“…Mangosteen growers in Thailand do not consider fruit ßies as pests and do not apply pesticide sprays for their control. Burikam et al (1992) found no B. dorsalis or B. carambolae from laboratory inspection of 40,000 mangosteen fruit obtained from orchards around Thailand. Therefore, mangosteen may qualify as a natural nonhost or conditional nonhost (North American Plant Protection Organization [NAPPO] 2008), and, if so, the requirement for a quarantine treatment before export may be unnecessary.…”

Postharvest quarantine treatments (irradiation or vapor heat) are used to control fruit flies and other pests in mangosteen (Garcinia mangostana L) exported to the United States and Japan from Thailand. No-choice tests were conducted in the laboratory to determine whether Thai mangosteen is a host for Bactrocera dorsalis (Hendel) (oriental fruit fly) and Bactrocera carambolae Drew & Hancock (carambola fruit fly). Ripe commercial quality fruit (1 wk after harvest) that were either undamaged or damaged by puncturing or peeling the pericarp were exposed to a high density of gravid flies in screen cages and then held for 10 d and dissected to inspect for immature life stages. Undamaged mangosteen fruit were not infested by B. dorsalis and B. carambolae. Partially damaged fruit with shallow punctures in the pericarp that did not extend to the aril also were not infested. Both fruit flies could infest damaged fruit if the pericarp damage allowed oviposition in the aril. Results suggest that natural infestation of mangosteen by B. dorsalis and B. carambolae can only occur if fruit exhibit physical cracks or mechanical injury. Resistance appears to be due to the pericarp hardness and thickness as well as latex secretion. Nonhost status could be used without additional quarantine measures to achieve quarantine security against B. dorsalis and B. carambolae in mangosteen exported from Thailand.

“…To estimate parameters (β 1 , β 2 , and β 3 ), published data for lethal time (LT 100 ) of B. dorsalis were obtained (Burikam et al 1992). However, due to the lack of information, additional data was included from B. invadens (now considered to be the same species) (Grout et al 2011) and another species B. tryoni (De Lima et al 2007;Heather et al 1996;Jessup 1992;Jessup et al 1993;Jessup et al.…”

NeoBiota 27: 37-67. doi: 10.3897/neobiota.27.5177 Abstract This study introduces a simple generic model, the Generic Pest Forecast System (GPFS), for simulating the relative populations of non-indigenous arthropod pests in space and time. The model was designed to calculate the population index or relative population using hourly weather data as influenced by developmental rate, high and low temperature mortalities and wet soil moisture mortality. Each module contains biological parameters derived from controlled experiments. The hourly weather data used for the model inputs were obtained from the National Center of Environmental Prediction Climate Forecast System Reanalysis (NCEP-CFSR) at a 38 km spatial resolution. A combination of spatial and site-specific temporal data was used to validate the GPFS models. The oriental fruit fly, Bactrocera dorsalis (Hendel), was selected as a case study for this research because it is climatically driven and a major pest of fruit production. Results from the GPFS model were compared with field B. dorsalis survey data in three locations: 1) Bangalore, India; 2) Hawaii, USA; and 3) Wuhan, China. The GPFS captured the initial outbreaks and major population peaks of B. dorsalis reasonably well, although agreement varied between sites.

The site-specific temporal comparisons implied that the GPFS model is informative for prediction of relative abundance. Spatial results from the GPFS model were also compared with 161 published observations of B. dorsalis distribution, mostly from East Asia. Since parameters for pupal overwintering and survival were unknown from the literature, these were inferred from the distribution data. The study showed that GPFS has promise for estimating suitable areas for B. dorsalis establishment and potentially other non-indigenous pests. It is concluded that calibrating prediction models with both spatial and sitespecific temporal data may provide more robust and reliable results than validations with either data set alone.

Environment-friendly management of fruit flies involving pheromones is useful in reducing the undesirable pest populations responsible for decreasing the yield and the crop quality. A nanogel has been prepared from a pheromone, methyl eugenol (ME) using a low-molecular mass gelator. This was very stable at open ambient conditions and slowed down the evaporation of pheromone significantly. This enabled its easy handling and transportation without refrigeration, and reduction in the frequency of pheromone recharging in the orchard. Notably the involvement of the nano-gelled pheromone brought about an effective management of Bactrocera dorsalis, a prevalent harmful pest for a number of fruits including guava. Thus a simple, practical and low cost green chemical approach is developed that has a significant potential for crop protection, long lasting residual activity, excellent efficacy and favorable safety profiles. This makes the present invention well-suited for pest management in a variety of crops.
