Spodoptera litura is the main pest in soybean plants and can cause up to 50% damage and often results in decreased productivity and even crop failure. Spodoptera litura is widespread in areas with hot and humid climates from the subtropics to the tropics. S. litura pests attack cultivation plants in the vegetative and generative phases. The prospect of insect pathogens as a substitute for chemical insecticides is quite good in terms of their effectiveness and impact on the environment. Nuclear Polyhedrosis Virus (NPV) is one of the Baculoviridae viruses that infect the larval stage. Spodoptera litura Nuclear Polyhedrosis Virus (SlNPV) is a pathogenic virus that infects armyworms. SlNPV JTM 97C is an effective isolate in controlling larvae of Spodoptera litura. The larvae used in this study were larval instar 4, instar 5, and instar 6. The study was conducted using a Completely Randomized Design (CRD) with 6 treatments and 3 replications. The treatments consisted of controls, 1 g / l, 2g / l, 3 g / l, 4 g / l, and 5 g / l. Each treatment was applied to instar 4, instar 5 and 6 instar larvae. The results showed that SlNPV JTM 97C affected mortality, stopped eating and pupa formation of instar 4, instar 5 larvae, but did not affect instar 6 larvae. The younger the larval instar the higher the pathogenicity response.","PeriodicalId":393541,"journal":{"name":"Jurnal Pengendalian Hayati","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129085914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rhizobacteria sampling was taken from rice fields in Mayang District. Weed sampling technique is done by purposive randomized sampling. The collections of pathogen-infected weeds are then isolated using laminar airflow and identified through several test stages. DRB exploration results obtained by two microorganisms that can be used as biological control to control the main weeds of rice plants from the Pseudomonas group, they are P. syringae pv. glycinea (M1) and P. syringae pv. syringae (M2). Based on the identification of the two isolates morphologically that (M1) has a greenish-white color with a flat edge type. Whereas the isolate code (M2) has a yellowish murky white color with a rather irregular jagged edge type. However, the two isolates have similarities in spherical shape. The physiological observations of both M1 and M2 isolate from the Catalase test, fluorescent pigments produce gram-positive (+) while gram tests produce gram-negative (-).

This study used a Randomized Block Design (RBD) with six treatment, namely: P1 = polyculture of shallot + Lemongrass; P2 = polyculture of shallot + celery; P3 = Polyculture of shallot + mustard; P4 = Polyculture of shallot + Lemongrass + mustard; P5 = Polyculture of shallot + celery + mustard; P6 = Monoculture of shallot. Each treatment was repeated 4 times. Observation started at 30 days after planting. Data collection was done by observing directly on the sample plants. Sampling was carried out using Yellow trap and pit fall trap. Samples were taken at each plot 10 times with intervals of 4 days. Observations included collecting the pest insects and natural enemies that were found, counting the number of populations in each species, scoring towards the damage plants. The results showed that shallot planting by polyculture with different types of plants affected the population of pests and natural enemies as well as the level of diversity of insects in shallots. Planting shallots by polyculture has been proven to control pest populations compared to planting shallots by monoculture. Polyculture planting with two types of plants proved to be better than polyculture planting with three types of plants where the best treatment was found in P1, namely polyculture of shallot and lemongrass with the smallest pest population which was 17.5.","PeriodicalId":393541,"journal":{"name":"Jurnal Pengendalian Hayati","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128417204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research was conducted by knowing the level of pathogenicity of Aschersonia sp. in C. pseudomagnoliarium pests based on observations of C. pseudomagnoliarium nymph mortality variables, mycosis, mummification, and LC50 values (Lethal Concentration 50) and LT50 (Lethal Time 50). This research can provide information on the pathogenicity of Aschersonia sp. against C. pseudomagnoliarium in citrus plants. The highest percentage of mortality occurred at the treatment density of 109 spores/ml with a value of 77.50% and the lowest percentage of mortality occurred at the treatment density of 105 spores/ml with a value of 15.00%. LC values indicate that the spores density of 2.8 × 107 spores/ml has been able to kill 50% of the test insects, while to kill 90% of the test insects requires a density of 2.4 × 1010 spores/ml and to kill 95% of the test insects requires a density 1.6 × 1011 spores/ml.
