Identification : ARZT-1361350-H31-151

Durée : Jul 1, 2009 à Sep 30, 2013

Domaine : termites ; foraging termite populations ; termite monitors

Partenaire : UNIVERSITY OF ARIZONA 888 N EUCLID AVE TUCSON,AZ 85719-4824

Objectifs
1) The evaluation of commercial monitoring stations alone with several novel designs to compare capture efficiency with regards to termites with implications for termite baiting and research studies. 2) Developing a new methodology for delineating the foraging territories of H. aureus colonies using an animal protein marking technique.

Descriptif
Procedure 1 : A randomized complete block designed grid with 10 replications of the initial commercially and novel stations representing eight treatments will be established. Evaluations will be taken on three separate dates starting in the fall. Treatment 1- Arizona Research Monitoring Station (ARMS)-ASH consisted of 15.8-cm long x 15.8-cm diameter PVC pipe. Within each station/collar were placed a section of rolled cardboard (B flute) with a piece of ash (Fraxinus sp.) was in the center with the cardboard wrapped around the wood. A 16-cm x 16-cm x 1.5-cm concrete brick paver will be placed on top to secure it. Treatment 2- ARMS- with PINE southern yellow pine (Pinus spp.) Treatment 3 -ARMS-BLANK BAIT TUBE of Sentricon with no AI. A 7.6-cm hole will be dug in the middle of the collar to accommodate the bait tube. Treatment 4-CARDBOARD ONLY of a 10-cm x 120-cm section of rolled cardboard (B flute) that will be wrapped in 6.7-cm duck tape. Treatment 5 CARDBOARD ONLY ASH consisting of rolled cardboard (B flute)that will be wrapped in tape. A piece of 2.5-cm x 1.5-cm x 10-cm ash (Fraxinus sp.) will be positioned in the center and forced 2 mm into the soil. Treatment 6 will be FirstLine Termite Defense System which is manufactured by FMC ; Treatment 7 Termicon Termite Interceptor Station by Pestube Systems and Treatment 8 the Termitrol Bait System. Procedure 2 : The field study again will be conducted on H. aureus colonies located at the Santa Rita Experimental Range, Pima Co., Arizona. We will establish six field circular grid plots in which we will collect monthly samples. Each collection station consists of three cardboard wood-centered rolls placed within a piece of 0.15-m dia. X 0.15-m long PVC pipe capped with a concrete brick. The grid will consist of 50 additional collecting stations set out along the circumference of five annuli. The annuli are centered on the original active collecting station with radii of 1.5, 2.0, 4.0, 7.0 and 10.0 m. Termite populations will be sampled every 30 days for several months by removing one of the three cardboard rolls containing termites from each station occupied by termites, we can proceed with the treatment. A subsample of at least five termites will be placed in 100% EHOL for DNA analysis at a later date for confirmation of core colony determination. In the fall, one cardboard roll in the center collecting station of the grid will be replaced with a rabbit IgG marked roll. Termites in the center collecting station of the grid will be allowed to feed on the roll for minimum of 30 days. At which time, the grid will again be sampled by collecting one cardboard roll and return them to the lab for processing. All six plots will be subject to an ELISA marking technique. Data collected, along with possible DNA analysis, will be used to determine the colony size and foraging area of each colony within the plot.
