“…On the other hand, Salvato et al (2002), using AFLP and mtDNA markers (COI and COII), found that in the winter pine processionary moth, Thaumetopoea pityocampa (Lepidoptera: Thaumetopoeidae), in Mediterranean regions, the mtDNA marker showed a higher level of genetic differentiation than the AFLP, suggesting that males appear to disperse more extensively than females. Contrary to previous studies, Shapiro et al (2008) found that Conopomorpha cramerella (Lepidoptera: Gracillariidae) located throughout the Malay Archipelago showed a low level of genetic variation both from COI and elongation factor-1a (EF-1a), suggesting no obvious gender-biased migration in the species. Considering these examples, it seems difficult to make a general conclusion based on genderbiased dispersal in insects, particularly in lepidopteran species.…”

In an effort to gain greater insight into the nature of the population genetic structure of the pest insect Spodoptera litura (Lepidoptera: Noctuidae), tobacco cutworms were collected from six Korean and five Chinese localities, and their mitochondrial A+T-rich region and nuclear internal transcribed spacer 2 (ITS2) were cloned and sequenced. The A+T-rich region and nuclear ITS2 provided a maximum sequence divergence of 2.88 and 1.82%, respectively. Overall, a low level of genetic fixation (F(ST) = 0-0.02965 in the A+T-rich region and 0-0.34491 in ITS2) and no discernible isolated population were noted among most S. litura populations. Along with these results, the absence of genetic variance between Korea and China indicates a profound interrelation of the S. litura populations in the two countries, consistent with the current notion that S. litura has sufficient flight capacity for dispersal.

“…In West and Central Africa Cocoa Swollen Shoot Virus, which has been spread to cacao from local forest trees, has long been a destructive pathogen and the indigenous oomycete Phytophthora megakarya causes up to 100 % crop loss through pod rot (Bowers et al 2001;Tondje et al 2007). In Southeast Asia, where Indonesia is the world's 3rd largest producer of cacao (Shapiro et al 2008;ICCO 2010), the main constraints to cacao production are Black Pod and Stem Canker caused by P. palmivora, pod damage caused by the indigenous cocoa pod borer moth, Conopomorpha cramerella Snellen (Wardojo 1980;Lim 1992;Shapiro et al 2008), and Vascular Streak Dieback (VSD), caused by Oncobasidium theobromae (Talbot & Keane 1971;Keane & Prior 1991).…”

“…The severity of the infestation of the pest in cocoa production centers on CPB in Sulawesi region reached 39%-79% [2]. If there are no control measures, it is estimated that over the next 7-10 years, the Indonesian cocoa farm acreage will be throughoutly infested by CPB with a high severity [4]. Therefore, the success of the pest control will directly support the sustainability of cocoa production in Indonesia.…”

Cocoa pod borer (CPB) has endangered Indonesian cocoa. Use of entomopathogen in biocontrol of pests is considered to be environmentally friendly approach. Verticillium tricorpus has been reported to be a potential agent for controlling CPB. The aim of this research was to study the possibility in using alternative, easy and cheap media and also the role of intensity and quality of light for mass production of V. tricorpus. The experiments were laid out in split-plot design as factorial, where every combination treatment was replicated three times. Medium, in form of semi-synthetic and natural, was treated as the main plot, while light as sub-plot. Results of this study showed that for the growth and development of fungus V. tricorpus, the use of alternative natural media in form of a mixture of cocoa pod husk and maize was the best. Use of cocoa dextrose agar (CDA) as semi-synthetic medium was more suitable for the growth and development of V. tricorpus compared to potato dextrose agar (PDA). The semi-synthetic and natural media consisted of cocoa husk and maize are suitable for cocoa production area in Indonesia, where mostly cocoa is planted in lowland area and mostly is also suitable for corn but not for potato growing. Growth of the fungus colony especially on CDA medium reached its optimum condition when using white light with the intensity of 1,000 lux. This study proved that the requirement for light quality was different between growth and development purposes. Development of V. tricorpus until the production of conidia in optimal condition was reached with the use of yellow light with the intensity of 1,000 lux.
