Survey and Ecological Studies of the Termites (Isoptera: Kalotermitidae) of Mona Island

URL: http://www.fcla.edu/FlaEnt/fe78p305.html
shown in filters: Publications A survey of eight sites on Mona Island revealed four termite species in the family Kalotermitidae: Incisitermes nr. bequaerti (Snyder), I. nr. incisus (Silvestri), Neotermes mona (Banks), and Procryptotermes
corniceps (Snyder). Incisitermes nr. bequaerti is a new record for the island. Identifiable wood hosts are reported. All species were found in dead wood, which is typical of drywood termites, but N. mona and P.
corniceps were also collected from live wood. Examination of dead wood in three 9.3 m2 plots in a dense stand of Leucaena leucocephala (Lam.) de Wit. revealed that an average of approximately three-quarters
of the wood pieces were attacked by termites. Although the total volume of dead wood was almost six times greater in Plot 1 than in the other two plots, the number of termites per unit volume of dead wood was
very similar (0.4 per cm3). Total numbers of individuals per colony ranged from 11 to 3,359 termites. Caste composition is reported for each colony, and large variations among colonies were noted. Alates as well
as eggs were more common in larger colonies. Soldier percentages ranged from 0.7% to 20.5% in 16 P. corniceps colonies. The largest colonies occurred when the greatest volume of dead wood was available.

COLONY FOUNDATION BY THE DRYWOOD TERMITE, CRYPTOTERMES BREVIS (ISOPTERA: KALOTERMITIDAE), AND THE PREVENTION AND REMEDIAL CONTROL OF DRYWOOD TERMITES WITH SELECTED CHEMICAL TREATMENTS

Treatments to prevent the establishment of Cryptotermes brevis drywood termite colonies were studied. Trap-blocks treated with disodium octaborate tetrahydrate (DOT) and
chromium copper arsenate prevented colony establishment. Moreover, surface treatments of DOT were deterrent to reproductive termites. Fewer termite colonies were initiated when
wood was treated with Drione. Termites avoided areas treated or adjacent to areas treated with DOT dust. Treatment by a single-point gallery injection of active colonies of this
termite species and Incisitermes snyderi indicated that spinosad killed 92-100 percent of the termites. DOT applications caused some mortality in treated boards. Greater mortality
occurred in DOT treated boards with Incisitermes snyderi. [ eng ] |
