Social insects nesting in soil environments are constant contact with entomopathogens but have evolved a range of defence mechanisms, resulting both individual and social immunity that reduce the chance for epizootics colony, as case subterranean termites. Coptotermes formosanus uses its faeces building material nest structure result into 'carton material', here, we report faecal supports growth Actinobacteria which provide another level protection to group against entomopathogens.

Illustrated identification keys are presented for soldiers and winged adults of the following 17 termite species known from Florida: Calcaritermes nearcticus Snyder, Neotermes castaneus (Burmeister), N. jouteli (Banks), luykxi Nickle Collins, Kalotermes approximatus Incisitermes milleri (Emerson), I. minor (Hagen), schwarzi snyderi (Light), Cryptotermes brevis (Walker), C. cavifrons Banks, Family Kalotermitidae; Coptotermes formosanus Shiraki, Reticulitermes flavipes (Kollar), R. hageni...

Foraging populations of colonies the eastern subterranean termite, Reticulitermes flavipes (Kollar), were surveyed in residential and undeveloped environments southeastern Florida. A triple mark-recapture program using dye marker Nile Blue indicated foraging R. contain ≍0.2–5.0 million termites per colony, territories encompass an area up to 2,361 m 2 a linear distance 71 m. Habitat type was not correlated with population size.

Laboratory techniques developed to evaluate insecticides for prevention or remedial control of infestations Coptotermes formosanus Shiraki showed that the evaluation could not be based on mortality alone. The behavioral responses termites had considered. can seal off avoid treated areas and effectively protect themselves. Factors causing this behavior appear repellency insecticide itself chemical factor (s) associated with dead termites. tested divided into three groups, depending reactions...

Over the past 50 years, repeated attempts have been made to develop biological control technologies for use against economically important species of subterranean termites, focusing primarily on entomopathogenic fungus Metarhizium anisopliae. However, no successful field implementation has reported. Most previous work conducted under assumption that environmental conditions within termite nests would favor growth and dispersion agents, resulting in an epizootic. Epizootics rely ability...

While hybridization of an invasive species with a native is common occurrence, between two rare. Formosan subterranean termites (Coptotermes formosanus) and Asian (C. gestroi) are both ecologically successful the most economically important termite pests in world. Both have spread throughout many areas world due to human activity; however, their distributions overlap only three narrow because distinct ecological requirements. In south Florida, where C. formosanus gestroi invasive, dispersal...

Two chitin synthesis inhibitors, hexaflumuron and diflubenzuron, were evaluated in a laboratory choice test for their potential as bait toxicants against the Formosan subterranean termite, Coptotermes formosanus Shiraki, eastern Reticulitermes flavipes (Kollar). Concentrations of that elicited feeding deterrence >125 ppm C. >62.5 R. flavipes, whereas concentrations required to cause >90% mortality at 9 wk > 15.6 >2 respectively. Diflubenzuron deterred such low (>2 ppm) highest recorded was...

Distance effects of three treatments, noviflumuron, fipronil, and thiamethoxam, against laboratory populations the Formosan subterranean termite, Coptotermes formosanus Shiraki, were tested in extended foraging arenas with distances 50 m. The results showed that during 10-wk test period, all termites killed by noviflumuron baits, whereas nonrepellent termiticides fipronil thiamethoxam divided into two groups after causing 25–35% worker mortality. horizontal transfer lethal was ≤5 For...

Abstract Effective entomological surveillance planning stresses a careful consideration of methodology, trapping technologies, and analysis techniques. Herein, the basic principles technological components arthropod plans are described, as promoted in symposium “Advancements monitoring technology, techniques, analysis” presented at 58th annual meeting Entomological Society America San Diego, CA. Interdisciplinary examples for urban, medical, veterinary applications reviewed. Arthropod...

Abstract The Formosan subterranean termite management initiative dubbed “Operation Full Stop”, sought to protect structures within New Orleans’ historic French Quarter. This program, lasting from 1998 2012, was able decrease the overall population of termites in area but did not eliminate all detectable colonies. Since Operation Stop ended there has been a significant number alates observed Quarter during reproductive flight season. Pedigree analysis conducted on trapped major swarm events...

Abstract While chitin synthesis inhibitor baits are environmentally friendly and sustainable measures to control subterranean termites compared conventional termiticides, the lengthy time required eliminate a termite colony is perceived as drawback for both homeowners pest industry. Recent efforts have focused on overcoming such problem by accelerating baiting process. To accelerate elimination, 20-hydroxyecdysone was proposed potential active ingredient due its similar mode of action...

Tunnel formation by Coptotermes formosanus and Reticulitermes flavipes was studied in a two-dimensional foraging arena with moisture gradient. Moisture did not appear to affect tunneling when termite first emerged from the central release chamber. But as termites of both species moved further away chamber into gradient, they tunneled significantly (P < 0.05) more sand higher content than lower content. Over 10 d test period, Fractal analysis indicated that regardless content, tunnel geometry...

During April 1996, we were informed by the Department of Agriculture and Consumer Services a possible new infestation Formosan subterranean termite, Coptotermes formosanus Shiraki, in commercial building at northwest corner Highway 1 State Road 836 Miami, Florida (Fig. 1). This infestation, which is 2 blocks west Port about 10 km south currently known distribution C. southeastern Florida, 1.5 site another introduced Heterotermes species (Scheffrahn & Su 1995). A large number alates swarmed...

A field study was conducted to examine the foraging pattern of Formosan subterranean termite, Coptotermes formosanus Shirah dye, Sudan Red 7B, used as a marking material identify foragers feeding at specific sites. The results showed that termites selected their sites random. No preferences in site were observed. Since random, all given colony would visit site, sufficient time. It is theoretically possible, therefore, introduce suitable control agent single and eliminate entire colony.

The entomopathogenic fungus Metarhizium anisopliae (Metsch.) Sorokin was tested in the laboratory against field-collected groups of eastern subterranean termite, Reticulitermes flavipes (Kollar) (Isoptera: Rhinotermitidae), foraging arenas to determine potential effect a "trap and treat" protocol (trapping part population, treating it with biological control agent releasing back into original population). Individual termites were treated suspension M. conidia released containing untreated...
