“…At present, H. picea can be largely controlled by chemical insecticides; however, this method of control is not adequate (Osakabe and Kodomari, 1984;Hiromori et al, 2004;Yaginuma et al, 2004b). Many alternative agents such as entomopathogenic fungi and nematodes have been explored (Ishikawa, 2001;Hiromori et al, 2004;Yaginuma et al, 2004a, b).…”

“…Many alternative agents such as entomopathogenic fungi and nematodes have been explored (Ishikawa, 2001;Hiromori et al, 2004;Yaginuma et al, 2004a, b). In particular, the entomopathogenic fungus B. amorpha (Strain: HpBa-1) was reported as an effective agent against H. picea larvae, but this fungus is not in practical use (Yaginuma et al, 2004b). If HpBa-1 is practically used as a controlling agent for H. picea larvae, effective control may be achieved (Yaginuma et al, 2004b).…”

“…Currently, chemical insecticides such as fenitrothion are being used to control H. picea larvae (Shizuoka Plant Protection Office, 2003). However, it is difficult to control H. picea larvae with fenitrothion (Osakabe and Kodomari, 1984;Hiromori et al, 2004;Yaginuma et al, 2004b). Young larvae (first to second stage), which are susceptible to fenitrothion, inhabit the deep soil.…”

“…Therefore, it is thought that using HpBa-1 at this period is a suitable way to control H. picea larvae. Temperatures in November are relatively low for fungal infection in tea field soil (around 15°C), but this strain has the ability to grow and infect under these temperatures (Yaginuma et al, 2004b). Yaginuma et al (2004b) demonstrated the potential for using HpBa-1 as a control agent against H. picea larvae.…”

A strain of Beauveria brongniartii PBbr-1 was isolated from infected larvae of Heptophylla picea. This isolated strain attained 100% mortality of H. picea adults at a concentration of 1.0ϫ10 7 conidia/ml, with a short median lethal time of 8.4 d for females and 7.0 d for males. The number of eggs laid by adults and percent of eggs hatching for females inoculated with PBbr-1 were lower than those by healthy females. However, when PBbr-1 was inoculated directly to the eggs, hatchability was almost the same as that in non-inoculated eggs. Since infected females appeared to lay eggs just before death, the eggs from females infected with PBbr-1 were thought to be unfertilized. Furthermore, PBbr-1 showed a high virulence to the first-stage larvae. PBbr-1 not only had a high virulence to the adults, but also suppressed subsequent generations. PBbr-1 is thus thought to be a very effective control agent for H. picea in combination with Beauveria amorpha HpBa-1.

Sustainable tea cultivation will rely increasingly on alternatives to conventional chemical insecticides for pest management that are environment-friendly and reduce the amount of pesticide residues in made tea. Entomopathogens can provide effective control, conserve biodiversity, and serve as alternatives to chemical insecticides under several conditions. Due to their specificity for insects, these pathogens including viruses, bacteria, and fungi are ideal candidates for incorporation in the integrated pest management strategies for tea where their effects on other natural enemies will be minimal. Biological and ecological characteristics of several dominant natural entomopathogenic microorganisms have been well documented throughout the tea-growing countries particularly China, Japan, and India. But research to convert them to microbial insecticide formulations for tea pest control by evolving suitable techniques for production, standardization, formulation, and application has not progressed well except in Japan and China to some extent. Increased use of microbial control will depend on a variety of factors including improvements in the pathogens' virulence, formulation, delivery, etc. and an increased awareness of their attributes by growers and the general public. In this review, we provide an overview of microbial control of the key insect pests of tea and also the scope for future studies for their better utilization.
