“…Therefore, the timing of when females drop oV their host onto fungi-contaminate d soil, and the point at which egg laying is reduced, may be of critical importance in terms of reducing the tick population . The time interval between tick inoculatio n and death and the dose which caused the high mortality were similar to those of many susceptible insects, that are known as natural hosts for M. anisopliae (Liu et al, 1989, Butt et al, 1992, Rath et al, 1995.…”

The pathogenicit y of Wve species of entomopathogeni c fungi (Deuteromycetes, species: Beauveria bassiana, Metarhizium anisoplia e, Metarhizium¯avovirid e, Paecilomyces fumosoroseus and Verticillium lecanii) to the various developmental stages of Boophilus annulatu s ticks was compared under laboratory conditions. M. anisoplia e and B. bassiana strains were most virulent to engorged females and caused 85 ± 100% mortality within 7± 10 days post-inoculatio n (PI). The highest mortality of engorged females caused by other fungi reached only 25 ± 60%. All tested fungi prevented or reduced the egg laying capability of the ticks several days before their death. Females surviving after treatment with the most virulent M. anisoplia e strain (Ma-7) reached only 7± 8% of their egg laying capacity as compared with the control. Other fungi caused a reduction of the weight of laid eggs by 35.4 ± 80.8% as compared with untreated females. Only M. anisoplia e and B. bassiana strains caused 70± 98% mortality of the treated eggs. Unfed larvae of Boophilus annulatu s were sensitive to M. anisoplia e and M.¯avovirid e strains. The Ma-7 strain was most virulent to unfed larvae, with a mortality rate of 80.4% at a concentration of 1 3 10 7 spores ml 2 1 and 100% mortality at a concentration of 1 3 10 8 spores ml 2 1 .

“…These results were further substantiated by the chi-square value, which clearly indicated that the model Þts the probit analysis. According to Liu et al (1989), Puterka et al (1994), and Jones et al (1996), the virulence of any fungal isolate to cause mortality in insects is directly related to the spore concentration. Our data follow a similar pattern, in which mortality increased from 31.3 to 76.5%, translating to a 40% increase in mortality for a 10-fold increase in spore concentration.…”

“…Each of the isolates differs signiÞ-cantly in its pathogenicity against a target species; therefore, a potential pathogen must be evaluated individually against a target insect pest (Zimmermann 1993). Different strains of M. anisopliae have been used for controlling many agriculturally important insect pests such as beetles (Liu et al 1989, Moorhouse et al 1993, aphids (Milner and Soper 1981), planthoppers (Samuels et al 1989), and pear psylla (Puterka et al 1994). The use of this fungus as a potential control agent in the household environment also was evaluated against termites (Kramm et al 1982) and ants (Kelley-Tunis et al 1995).…”

Problem statement: Coptotermes curvignathus (Isoptera: Rhinotermitidae) is a common termite pest found in oil palm plantation planted on peat. Currently, the control methods focus on using insecticides that lead to high cost and adverse effect to the environment. Approach: Biological control like the use of entomopathogens provides an alternative control method for termite infestation problem. However, several factors need to be investigated in order to obtain a virulent strain with potential to be developed into a biopesticide. Results: Three local isolates (MG, LR2 and TA) of Metarhizium anisopliae were obtained and identified as M. anisopliae var. anisopliae using molecular techniques. Growth performance of isolates on four basal media namely, Potato Dextrose Agar (PDA), Potato Dextrose Agar with 1% yeast extract (PDAY), Sabaroud Dextrose Agar (SDA) and Sabaroud Dextrose Agar with 1% yeast extract (SDAY) was assessed. The pathogenicity of each isolate was tested against subterranean termite Coptotermes curvignathus at three concentrations of 1×10 6 , 1×10 7 and 1×10 8 conidia mL −1 . Infections of the isolates were examined using electron microscopy technique. The growth performance of each isolate differed significantly. Among all basal media, only SDAY was able to produce high growth performance and thick conidia mats with all isolates. The most pathogenic isolate was LR2, which caused 100% mortality at 1×10 7 conidia mL −1 within 3 days post-inoculation. Conclusion/Recommendations: All three isolates were pathogenic against C. curvignathus as they were able to germinate and penetrate into the termite cuticle within 15 hours post-inoculation. The three local isolates of M. anisopliae var. anisopliae have potential to be developed as biopesticides to control termites, C. curvignathus in oil palm plantations.
