“…Time mortality response of T. urticae to different fungal isolates @ 10 8 spores ml -1 conidia ml -1 for B. bassiana and M. anisopliae, respectively against T. urticae. The probit -values obtained in the present study are also in accordance withAlves et al (2002);Irigaray et al (2003);Draganova and Simova (2010) andSeiedy et al (2010) against T. urticae. Many isolates of Beauveria species have been found to produce toxic compounds after invasion of the host haemolymph…”

Background: Entomopathogenic fungi are microorganisms that specifically infect and often kill insects and other arthropods. Most are non-pathogenic to plants and relatively non-toxic to humans and animals. Use of fungal entomopathogens can be an alternative to insecticides and could help in bio-intensive pest management. The current study aimed to study the pathogenicity of entomopathogenic fungal isolates against two Spotted Spider Mites, Tetranychus urticae Koch in tomato and broad Mite, Polyphagotarsonemus latus (Banks) in chilli. Methods: An extensive survey for the natural occurrence of entomopathogenic fungi on insects and mites was made in different agro climatic regions of Tamil Nadu during 2013 and 2014. Survey revealed the occurrence of two entomopathogenic fungi viz., Beauveria bassiana (Balsamo) Vuillemin and Metarhizium flavoviride Gams and Rozsypal var. minus. Laboratory experiment was conducted to evaluate the pathogenicity of fourteen isolates of Beauveria bassiana, Metarhizium anisopliae and Lecanicillium lecanii against Tetranychus urticae and Polyphagotarsonemus latus. Result: In opposition to T. urticae, the Beauveria bassiana isolate Bb 112 showed the highest toxicity of all the other isolates tested, with low LC50 value of 0.6 x106 spores ml-1 and LT50 of 92.60h. Against P. latus, Bb 112 had high virulence with low LC50 value of 0.3x106 spores ml-1 and LT50 value of 92.32h. Hence, there is potential for use of entomopathogenic fungi in the field conditions as an alternate control method in combating the insect pests and other arthropod pests since they are considered natural mortality agents and are environmentally safe.

“…Vuill. seems to be a good candidate for controlling sucking pests, such as aphids, leafhoppers, whiteflies and mites (Hatting, Poprawski, and Miller 2000;Faria and Wraight 2001;Vandenberg et al 2001;Feng et al 2004;Wekesa, Knapp, Maniania, and Boga 2006;Maniania et al 2008;Bugeme, Maniania, Knapp, and Boga 2008;Seiedy, Saboori, Allahyari, Talaei-Hassanloui, and Tork 2010). Commercial products have been developed with this fungus with successful results (Faria and Wraight 2001).…”

Effects of the entomopathogenic fungus Beauveria bassiana were studied on life table parameters of two-spotted spider mite, Tetranychus urticae feeding on bean and cucumber under laboratory conditions. The developmental periods for all immature stages were not affected by fungal infection on each host plant but the duration of larval stage was significantly longer on bean. The female and male longevity, oviposition period and fecundity were significantly lower on fungustreated mites but were not different between two host plants. Significant reductions were found on the intrinsic rate of increase (r m ), the net reproductive rate (R 0 ), the finite rate of increase (l), the mean generation time (T c ) and the population doubling time (D t ) as a result of mycosis. Only the mean generation time (T c ) was influenced considering the effect of host plant, which was shorter on cucumber.

“…Periodic releases of lacewings appear to be effective against T. urticae and T. kanzawai , but have not been evaluated in cassava crops . Lastly, entomopathogens can inflict high mortality on mites, and have received some attention for control of M. tanajoa , T. kanzawai , T. urticae and T. cinnabarinus on various crops, including cassava …”

Cassava is a major staple, bio-energy and industrial crop in many parts of the developing world. In Southeast Asia, cassava is grown on >4 million ha by nearly 8 million (small-scale) farming households, under (climatic, biophysical) conditions that often prove unsuitable for many other crops. While SE Asian cassava has been virtually free of phytosanitary constraints for most of its history, a complex of invasive arthropod pests and plant diseases has recently come to affect local crops. We describe results from a region-wide monitoring effort in the 2014 dry season, covering 429 fields across five countries. We present geographic distribution and field-level incidence of the most prominent pest and disease invaders, introduce readily-available management options and research needs. Monitoring work reveals that several exotic mealybug and (red) mite species have effectively colonised SE Asia's main cassava-growing areas, occurring in respectively 70% and 54% of fields, at average field-level incidence of 27 ± 2% and 16 ± 2%. Cassava witches broom (CWB), a systemic phytoplasma disease, was reported from 64% of plots, at incidence levels of 32 ± 2%. Although all main pests and diseases are non-natives, we hypothesise that accelerating intensification of cropping systems, increased climate change and variability, and deficient crop husbandry are aggravating both organism activity and crop susceptibility. Future efforts need to consolidate local capacity to tackle current (and future) pest invaders, boost detection capacity, devise locally-appropriate integrated pest management (IPM) tactics, and transfer key concepts and technologies to SE Asia's cassava growers. Urgent action is needed to mobilise regional as well as international scientific support, to effectively tackle this phytosanitary emergency and thus safeguard the sustainability and profitability of one of Asia's key agricultural commodities. © 2016 Society of Chemical Industry.
