Wolbachia is a ubiquitous endosymbiotic bacterium that manipulates insect reproduction. A notable feature of Wolbachia is male killing (MK), whereby sons of infected females are killed during development; however, the evolutionary processes by which Wolbachia acquired the MK ability remain unclear. The tea tortrix moth Homona magnanima (Tortricidae) harbours three non-MK Wolbachia strains (wHm-a, wHm-b and wHm-c) and an MK strain wHm-t.

This study was conducted to provide complete information about the symptoms, incidence and severity, whitefly biotypes, as well as the dominance status of the three species in pepper-producing areas in Java. A DNA analysis was carried out on leaf samples to identify species and biotypes of collected from 18 areas (16 districts) in lowlands (<400 m asl) and highlands (>700 m asl).

Developing olfaction-based control methods was urges as an alternative to commonly used but non-environmental friendly chemical pesticides. However, the molecular mechanisms underlying TMB reception mechanism are still lacking.
