  • This invention further relates to a method of substantially eradicating termites in an area comprising placing in the area at least one hermetically sealed station of the type referred to above.
  • One alternative to conventional soil treatment is the use of slow-acting bait to control populations of subterranean termites.
  • the monitoring/baiting program incorporating an insect growth regulator, hexaflumuron, as described by Su, N.-Y., Field Evaluation of a Hexaflumuron Bait for Population Suppression of Subterranean Termites (Isoptera: Rhinotermitidae), Journal of Economic Entomology 87: 389-397 (1994) is now commercially marketed as the Sentricon® Termite Colony Elimination System.
  • the monitoring/baiting program relies on routine monitoring to protect a given area.
  • a key component of the Sentricon system is the monitoring step.
  • An example is found in EP 0 283 142 Al, which teaches a monitoring apparatus that includes a plurality of detectors distributed over an area, each detector linked to an indicator that sends signals to the detectors and each detector responds only if it has detected a pest. Responders then permit the indicators to check on whether or not the links between the indicator and the detectors are intact. This system is not, however, specific to termites, and false positive results can occur.

  • an optical sensor is employed to detect termite movement in a pre- drilled foraging tunnel in a wood block.
  • the presence of subterranean termites is usually associated with elevated moisture (Su & Scheffrahn 1991, IRG ⁇ VP/1504).
  • U.S. Pat. Nos. 4,812,741 (Stowell et al, March 14, 1989) and 5,126,679 (Spry, June 30, 1992) teach the use of a moisture sensor to signal the presence of termites.
  • termites are known to produce gases such as CO and methane.
  • Such gases can be detected in the ground by use of subterranean probes (U.S. Pat. No. 3,943,750; McLaughlin et al, March 16, 1976).
  • subterranean probes U.S. Pat. No. 3,943,750; McLaughlin et al, March 16, 1976.
  • moisture or subterranean gases such as leaky plumbing, rainfall, putrefaction or fungal decay. Because these conditions are not unique to termite activity, monitoring stations adapted with these sensors or probes can cause false alarms and account for frequent, costly, and unnecessary on-site inspections.
  • microenvironment differences can signal a false positive response with this type of system.
  • the presence of other soil dwelling insects such as earthworms, ants, and beetle larvae also produce termite-presence conditions such as high humidity and gases. Again, because such conditions are not unique to termite activity, invasion by these soil dwelling insects will cause false positives and costly, unnecessary on-site inspections.
  • U.S. Patent No. 5,575,105 discloses a cellulose-based member with a plurality of holes transversely extending through it, each hole provided with an infrared emitting element that detects the presence of termites by an obstruction of an output wave caused by termites invading the holes. A detection signal is then generated to cause alarm lights to light up. The approximate number of termites can also be determined by counting the occurrences of the obstruction of output waves. The invasion of the holes by other insects and the presence of certain environmental conditions again renders this method susceptible to false positive responses. Another method of termite monitoring focuses on detecting termite feeding by vibrations or sound transmitted through wood when termites tear and break wood fibers (U.S. Pat. No.
  • acoustic emission devices can be useful as hand-held tools to detect activities of termites and other wood destroying insects in structures (Scheffrahn et al. 1997, J. Econ. Entomol. 90: 492-502). Because 30-40 monitoring stations are needed to protect a house for a monitoring/baiting program, however, it is cost-inhibitory to utilize such acoustic emission devices (generally > $1,000 per unit) in all of the stations. It is therefore highly desirable to incorporate a facile, inexpensive and specific termite- detecting sensor within the modern monitoring/baiting programs.
  • PCT Publication No. WO 93/23998 discloses a simple efficient sensor that utilizes a thin strip of conductive soft metal (i.e. aluminum foil) placed over wooden blocks or stakes.
  • a silver particle circuit placed over a wooden stake using a conductive pen is used as a sensor.
  • the wooden stake is typically used as a monitoring device for the Sentricon system.
  • the sensor is useful in detecting termites because the circuit is readily broken by termite feeding when it is placed in areas with termite activity. Thus, it is successful in the detection of true positive responses.

  • U.S. Patent 5,937,571 discloses a tamper resistant bait station containing cellulose baits.
  • the station has a plurality of apertures to allow termite access to a cellulose bait impregnated with a slow-acting toxicant. Because the cellulose baits are placed in soil and exposed to outdoor elements (rainfall, temperature fluctuation, high humidity, and biotic factors such as fungal decay and damage by other insects) through the housing apertures, the baits degrade rapidly and necessitate frequent onsite inspection and replacement of these cellulose baits.
  • These systems are intended for both remedial and preventative control and rely on a routine monitoring program to apply baits or to detect termites so that toxic baits can be applied.
  • An above-ground station made of a re-closable plastic bag containing bait matrix as described by Su et al (1997, J. Econ. Entomol. 90: 809-817) has an opening for termite access to the baits and is placed directly over active infestations of subterranean termites in a house or tree to allow an immediate bait consumption by termites.

  • the housing has a plurality of apertures that allows termites immediate access to baits, and multiple stations can be stacked on top of each other to provide termites with continuous access to bait material.
  • baits are provided for immediate consumption by termites for these above-ground systems, a periodical inspection is needed to determine whether bait replacement is necessary; this requires onsite visits by technicians to inspect these systems. Moreover, as with the in-ground system used in the monitoring-baiting program, baits for remedial control are applied only when termites are present.
  • This invention provides bait that is hermetically sealed with a non-biodegradable material, and further includes an electrically conductive material, preferably an electrically conductive non-metallic material, such as an electrically conductive material containing carbon, each of which can be tunneled or chewed through by termites. Because the bait is hermetically sealed in a weather-resistant enclosure, it remains intact in the environment for an extended period (i.e. years) until termite feeding occurs. For convenience, this novel bait including the electrically conductive material is referred to as the monitoring/hermetically sealed (HS) bait.
  • the monitoring/HS bait of the present invention can be used with or without monitoring; i.e.
  • monitoring/HS bait of the instant invention can also be distributed in a large quantity throughout, for example, an agricultural field.
  • the present invention provides a hermetically sealed bait package composed of a consumable material that is resistant to environmental degradation.

  • the subject invention is enclosed in a durable, sturdy station housing with termite-access holes to protect, from physical breakage, any soft and/or flexible material present in the monitoring/HS bait.
  • the present invention further provides a non-invasive means of determining whether termite feeding has occurred by receiving input from the electrical bridging circuit, thus eliminating the need to open the termite station. This increases operator efficiency and minimizes disturbance of the termites within the station thereby reducing the risk of abandonment of the station.
  • the present invention also provides for a termite bait station in which monitoring, baiting and recruiting of termites occurs within the same delivery system. This reduces manual labor and improves the efficiency in the termite colony elimination process.

  • HS baits containing toxin-containing cellulose baits similar to Fig. 1A are placed in the soil for 12 months to test their durability. The test is conducted in soil under outdoor conditions in south Florida. There is no known termite activity in the soil for the test site. Ten wooden stakes are planted in the soil as a comparison. After 12 months of exposure, HS baits are cut open to examine the status of termite baits. In all cases, the cellulose baits remain dry and intact (Fig. 3), while wooden stakes are badly decayed by fungi and in some cases damaged by wood destroying beetles. Soil dwelling organisms such as earthworms are also found in wet and badly decayed stakes. The results demonstrate that the closed-cell polyethylene wrapping provided protection of cellulose baits against environmental factors such as rainfall, high humidity, temperature fluctuation, and other biotic factors such as fungal decay, soil dwelling organisms or wood destroying beetles.
  • Wooden stakes (1" x 1.5" x 12") are placed in the soil in the backyard of a residential home to detect termite activity. After survey stakes are infested by termites, underground monitoring stations similar to that described by Su & Scheffrahn, Sociobiology 12: 299-304 (1986) are installed. Termite activity is found in two monitoring stations. Subsequently, more stations are installed over a period of time, but in all cases termites do not return to the stations once they are opened for inspection. Similar observations are made in the infested wood in the house and in other wooden stakes in soil (i.e. termites do not return to the locations when they are disturbed). The results agree with previous experiences with some infestations of R. virginicus.
  • HS baits in the configuration of Fig. 1C are placed vertically in the soil (Fig. 2A) surrounding the house, and are not disturbed for ten months.
  • the cellulose bait matrix is similar to that used in the Sentricon® system and contains 0.5% hexaflumuron.
  • Termite activity is observed in the house and mulch piles next to the house two months after initial placement of the HS baits, but by the fourth month, no termite activity has been detected in any of the survey stakes, the monitoring stations, the house or the landscape surrounding the house. After termite activity has been absent from the site for over seven months, the eight HS baits are removed from the soil for inspection, and evidence of termite feeding is observed in two HS baits (Fig. 4A).
  • termites collected from the five monitoring stations contain abnormally high proportions of secondary reproductives; an indication of population disruption by hexaflumuron. Also, the termites collected died shortly thereafter when kept under laboratory conditions; another indication that the population had consumed and are affected by hexaflumuron.
  • termites are collected from one station, with the other four stations not showing any sign of termite activity, i.e. no termite activity or termite feeding.
  • 46 are secondary reproductives; and the 33 workers exhibit signs of hexaflumuron effects such as sluggish movements and marble coloration. No termite activity is found in any of the monitoring stations five months after the installation of the 25 HS baits (Fig. 5).
  • HS baits Of these 25 HS baits, two are consumed by termites (Fig. 4A), and 23 are untouched (Fig. 4B). As with Example 1, the cellulose bait in the 23 untouched HS baits remain dry and intact. Because termite consumption of the baits occurred sometime between this five month period after installation of the HS baits, and no termite activity has been detected since that time, it is concluded that the R. flavipes population that had been infesting the house in question is eliminated.
