Abstract

Tribolium castaneum is primary pest in flour commodities and becomes a secondary pest in rice dan cereals. The damage caused by this pest attack is in the form of decreasing the quality and quantity of flour. One of the measure control of T. castaneum is fumigation using fosfin (PH3). This study aims to determine the percentage of mortality and find out the percentage of pupae become imago to the treatment of various doses and fumigation duration. The methode used is Completely Randomized Design (CRD) with 12 treatments and, 1 control and 3 replications. The variables observed included the mortality of larvae and imago, the number of pupae which turn into imago as well. The results of the observed variables were analyzed using variance and using the DMRT follow-up test with a level of 5%. The results of this study indicate that the use of phosphine fumigation is effective for controlling the pest of T. castaneum. The effective dose for controlling T. castaneum in this study was at a dose of 1g /m3 with a 12-hour exposure period and reduce the percentage of pupae which turn into imago by 0%.

Abstract

Golden apple snails (Pomacea canaliculata L.) is one of important pests in rice cultivation that could making damage up to 90%. Some attempt to control that often done among them is mechanical control and chemical control by using molluscicide. One of type of molluscicide that is have predominence to control golden apple snail is molluscicide with active ingredient of niclosamide with character contact pesticide. The purpose of this research to know the effectivity of molluscicide niclosamide to control golden apple snail pest by treatment of various concentration. This research was conducted in the Lampeji Village, Jember using Completely Randomized Design with 6 treatment and 4 replication with concentration of molluscicide each of which is 0 ml/l, 1 ml/l, 2 ml/l, 3 ml/l, 4 ml/l, and 5 ml/l. The observed variables is mortality of golden apple snail, crops damage intensity, and total eggs group produced by golden apple snail. The result show that treatments of molluscicide with active ingredient of niclosamide could control golden apple snail with value 61,75% until 89,06%. The effective and efficient treatment is application treatment with value of concentration is 3ml/l with value 84,68%. Application of molluscicide with active ingredient of niclosamide also affected in crops damage intensity. The result of crops damage intensity is coming up with score from 8,28% until 23,03%.  Treatments of molluscicide with active ingredient of niclosamide overall could reduce potention of spawn eggs from golden apple snail pest. Eggs only found in control found 1 to 3 eggs group, whereas in P1-P5 no.
