The Royal Palm, Roystonia regia (Kunth) O. F. Cook, is a quintessential tree in South Florida landscapes and has relatively few pests. However, it can be severely damaged by non-predictable population flare-ups of the Royal Palm Bug (RPB), Xylastodoris luteolus Barber. Damage appears as frizzled new growth that reduces aesthetics ...

The stink bug, Oebalus insularis (Stal), was first observed in Florida rice fields in 2007. An extensive survey was conducted during 2008 and 2009 to determine the relative abundance and population biology of O. insularis in Florida rice fields. It occurred in 100% of all fields sampled and constituted 20% ...

Temperature-based development models have been used in pest management for many years to predict emergence and other life history events of insect pests. Blueberry gall midge, Dasineura oxycoccana (Johnson), is an early-season pest of rabbiteye blueberries, Vaccinium virgatum Aiton, in Florida. The ability to predict emergence of adults at the ...

Fruits from 6 exotic, cultivated fruit species were collected in the Tafi and Calchaqui valleys between Jan 2000 and Jan 2002 to determine the occurrence of Ceratitis capitata (Wiedemann) and Anastrepha fraterculus (Wiedemann) and the corresponding fruit infestation levels. The valleys are situated in the western semiarid highlands of Tucuman ...

Camponotus vittatus Forel is a poorly studied Neotropical ant, which is very common in Brazil. Larval descriptions are useful to systematics, as larval characters aid with genus-level differentiation, and ant larvae lie at the basis of ant social organization. This study presents the first description of the immatures of C. ...

We conducted 2 studies on nectar-feeding by MacNeill's sootywing, Hesperopsis gracielae (MacNeill), a rare skipper, near the lower Colorado River in Cibola Valley, Arizona. In the first study, we examined rates of visitation by adults to Heliotropium curassavicum (Boraginaceae) inflorescences and Sesuvium verrucosum (Aizoaceae) flowers on potted plants. Visitation rates ...

The fall armyworm Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) is a pest of most turfgrass species in the United States. Twelve cultivars and genotypes of zoysiagrass (Zoysia spp.) were evaluated for resistance to both neonate and 4-d-old fall armyworm larvae. Three cultivars, 'Cavalier', 'Emerald', and 'Belair', were the most ...

The synchronous firefly Photinus carolinus (Green) of the moist cove hardwood forests of the Great Smoky Mountains National Park attracts much public attention during its spectacular month-long mating display known as The Light Show. In previous studies flash synchrony among P. carolinus males has been investigated, but little is known ...

Bemisia tabaci (Gennadius) is an important agricultural pest worldwide. The pest is a species complex composed of numerous biotypes, among which biotypes B and Q are the 2 most invasive and widely distributed. Our previous study found that the ratio of the biotype Q has been increasing and displacement of ...

The picture-winged fly Euxesta stigmatias Loew (Diptera: Ulidiidae) has been a serious pest of sweet corn in Florida since the 1930s and had been considered the only fly infesting Florida corn. In a sweet corn variety trial to evaluate E. stigmatias resistance in 2007, adult Chaetopsis massyla (Walker) (Diptera: Ulidiidae) ...

Laboratory experiments were designed to identify the host strain paternity of fall armyworm Spodoptera frugiperda (J. E. Smith) mated females. In no-choice tests, corn or rice strain females were placed in cages with males of the opposite strain. After 48 h, females were dissected and spermatophores were removed. Molecular markers ...

Lesser cornstalk borer (LCB), Elasmopalpus lignosellus (Zeller), is a serious pest of bean (Phaseolus vulgaris L.) and many other crops. The effect of mulching as a management method for LCB was examined in 2 field experiments conducted in small plots (1 m2) at 2 different locations (experiments A and B) ...

An artificial larval diet for Anastrepha striata (Schiner) was developed and the changes in the rearing and quality parameters through 6 generations during the adaptation were characterized. In the first experiment we tested diet formulations that had already been developed for the mass-rearing of Anastrepha ludens (Loew), A. obliqua (Macquart), ...

Neochetina eichhorniae Warner and N. bruchi Hustache, biological control agents of Eichhornia crassipes (Martius) Solms-Laubach, are usually incapable of flight but occasionally develop indirect flight muscles enabling dispersal. This reportedly alternates with oogenesis and is reversible. We examined host quality as a possible explanation for the transitions between these 2 ...

Survival of Diaprepes root weevil Diaprepes abbreviatus (L.) (Coleoptera: Curculionidae) larvae was assessed in flooded marl soil and a flooded nursery potting medium with green buttonwood (Conocarpus erectus L., Combretaceae) as a food source for the larvae. Root-zone flooding may be a viable control option for flood-tolerant ornamental plants including ...

Evidence of a sex pheromone released by sapodilla bud borer, Zamagiria dixolophella Dyar (Lepidoptera: Pyralidae), females was obtained under field conditions. Delta type traps baited with 2-d-old virgin females captured wild males in a sapodilla (Manilkara zapota (L.) van Royen) plantation. Once the existence of the sex pheromone was demonstrated, ...

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 ...
