Callosobruchus maculatus F. (Coleoptera: Bruchidae) one of the main pests that cause damage to mung beans in storage areas. This research was conducted to determine the effective dose from soursop seed (Annona muricata) powder resulting mortality and emphasizing the amount of imago on the first-generation C. Maculatus. This research was conducted at Plant Pest Laboratory, Department of Plant Pests and diseases, Faculty of Agriculture, Universitas Padjadjaran, Jatinangor using experimental method of Complete Random Design (CRD) with 6 treatments and 5 replications. The treatments were tested using 5 doses of A. muricata seed powder with 1 grams, 3 grams, 5 grams, 7 grams, and 9 grams doses, and added with control or without treatment. The results showed that the dose of 5 grams A. muricata seed powder showed the mortality of C. maculatus  by 94% at 8 days after infestation, emphasizing the amount of eggs which is placed  C. maculatus of mungbean seed 77,64%. Emphasis on the emergence of the first generation of imago in the mung bean seeds is 74.67%. The lowest of loss weight mung beed seed amount 1,33%.Keywords: Annona muricata, Callosobruchus maculatus, Soursop Seed Powder, Mortality

The research aim wants to know: (1) Lethal Concentration (LC90) leaves fraction of Annona muricata, Annona squamosal, and Annona reticulate that caused death of third instar larvae of Aedes aegypti and Culex quinguefasciatus. The experimental method was used in research with completely random design. Each concentration was replicated five times. After introducing bioassay was done, five concentration used at real bioassay. For knowing LC90 from leaves fraction of Annona muricata, Annona squamosa and Annona reticulata, the data was analyzed by probit analysis. The result from this research showed that LC90 of leaves fraction methanol of leaves fration methanol was the highest of Annona squamosa (404 ppm) and the lower LC90 was leaves fraction n.heksa Annona reticulata (1894 ppm).

Plant Area

Weed is a part of OPT (Plant Disturbing Organism) besides plant pests and diseases. Weeds cause damage slowly, due to competition with cultivated plants to obtain nutrients, water, light, CO2 and growing space. Weeds are harmful and disturbing so humans try to control them. From various aspects of life both health, aesthetics, environment and the field of farming, weeds can interfere with natural habitat and beauty. Weeds are always considered as exotic plants or migrants that are invasive and potentially disrupt the local environment. However, not all weeds play a negative and potentially disturbing role. Weeds are also able to provide a comfortable habitat for the development of natural enemies in the agrosecosystem. Refugia is a weed plant area that can provide shelter, food sources or other resources for natural enemies such as predators and parasitoid. Efforts to conserve natural enemies using refugia are one alternative to controlling plant pest organisms such as pests. Keywords: Refugia, Weeds, Conservation, Natural Enemies

The Impact

Plant pests and diseases impact both food security and natural ecosystems, and the impact has been accelerated in recent years due to several confounding factors. The globalisation of trade has moved pests out of natural ranges, creating damaging epidemics in new regions. Climate change has extended the range of pests and the pathogens they vector. Resistance to agrochemicals has made pathogens, pests, and weeds more difficult to control. Early detection is critical to achieve effective control, both from a biosecurity as well as an endemic pest perspective. Molecular diagnostics has revolutionised our ability to identify pests and diseases over the past two decades, but more recent technological innovations are enabling us to achieve better pest surveillance. In this review, we will explore the different technologies that are enabling this advancing capability and discuss the drivers that will shape its future deployment.

Vegetation diversity and intensity of plant pests and diseases in two polyculture systems in Tanggamus District. The vegetable crop management cannot be separated from infestation of plant pest and disease which influences the quality and quantity of crop yield. The pest organism development is influenced by agroecosystem. The objective of this research was to analyze vegetation diversity and intensity of pest and disease in Tanggamus District. Methods used in this research were analysis of vegetation diversity based on Shannon index, percentage of pests damage and diseases incidence. The results showed that the vegetation diversity in polyculture of agriculture typology were 11 plant species with diversity index of 0.64; while in polyculture of agroforestry typology there were 11 plant species with diversity index of 0.74 and both of these indices were less than 1 (H’ < 1). The percentage of pests damage in the polyculture of agriculture larger than polyculture of agroforestry typology ranging from 7.20% to 81.67% and 3.04% to 26.67% respectively. While the incidence of disease in polyculture of agriculture ranging from 0.65% up to 100% and polyculture of agroforestry typology 0.65% up to 68.00%.

Trees provide key ecosystem services, but the health and sustainability of these plants is under increasing biotic and abiotic threat, including from the growing incidences of non-native invasive plant pests (including pathogens). The island of Ireland (Ireland and Northern Ireland) is generally accepted to have a high plant health status, in part due to its island status and because of the national and international regulations aimed at protecting plant health. To establish a baseline of the current pest threats to tree health for the island of Ireland, the literature and unpublished sources were reviewed to produce a dataset of pests of trees on the island of Ireland. The dataset contains 396 records of pests of trees on the island of Ireland, the majority of pests being arthropods and fungi, and indicating potentially more than 44 non-native pest introductions. The reliability of many (378) of the records was judged to be high, therefore the dataset provides a robust assessment of the state of pests of trees recorded on the island of Ireland. We analyse this dataset and review the history of plant pest invasions, including (i) discussion on notable native and non-native pests of trees, (ii) pest interceptions at borders and (iii) pests and climate change. The dataset establishes an important baseline for the knowledge of plant pests on the island of Ireland, and will be a valuable resource for future plant health research and policy making.
