Termites

Termites are social insects that are found occurring in many regions of the world as pests of agriculture and forests as well as forest products and buildings. They are covered in a range of CABI's products, depending on the emphasis required. For example, in soils, in field crops and grasslands, or in our forestry coverage - see TREE CABWeb®. On PEST CABWeb® we are making available a small sample of the abstracts from the Review of Agricultural Entomology, mainly on various methods of the control of termites.

AB Prey utilisation at low prey densities was determined for third instar Cueta sp., Furgella intermedia and Palpares annulatus larvae in terms of wet weight, dry weight, energy and nutrients. Prey utilisation was similar to other insects on a wet weight (42-47%), dry weight (46-49%), energetic (40-58%) and nutritive basis (62-79%). Lipids (33-36%) provided energetically the highest contribution of the nutrients ingested. The quantities of water, proteins, nucleic acids, lipids and carbohydrates extracted by the antlion larvae were in proportion to their availability in their prey, Hodotermes mossambicus larvae. The quantities of nutrients extracted by the antlion larvae at low prey densities were not significantly influenced by differences in mandible size, antlion body weight or the trapping method (building a pit or not) of the antlion species. It is proposed that a low metabolic rate and the accumulation of fat reserves, and not the extent of prey utilisation, enable P. annulatus larvae to tolerate a 123-day starvation period in which 22.3% of their body weight is lost.

AB An earlier survey of 17 800 boulevard and park trees in Toronto, Ontario, suggested that Reticulitermes flavipes selectively attacked or avoided different tree species. Solvent extractions were performed of the bark, sapwood, and heartwood of a tree species frequently infested by R. flavipes, Aesculus hippocastanum, and of a tree very rarely infested, Ailanthus altissima. When termites were forced to feed upon papers impregnated with 4% extracts, neither termite mortality nor relative amounts of feeding provided strong evidence of differential suitability of these trees as hosts for R. flavipes. However, in behavioural assays, a majority of the Aesculus hippocastanum extracts elicited positive termite orientation responses, while a majority of Ailanthus altissima extracts elicited negative responses. It is concluded that colonization of different tree species by R. flavipes can be correlated with the presence of behavioural chemicals.

AB Five samples of hinoki (Chamaecyparis obtusa) wood from both natural forests and plantations in Kochi Prefecture, Japan, were investigated with respect to their termiticidal activity against Coptotermes formosanus. Hinoki heartwood from natural forests had extremely high termiticidal activity. Quantitative experimental data showed that it had more than 170 times of the activity than heartwood from a plantation. This might provide a rationale for the chemical classification of commercial hinoki wood. A relatively large correlation was obtained between the activity against termites and the volatile extractive content, as well as a negative correlation with the average width of annual rings, suggesting that the growth rate correlates with the biosynthesis of termiticidally active substances. The difference in termiticidal activity among the tested heartwoods is considered to be determined mainly by difference in the volatile components.

AB Two baits, hydramethylnon and hexaflumuron, were evaluated for the control of subterranean termites (Macrotermes darwiniensis) in Texas in 1994-96. Hydramethylnon bait was tested for one year at four structures infested with subterranean termites. Control of termites was not achieved; however, colony suppression, as indicated by the number of wood stakes attacked by termites, may have occurred at two locations. Hexaflumuron bait was tested for two years at seven structures infested with subterranean termites. Control of termites occurred at one location where more than 17 Baitubes were consumed. Colony suppression, as indicated by the number of monitoring stations attacked by termites, appears to have occurred at two structures. With both hydramethylnon and hexaflumuron, lack of termite activity at bait stations might indicate a reduction in colony population size (or elimination); however, independent monitoring stations (wooden stakes and wood blocks) used during these tests indicated that termites were present even though termites were not detected in the bait stations.

AB Field trials of subterranean termite bait efficacy require interpretation of descriptive statistics more often than application of the scientific method. The cryptobiotic life history of subterranean termites, their loosely defined colony territories containing several loci of activity, and current research tools for their study often precludes definitive conclusions. Five locations with observed termite activity in and around structures in Georgia were included in baiting studies using a cellulose powder bait matrix with either abamectin or zinc borate hydrate against Reticulitermes spp. These experiments are described in the form of case studies. The data collected at two sites only involved observations of termite activity. At the other three sites, numbers of termites, wood consumption, and bait consumption were recorded from established termite monitors. Interpretation of the data collected varied in relation to the amount of information collected at each site and results ranged from complete reductions in termite activity following bait removal to bait removal followed by no indication of reductions in indices of termite activity. The problems associated with constructing a cause and effect relationship between bait applications and recorded changes in indices of termite activity are discussed. These include verification of colony associations, verification of bait consumption by one of several colonies within the baiting area, determination of colony movement or fractionating, and separation of normal variation in activity indices versus impact of bait removal.

AB The results of a 5 year study with 6 termiticides including: bifenthrin, chlorpyrifos, cypermethrin, fenvalerate, permethrin, and isofenphos indicate significant differences in effectiveness among products applied to different soil types in Texas. Each of the 5 field test locations represent very different soil types and environmental conditions. Termiticides were applied in 1990 with soil samples taken from the replicated treatment plots at 1 and 6 months, and then annually through 5 years. Soil residues of termiticides were measured with gas chromatography. The amount of pesticide remaining in each sampling period indicates a significant loss of termiticide by the fifth year of the test. The bioavailability of termiticide remaining in the soil was estimated through bioassays utilizing field collected subterranean termites (Reticulitermes flavipes). Both tunnelling distance and mortality were used as indicators of termiticide activity and availability. The results of the bioassays confirmed the findings of the residue analysis portion of the project. The most stable termiticides, through 5 years, were permethrin and fenvalerate. Isofenphos was the least stable with significant loss of activity within 24 months post-application. The most challenging conditions, in terms of effective termiticide residuals retained through time, were alkaline soils with high clay content and organic compositions greater than 1%. The most favourable soils were those that are acidic with low clay and organic content.

Heartwood of P. elliottii and P. caribaea was consistently less susceptible than that of P. radiata. The latter was similar to susceptible Araucaria cunninghamii sapwood. CCA (at 0.23% m/m Cu+Cr+As) or permethrin (at 0.024% m/m a.i.) treatment in sapwood reduced feeding on adjacent P. radiata heartwood, but boron (at 0.082% m/m B) did not have the same effect.

AB Etofenprox has relatively low mammalian toxicity. When applied topically to workers from several different colonies of Coptotermes formosanus, the LD50 of etofenprox of 4.8-6.6 was in the same general range as those of soil termiticides currently in use. Etofenprox was a relatively quick acting termiticide, with most mortality occurring within 24 h. In both vertical and horizontal laboratory tunnelling assays, etofenprox concentrations as low as 10 p.p.m. reduced termite penetration of crushed coral and silica sand, and consistent protection was achieved with concentrations of 100 p.p.m. or greater. Termites avoided contact with the treated substrate and mortality was generally low, indicating that most termites did not contact the substrate often or long enough to acquire a lethal dose. These results indicate that it may be useful both as a contact insecticide for injection into active termite infestations within structures, and as a soil insecticide to prevent termites from entering structures. It is concluded that 100 p.p.m. etofenprox in the soil is a reasonable minimum target concentration for field application.

AB The insect pathogenic hyphomycete fungus Metarhizium anisopliae is promising as a biological insecticide for many species of subterranean termites. In Australia, a survey of termite mounds and feeding sites using a selective medium showed that this fungus is widespread but rarely causes mortality of termites under natural conditions. One isolate, code-named FI610, has been selected for detailed field trials on the basis of its high virulence for a range of termite species and efficacy at high temperatures. Various options for using this fungus as a biological insecticide are now being evaluated in the field. Four are described. (1) Direct treatment of termite nests. As little as one gram of pure conidia may suffice for control depending on correct application of the formulation and the time of year in which it is carried out. Spores persist for at least two years in the nest. (2) Spraying directly onto and/or into timber structures to protect at least for a certain period against termite damage, relying on the repellency of the conidia to Australian species of termite. (3) Mixing of conidia into soil to create a barrier around timber structures. Depending on circumstances over two years' protection of timber has been achieved in SE Australia. (4) Use of the fungus as the controlling agent in bait systems. The major factor limiting the efficacy of M. anisopliae, especially in baiting systems, is the behavioural response of healthy termites to the applied fungal conidia, to foraging termites carrying conidia and to termites infected with the disease.

AB Dihydro-5,6-dehydrokawain was isolated by a simple method without chromatography from the leaves of Alpinia speciosa [A. zerumbet] (collected at Nishihara in Okinawa, Japan) and identified by instrumental analyses. 4-Hydroxy-6-(2-phenylethyl)-2H-pyran-2-one was prepared by hydrolysing dihydro-5,6-dehydrokawain, and 3 dihydro-5,6-dehydrokawain derivatives were synthesized by reacting this compound with phosphoric agents. Among the synthesized compounds, dimethyl [6-(2-phenylethyl)-2-oxo-2H-pyran-4-yl]phosphorothionate had the strongest antifungal activity of 91% at 100 ppm against Corticium rolfsii, compared with 64% growth inhibition for dihydro-5,6-dehydrokawain at 100 ppm. Dihydro-5,6-dehydrokawain showed poor insecticidal activity (<10% mortality at 1 mg/filter paper) against termites (Coptotermes formosanus), but greater activity was shown by some of the derivatives (93% for dimethyl [6-(2-phenylethyl)-2-oxo-2H-pyran-4-yl]phosphorothionate).

For the 2nd experiment, B. bassiana strain 447 formulations were prepared with rice substrate on which the fungus had been produced and/or harvested conidia. The formulation was applied to termite nests 0.3-1.6 m in height and termite mortality was visually evaluated after 100 days. In the 1st experiment, 100% mortality was observed in 19 of 20 nests treated with M. anisopliae and the remaining nest showed only <approx>30% survival. Nests treated with B. bassiana had 0 to 100% mortality. The best result was obtained with 6 g of a formulation containing 2g of conidia added to rice medium. High mortality was obtained in treatments using 12 g of formulation without conidia or with 1 g of conidia added to the rice medium. Application of 3g of conidia with no rice killed 2 of 4 nests, but the other 2 nests had no mortality.

AB Populations of 6 colonies of Coptotermes formosanus in Florida were significantly reduced but survived after 12 months of baiting using metabolic inhibitors such as A-9248 (diiodomethyl para-tolyl sulfone) or sulfluramid. These survived colonies recovered within several years and caused additional structural damage to the nearby buildings. Nine colonies (6 of C. formosanus and 3 of Reticulitermes flavipes) were eliminated after 2-9 months baiting using the chitin synthesis inhibitor hexaflumuron. Colony elimination generally created zones of termite-free soil that lasted for several years, except for one colony whose territory was invaded by a new C. formosanus colony 9 months after the baiting. The presence of neighbouring colony populations were evident in 3 sites but these neighbouring colonies did not take over territories of eliminated colonies. Two additional colonies (one each of R. flavipes and C. formosanus) were intentionally left alive after partial suppression using hexaflumuron baits. One colony (R. flavipes) slowly declined and eventually collapsed 4 years after the baiting, while the other colony (C. formosanus) recovered. The results of this study demonstrated the advantages of colony elimination in providing long-term protection of structures from subterranean termites. Elimination of colony populations was achieved only when hexaflumuron was used. Baits containing metabolic inhibitors such as A-9248 or sulfluramid only partially suppressed the colony populations even after the monthly placement of baits for 12 months. Elimination of the vast populations of subterranean termites requires that the toxicant must be slow-acting and non-deterrent, must not cause adverse effects when ingested at sublethal dose levels, and its lethal time must be dose-independent.
