-2008 time period. Polymerase chain reaction (PCR) assays were used to determine colony social form (monogyny or polygyny) by genotyping ants at the Gp9 locus. Twenty of the colonies (76.9%) were found to ...

Evaluation of combinations of flower odor compounds in northern Florida revealed that linalool was synergistic in attractiveness with phenylacetaldehyde (PAA) to the migratory moth velvetbean caterpillar (Anticarsia gemmatalis Hubner). This noctuid was the most common species collected from traps with a binary lure composed of PAA and linalool, with over ...

A major obstacle for many studies examining sperm competition and cryptic female choice in insects has been the identification and quantification of sperm stored in the sperm storage organs of females that have mated with two or more males. Historically, sexual selection studies have focused primarily on paternity outcomes for ...

The root weevil Diaprepes abbreviatus (L.) has been reared since 1992 on an artificial diet first reported in 1982. Recently, we have shown that several ingredients included in the original diet have little or no effect on insect performance. Here we examined the effects of 2 principal drivers (cottonseed meal ...

The neem tree Azadirachta indica A. Juss produces numerous allelochemical compounds. The most effective active ingredient in A. indica based insecticides is azadirachtin. We found that azadirachtin did not cause mortality, antifeeding responses, or change growth rate of Melanotus communis (Gyllenhal) wireworms. However, azadirachtin treated soil was repellent to the ...

Pupal parasitism of the apple ermine moth, Yponomeuta malinellus Zeller (Lepidoptera: Yponomeutidae), was investigated in northeast Asia with the goal of identifying potential biological controls of the moth, which threatened the apple industry in Washington State, USA during the 1980s. Seven primary and 2 secondary parasitoids were recorded from 27, ...

The sterile insect technique (SIT) is widely used to suppress or eradicate target insect pest populations. The effectiveness of SIT depends on the ability of the released sterile males to mate with and inseminate wild females. Irradiation is effective for sterilizing mass-reared insects, and the negative impacts of this procedure ...

Huanglongbing (citrus greening) is one of the most serious diseases of citrus. Movement of the disease occurs as a result of natural transmission by the insect vector and by movement of infected plant material. We demonstrate here that Diaphorina citri Kuwayama, the vector of citrus greening pathogens, can be transported ...
Hoy, Marjorie - - 2010
A fungal pathogen that killed adult Diaphorina citri Kuwayama (Asian citrus psyllid) in Florida citrus groves was isolated, characterized molecularly and morphologically and identified as a novel isolate of Isaria fumosorosea (Ifr) (= Paecilomyces fumosoroseus) from the Asian citrus psyllid (Ifr AsCP), but no concentration-mortality or time-response data were obtained. ...
Hodges, Gregory - - 2010
A new soft scale genus Phalacrococcus Hodges & Hodgson gen. nov. and a new species Phalacrococcus howertoni Hodges & Hodgson sp. nov., is described from Florida, United States. The adult female and adult male, male and female second-instars, first-instars, and pupa are described and illustrated. Host records, biology, and distribution ...

The lobate lac scale, Paratachardina pseudolobata Kondo & Gullan, attacks large numbers of plants in Florida. The scales primarily infest the branches and main stems <2 cm in diameter; rarely were they found on stems that were larger than 4 cm in diameter or on leaves and never on roots. ...

Background & objectives: The metabolic syndrome (MS) is a risk factor for development of cardiovascular disease and is closely associated with obstructive sleep apnoea (OSA). Co-occurrence of both OSA and MS is called syndrome Z. It has been hypothesized that the OSA may be a manifestation of MS. We collected ...

Background & objectives: Conjugated linoleic acid (CLA) reduces fat deposition in the body, but the mechanism of action is not clear. The present study was conducted to investigate the effects of CLA on body fat metabolism. Since milk fat is the best natural source of dietary CLA, intervention of non-fat ...

Background & objective: In India, National AIDS Control Organization (NACO) introduced syndromic approach to treat patients with abnormal vaginal discharge without a need for laboratory tests. Simple tools like pH test and Whiff test can be done without high expertise, microscope and even speculum. This can improve diagnostic value of ...

Background & objectives: The present work was undertaken to evaluate antiplasmodial activity of ethanolic leaves extract of traditional medicinal plant Ajuga bracteosa in Plasmodium berghei infected BALB/c mice along with its phytochemical screening and acute toxicity test to support its traditional use as a remedy for malaria.
Dua, V.K. - - 2010
Background & objectives: Development of insect resistance to synthetic pesticides, high operational cost and environmental pollution have created the need for developing alternative approaches to control vector-borne diseases. In the present study we have investigated the insecticidal activity of essential oil isolated from the leaves of Lantana camara against mosquito ...

Background & objectives: Pulmonary involvement due to leptospirosis carries high case fatality rate and is the commonest cause of death due to leptospirosis. Immune mechanisms play a key role in the pathogenesis of leptospiral pulmonary haemorrhage. As other immune pulmonary haemorrhages due to non leptospiral causes are treated with plasma ...

Background & objectives: Sources of autologous tissue that can functionally replace the corneal epithelium have been considered as an alternative to allogenous limbal transplants for limbal stem cells deficiency (LSCD). The aim of the present study was to compare the characterization of oral mucosa with limbal epithelial cells by markers ...

Background & objectives: Ampullary cancer is one of the periampullary tumours with better prognosis, but relapses occur early in some patients. This study was carried out to assess whether pancreatoduodenectomy (PDE, Whipple operation) could be a safe therapeutic procedure for elderly patients with periampullary tumours.
