Chemical control of the mealybug Pseudococcus longispinus (Targioni-Tozzetti) was most effective if sprays were applied when the mealybugs were in the dispersive crawler stage and when the host plant afforded the least shelter. A two-spray program with sprays applied in August and late November effectively controlled a dense infestation of the mealybug on citrus. Red scale (Aonidiella aurantii (Maskell)), the major insect pest of citrus, was also effectively controlled. An overall pest management program has been developed for citrus in which all insect pests are controlled by combination of natural enemies and insecticides as required. Outbreaks of the mealybug, and other secondary pests, are controlled by sprays of aminocarb or methomyl. These two insecticides prevented the population resurgence of mealybugs in the subsequent generation which occurred when maldison was used. Bioassays showed that aminocarb and methomyl were toxic for less than a week to the mealybug and to parasites and predators, whereas maldison and methidathion were toxic to the parasites and predators for about a month. Parasite pupae inside the host mealybug survived sprays of maldison and aminocarb. It is suggested that natural enemies emerging after spraying, from resistant or protected stages, survive sprays of aminocarb and methomyl but not sprays of more persistent insecticides like maldison; and that these survivors continue to suppress populations of their hosts. Hence aminocarb and methomyl are probably specific in their action against the mealybug and the other secondary pests of citrus because of their short persistence.An insecticide check experiment failed to demonstrate that natural enemies significantly reduce populations of the mealybug. Possible reasons for the failure are discussed.

Monitoring of warehouse inventory data processing is an important thing for companies. PT Talaga mulya indah is still manual using paper media, causing problems that have an effect on existing information, namely: problems with data processing of incoming and outgoing goods. And the difference between data on the amount of stock of goods available with physical data, often occurs inputting data more than once for the same item, searching for available data, and making reports so that it impedes companies in monitoring inventory of existing stock of goods. Which aims to create a system that can provide updated information to facilitate the warehouse admin in making inventory reports, and reduce errors in input by means of integrated control. In this study, the authors used the data collection method used in this analysis using the method of observation, interviews, and literature review (literature study). For analysis using the PIECES analysis method. Furthermore, the system design used is UML (Unified Modeling Language). The results of this study are expected to produce the right data in the process of monitoring inventory data processing, also can provide the right information and make it easier to control the overall availability of goods.

Rinamba opacicollis Cameron (Hymenoptera: Braconidae) was collected from Chikkamagaluru, Karnataka, India for the first time from the larvae of white stem borer, Xylotrechus quadripes Chevrolat infesting arabica coffee. Its role in the biological or integrated control of X. quadripes remains to be evaluated. White stem borer could be the first host record of this parasitoid all over the world.
