They rely mostly on the entozoic fauna for the digestion of cellulosic materials. The present study is based upon the diversity of flagellates protists isolated from the gut of a lower termite, Heterotermes indicola, belonging to three genera i.e. Holomastigotes (H. campanula, H. annandalei and H. metchnikowi), Holomastigotoides (H. hemigynum, H. hartmanni, H. kempi, H. koidzumi and H. metchnikowi) and Pseudotrichonympha (P. grassii). The largest and most abundant species Pseudotrichonympha grassii was identified by molecular studies using the SSU rRNA gene, confirmed by phylogenetic analysis and compared with that of the P. grassii isolates reported from other parts of the world. The results showed that the P. grassii observed in our study was phylogenetically most closely related to the Japanese P. grassii isolate. The biodiversity of the entozoic flagellates is important in targeting for biological control of termites as well as for isolation and culturing of flagellates to produce cellulases, an important industrial enzyme.

  • Effect of Increased Soil Moisture and Reduced Soil Temperature on a Desert Soil Arthropod Community
    Effect of Increased Soil Moisture and Reduced Soil Temperature on a Desert Soil Arthropod Community WILLIAM P. MACKAY, SOLANGE SILVA, DAVID C. LIGHTFOOT, MARIA INEZ PAGANI and WALTER G. WHITFORD' Department of Biology, Box 3AFJ New Mexico State University, Las Cruces 88003 ABSTRACT: The effects of soil moisture and temperature on arthropod communi- ties were experimentally examined in the northern Chihuahuan Desert of New Mex- ico. Shaded plots were established which lowered the soil temperature several degrees; some plots received artificial rainfall to increase soil moisture. Shading reduced soil temperature at 5-cm depth 7-10 C. Soil moisture at 5 cm accounted for most of the variation in surface activity of subterranean termites (r values between 0.3 and 0.7). Termites did not respond to temperature differences. When all soils were at field capacity, there was no difference in termite activity in shaded and unshaded plots. There were higher densities of mi- croarthropods in litter bags on the shaded plots than on the unshaded plots. Numbers of microarthropods were an order of magnitude larger in litter bags on watered and shaded plots than on other plots. Lower litter temperatures apparently affect litter ar- thropods more than increased soil moisture. Shade had no effect on ant colonies but there were fewer colonies on the watered plots. There was between 40 to 50% mass loss from creosotebush leaf litter after 7 months on all plots. Water and soil temperature had no effect on decomposition rates. INTRODUCTION Temperature extremes and water availability are considered to be the most impor- tant factors limiting production, activity of desert organisms and ecosystem processes in deserts (Noy-Meir, 1973, 1974; Whitford et al., 1981, Whitford et al., 1983).

  • Toxicity Potential of the Heartwood Extractives from Two Mulberry Species Against Heteroternes Indicola
    ISSN impresa 0717-3644 Maderas. Ciencia y tecnología 21(2): 153 - 162, 2019 ISSN online 0718-221X DOI: 10.4067/S0718-221X2019005000203 TOXICITY POTENTIAL OF HEARTWOOD EXTRACTIVES FROM TWO MULBERRY SPECIES AGAINST Heterotermes Indicola Babar Hassan1,♠, Sohail Ahmed1, Nasir Mehmood1, Mark E Mankowski2, Muhammad Misbah-ul-Haq3 ABSTRACT Choice and no-choice tests were run to evaluate natural resistance of the woods of two Morus species (Morus alba and Morus nigra) against the subterranean, Heterotermes indicola, under field conditions. Tox- icity, antifeedant and repellency potential of the heartwood extractives was also investigated under laboratory conditions. Heartwood extractives were removed from wood shavings by using methanol or an ethanol: tolu- ene (2:1) mixture. Results of choice and no-choice tests with sap and heartwood blocks exposed to termites, showed that both mulberry species were resistant to termites but in comparison, Morus alba wood was more resistant than Morus nigra to termite feeding as it showed <5 % weight loss after 90 days. Termites exhibited a concentration dependent mortality after exposure to either mulberry species’ heartwood extractives. The high- est termite mortality occurred after termites were exposed to filter paper treated withMorus alba extractives at a concentration of 5 %. At this concentration, antifeedancy and repellency were calculated to be 91,67 and 84 % respectively. Our results also showed that extractives from either mulberry species imparted resistance to vacuum-pressure treated non-durable Populus deltoides wood. Termite mortality was greater than 75 % after feeding on Populus deltoides wood treated with extractives from Morus alba. Solvent only (methanol) treated Populus deltoides controls, showed a minimum weight loss of 2,69 % after 28 days.

Egyptian Journal of Biological Pest Control (2018) 28:86 Egyptian Journal of https://doi.org/10.1186/s41938-018-0092-6 Biological Pest Control RESEARCH Open Access Potential of bacterial chitinolytic, Stenotrophomonas maltophilia, in biological control of termites Faiza Jabeen1*, Ali Hussain2, Maleeha Manzoor1, Tahira Younis1, Azhar Rasul1 and Javed Iqbal Qazi3 Abstract Termites are important pest of crops, trees, and household wooden installments. Two species Coptotermes heimi and Heterotermes indicola are the major species of termites that results in great economic loss in Asia including Pakistan. Chitinases have drawn interest because of their relevance as biological control of pests. The study was performed to screen chitinolytic bacteria from dead termites and to determine their chitinolytic activity in degrading chitin content of termites. Ten isolates were obtained forming clear zones on chitin-containing agar plates. One isolate (JF66) had the highest (3.3 mm) chitinolytic index. Based on sequence of 16S rRNA gene, the isolate was identified as Stenotrophomonas maltophilia with (99%) similarity under Accession number KC849451 (JF66), and DNA G + C content was found to be (54.17%). S. maltophilia (JF66) produces chitinases upto 1757.41 U/ ml at 30 °C and pH 6.0 employing diammonium phosphate as a nitrogen source. Chitinase gene was also extracted and gets sequenced that confirmed its presence. Whole culture and different concentrations of crude enzyme of the isolate were tested on the chitin covering of termites. Mortalities showed that crude enzyme of isolate could degrade chitin of both species of the termites C. heimi and H. indicola. Chitinase produced by S.

  • Appraisal of the Economic Activities of Termites: a Review
    Bajopas Volume 5 Number 1 June, 2012 http://dx.doi.org/10.4314/bajopas.v5i1.16 Bayero Journal of Pure and Applied Sciences, 5(1): 84 – 89 Received: October 2011 Accepted: April 2012 ISSN 2006 – 6996 APPRAISAL OF THE ECONOMIC ACTIVITIES OF TERMITES: A REVIEW *Ibrahim, B. U. and Adebote, D. A. Department of Biological Sciences, Faculty of Science, Ahmadu Bello University, Zaria, kaduna state *Correspondence author: [email protected] ABSTRACT Termites can be found through out the world largely in the tropical and sub-tropical countries. They are social insects, feeding on cellulosic materials and live in colonies. Termites comprise the Order Isoptera with six families, 170 genera and 2600 species, of which six species are present in Nigeria. The most striking aspects of termites is their destructive tendency. They feed on wood indiscriminately, and tend to destroy timber and other wooden materials of importance to man, and this brought them into direct competition with man. However, their beneficial aspect to man is very significant. In most countries, where termites exist in abundance they are edible. Their burrowing within the soil increases the rate of percolation of water into the soil, thereby promoting water absorbent of the soil. Their feeding habit includes decomposition of dead trees, and incorporation into the soil, mineral nutrients of these trees. Man in response to the destructive activities of termites, developed various controlled methods towards them, which include the use of pesticides such as DDT ( Dichloro Diphenyl Trichloroethane), BHC ( Benzene Hexachloride ), Aldrin, Dieldrin, soil barrier termiticides, treated zone termiticides, dust and fumigant, and, non chemical control methods such as mud tube removal, debris removal, pathogenic fungi, mechanical barriers, heat, high voltage electricity or electrocution and wood replacement.

  • Effect of Different Insecticides Against Termites, Heterotermes Indicola L
    EFFECT OF DIFFERENT INSECTICIDES AGAINST TERMITES, HETEROTERMES INDICOLA L. (ISOPTERA: TERMITIDAE) AS SLOW ACTING TOXICANTS AHMAD-UR-RAHMAN SALJOQI1*, NOOR MUHAMMAD1, IMTIAZ ALI KHAN2, SADUR-REHMAN3, MUHAMMAD NADEEM2and MUHAMMAD SALIM1 1Department of Plant Protection, The University of Agriculture, Peshawar-Pakistan 2Department of Entomology, The University of Agriculture, Peshawar-Pakistan 3Agriculture Research Institute, Tarnab, Peshawar, Pakistan. *Corresponding author: [email protected] ABSTRACT Three insecticides viz Regent, Tracer and Match were evaluated as slow toxicants against subterranean termites, Heterotermes indicola L (Isoptera:Termitidae). The experiment was performed using termite workers of H. indicola to which these insecticides were dipped in blotting paper once only, in start with the following concentration i.e. 0.000312, 0.000156, 0.00078, 0.00039 and 0.000195%. The total mean percent of mortality after ten days results concluded that Regent (Fipronil 5% SC) was 91.79, 86.40, 78.94, 74.18 and 62.06%, while Tracer (Spinosad 240 SC) was 72.60, 63.53, 60.60, 59.06 and 28.60%, and finally Match (Lufenuron 5% EC) was 49.40, 31.06, 26.19, 22.18 and 10.66%, repectively. Maximum mortality and avoidance was obtained by toxicity of Regent, as it was capable of obtaining 100% mortality even before day ten on every concentration therefore, Regent was considered highly toxic. Tracer was found to be slow acting agent. 100% mortality was recorded by using the 1st concentration of Tracer on day 7, on day 9 by using the 2nd concentration, while on day 10 by using the 3rd concentration of Regent. Match was unable to cause 100% mortality by using any of the tested concentrations.
