The Role of parasitoid in controlling the population of fruit flies (Bactrocera dorsalis Complex.) (Diptera: Tephritidae) who attacked mangoes (Mangifera indica L) in Buleleng Regency. Thisresearch was conducted with the aim of knowing the role of parasitoids in controlling the population of fruit flies (Bactrocera dorsalis Complex.) (Diptera: Tephritidae) on mango plants (Mangifera indica L.) in Buleleng Regency. Field research was carried out at the Buleleng mango plantations while laboratory research was carried out at the Integrated Pest Management and Plant Disease Laboratory from April to July 2019.Field research was carried out at  the Buleleng mango plantations while laboratory research was carried out at the Integrated Pest Management laboratory and  was  carried out  from  April  to  July 2019.  Determination of the location of sampling  is  done  diagonally  and  fruits  infested  larvae  was  taken  purposively. The results showed that there were three species of fruit flies that attacked mango in Buleleng Regency, namely B. carambolae, B. papayae and B. occipitalis with an abundance of B. carambolae 39.3%, B. papayae 64.4% and B. occipitalis 0.3% and found three types of parasitoids namely Fopius sp, Diachasmimorpha sp. and Opius sp. The role of parasitoids in controlling fruit flies is still low when viewed from the parasitization rate of the three parasitoids namely Fopius sp. (2,24%), Diachasmimorpha sp. (1,9%), and Opius sp. (0,46%).

Water analyses from six commercial tomato packinghouse dump tanks in South Carolina revealed that metal and pesticide residues accumulate in the dump-tank water during daily operation. The amount that accumulated varied widely as follows: Asana (esfenvalerate), 0.3 to 13.8 ppb; Bravo (chlorothalonil), 0.1 to 2.7 ppm; copper, 2.0 to 7.3 ppm; and manganese, 0.1 to 2.5 ppm. Contamination appeared to be lowest when growers implemented integrated pest management (IPM) during production. In a subsequent controlled study, tomatoes were produced under the following pest-management practices: IPM protocol with pesticide applications based on scouting reports, modified IPM with one arbitrary pesticide application at bloom, and weekly pesticide application regardless of pest pressure. In a small-scale dump tank simulating commercial packinghouse operation, the water used for tomatoes that were produced with a weekly spray schedule had about 2 to 10 times the amount of pesticide and metal residues found in the water used for tomatoes grown under IPM protocol. Modified IPM protocol resulted in intermediate levels of residues. These results confirm that IPM field practices can reduce residues in tomato packinghouse wastewater.
