As part of a study investigating experimental insecticide formulations for control of Argentine ants, Linepithema humile (Mayr), in outdoor locations, the imidacloprid-based product Premise 2 (Bayer Environmental Science) was used as a commercial standard. During the study, Premise 2 provided the mo...
The fire-ants are widely distributed in Brazil, including urban areas, but few studies are found in this country. The Solenopsis saevissima species-group encompasses ecologically and economically important ants, and has the largest number of species of the genus Solenopsis. In Brazil, the main speci...
Solenopsis invicta viruses (SINVs) were surveyed in samples collected in municipalities of São Paulo and Minas Gerais States, Brazil, using a multiplex RT-PCR method. Species identification was performed by mitochondrial COI gene sequencing. All three SINVs described in the US were detected in Brazi...
Solenopsis species have a worldwide distribution; some species of the S. saevissima species group, native from South America and popularly known as fire ants, had been introduced accidentally in several countries worldwide. This species group is widely distributed in Brazil, including in urban areas...
Solenopsis ant genus has a worldwide distribution but species from S. saevissima species group native to South America, and popularly known as fire ants, have been introduced accidentally in several countries worldwide. Despite a high diversity species in the Neotropical region, their ecology and li...
The invasive ant species complex was determined within three Puerto Rican housing developments of different ages (one, four, and eight years old). Frequency and relative abundance data were collected from each site. A total of 19 different ant species were identified from the sites, with the major p...
Darwin is the largest city in northern Australia, located above the tropic of Capricorn and experiences a tropical monsoon climate. A wide range of invasive and nuisance ants are present in and around Darwin and considered significant urban pests. These include African Bigheaded Ant (Pheidole megace...
The growing concern of consumers about the use of traditional insecticides has increased need for development of safe, effective, and natural insecticides and repellents. Plant extracts containing essential oils have been used for centuries to kill and repel a variety of insect pests including cockr...
Choice experiments determined sucrose bait base preference by using laboratory colonies of 10 species of urban pest ants, namely Monomorium pharaonis (L.), Monomorium floricola (Jerdon), Monomorium destructor (Jerdon), Monomorium orientale Mayr, Tapinoma indicum (Forel), Tapinoma melanocephalum (Fab...
Sucrose intake rate and percent effort (a variable which describes the amount of energy an insect uses to feed on a liquid) was quantified for Solenopsis invicta Buren. In other words, how much energy does the insect gain and how much energy is lost in the feeding event? In order to understand this ...
Metaflumizone (proposed common name) is a high performance insecticide submitted for crop registration approval in the USA in 2004. Other key country registration submissions are expected to follow the USA application.Toxicological and environmental studies indicate that there is low risk to applica...
The benzoylphenyl urea insect growth regulator (IGR) noviflumuron and the fast-acting insect neurotoxicant spinosad were field tested separately and in combination to determine efficacy against the Red Imported Fire Ant (RIFA), Solenopsis invicta Buren. Two separate trials were conducted in three se...
In Louisiana, 115 chemicals are registered for use against red imported fire ants,Solenopsis invicta, and other pest ants such as Argentine ants, Linepithema humile. Yet citizens and pest control operators still struggle with adequate control of ant pests in homes, nursing facilities, hospitals, and...
Questionnaire-based surveys of homeowners revealed that ants were the most economically important and abundant household pest after mosquitoes and cockroaches in Malaysia. Twenty-five species of ants were found indoors and outside buildings; all species nest outdoors except Monomorium pharaonis, Mon...
Demand CS® (lambda-cyhalothrin) has been designed specifically for use in urban pest management. The product is based on microencapsulation technology which encloses the liquid active ingredient in a polymer shell to provide protection against hostile environmental conditions. Electron microscopy an...
The utility of pheromone enhanced ant baits was investigated using fire ants as the model organism. The enhanced bait consisted of hydramethylnon (active ingredient), soybean oil (phagostimulant and Ai solvent), defatted corn grit (carrier), and 'invictolide', a component of the fire ant queen recog...
Three potential biological control organisms, a fungus Beauveria bassiana, a protozoan Thelohania solenopsis and a parasite, Solenopsis daguerrei are being evaluated in the field to suppress fire ant populations. All of these organisms have some detrimental effect on fire ants in the laboratory but ...
