Rodent species have been known as the major pest in the agricultural sector leading to economic losses. They are also identified as the vector for several rodent -borne zoonotic diseases. However, a specific study on observing their diversity in households closed to lowland irrigated agroecosystems that correspond to disease distribution’s role is limited. To address this issue, a field study was performed during the 2019 -2020 cropping season in two sites (Yogyakarta and West Java) which were categorized as the rice production centers. Trapping was conducted consecutively for 13-30 days using 65-75 snap traps. Roasted coconut and salty fish were used to attract rodents. In West Java, 3 rodent species ( Rattus argentiventer, Rattus tanezumi, Bandicota indica) and insectivore small mammal (Suncus murinus) were discovered from 1,950 trap nights. Meanwhile, the setting of 900 trap nights in Yogyakarta indicated less diverse rodents with only one species (Rattus tanezumi) and the same insectivore discovered. All captured animals were dissected and observed for the endoparasites. We obtained two potent species of parasites ( Taenia taeniaeformis and Capillaria hepatica), which can be transmitted by rodents to the local people if they do not apply a proper health practice.

Isolation And Characterization

Streptococcosis is one of bacterial diseases in the culture of Tilapia, Oreochromis niloticus and has caused significant economic losses. Streptococcus iniae, is known as pathogen to marine and freshwater fishes whereas Streptococcus agalactiae is known as pathogen to Tilapia. The isolation and characterization of four isolates of S. agalactiae, were described from an infected Tilapia from Cirata Reservoir, West Java, in July 2008. Conventional and rapid identification systems were used to determine isolates of S. agalactiae from brain and kidney tissues. In this paper, we have characterized S. agalactiae and this was the first isolation of this bacteria from fish. The isolates were gram positive, catalase-negative, oxidase-negative,  haemolytic cocci colonies on blood agar. All of the of isolates were biochemically characterized with the API 20 Strep System (bioMerieux). Bacterial chromosomal DNA used in PCR assay was extracted by heating method. The forward primer is Sdi 61: 5’-AGGAAACCTGCCATTTGCG-3’ and the reverse primer is Sdi 252: 5’-CAATCTATTTCTAGATCGTGG-3’ with gene target 16S intergenic spacer and it has 192 bp in length. These primers were designed by Alpha DNA (Montreal, Quebec). The biochemical patterns of four isolates were rather different although almost all traits were similar with the exception of pyroglutamic acid (pyra) and L-arginin (ADH), for which we observed negative and positive reaction in this study. Therefore, some of the biochemical characteristics of the four isolates did not fit 100% with the typical patterns of S. agalactiae. However, the PCR result showed that this PCR assay is an effective tool for rapid and specific detection of S. agalactiae, the main pathogens involved in warm-water streptococcosis, obtained from pure culture of naturally infected fish. Therefore, it could be a useful alternative for culture-based routine diagnosis of warm-water streptococcal infections in fish.

The American Elm (Ulmus americana L.) has been plagued by Dutch Elm Disease (DED), a lethal disease caused by the fungus Ceratocystis ulmi (Buisman) c. Moreau. Since its initial appearance in North America around 1930, DED has wrought inexorable devastation on the American elm population, triggering both environmental and economic losses. In response to the havoc caused by the disease, many attempts have been made to hybridize U. americana with a few ornamentally less desirable, though highly DED resistant, Asian species (mainly the Siberian elm, Ulmus pumila L., and the Chinese elm Ulmus parvifolia Jacq.). The goal is to develop, through breeding efforts, hybrid progeny that display the ornamentally desirable characteristics of U. americana with the disease resistance of the Asian species. Unfortunately, however, all attempts to hybridize U. americana have been prevented by incompatibility. Only through a firm understanding of both compatibility and incompatibility will it be possible to circumvent the incompatibility and hence achieve hybridization.

False spider mites are serious pests of pomegranate and frequently cause considerable economic losses in other fruit crops as well. A field experiment conducted to evaluate eleven acaricides against Tenuipalpus aboharensis infesting pomegranate plants, revealed that wettable sulphur at 2.5 g and dicofol at 2.5 ml per litre were very effective and other acaricides viz. propargite, fenpyroximate, chlorfenapyr and buprofezin were also found effective against T. aboharensis.

Virulence Gene Expression

Luminescent Vibrio harveyi is common in sea and estuarine waters. It produces several virulence factors and negatively affects larval penaeid shrimp in hatcheries, resulting in severe economic losses to shrimp aquaculture. Although V. harveyi is an important pathogen of shrimp, its pathogenicity mechanisms have yet to be completely elucidated. In the present study, isolates of V. harveyi were isolated and characterized from diseased Penaeus monodon postlarvae from hatcheries in Kerala, India, from September to December 2016. All 23 tested isolates were positive for lipase, phospholipase, caseinase, gelatinase and chitinase activity, and 3 of the isolates (MFB32, MFB71 and MFB68) showed potential for significant biofilm formation. Based on the presence of virulence genes, the isolates of V. harveyi were grouped into 6 genotypes, predominated by vhpA+ flaB+ ser+ vhh1- luxR+ vopD- vcrD+ vscN-. One isolate from each genotype was randomly selected for in vivo virulence experiments, and the LD50 ranged from 1.7 ± 0.5 × 103 to 4.1 ± 0.1 × 105 CFU ml-1. The expression of genes during the infection in postlarvae was high in 2 of the isolates (MFB12 and MFB32), consistent with the result of the challenge test. However, in MFB19, even though all genes tested were present, their expression level was very low and likely contributed to its lack of virulence. Because of the significant variation in gene expression, the presence of virulence genes alone cannot be used as a marker for pathogenicity of V. harveyi.

Over two million tonnes of fertiliser are applied to New Zealand pastures and crops annually and there is an increasing desire by farmers to ensure that the best possible economic return is gained from this investment. Spreading distribution measurements undertaken by Lincoln Ventures Ltd (LVL) have identified large variations in the evenness of fertiliser application by spreading machines which could lead to a failure to achieve optimum potential in some crop yields and to significant associated economic losses. To quantify these losses, a study was undertaken to calculate the effect of uneven fertiliser application on crop yield. From LVL's spreader database, spread patterns from many machines were categorised by spread pattern type and by coefficient of variation (CV). These patterns were then used to calculate yield losses when they were combined with the response data from five representative cropping and pastoral situations. Nitrogen fertiliser on ryegrass seed crops shows significant production losses at a spread pattern CV between 30% and 40%. For P and S on pasture, the cumulative effect of uneven spreading accrues, until there is significant economic loss occurring by year 3 for both the Waikato dairy and Southland sheep and beef systems at CV values between 30% and 40%. For nitrogen on pasture, significant loss in a dairy system occurs at a CV of approximately 40% whereas for a sheep and beef system it is at a CV of 50%, where the financial return from nitrogen application has been calculated at the average gross revenue of the farming system. The conclusion of this study is that the current Spreadmark standards are a satisfactory basis for defining the evenness requirements of fertiliser applications in most circumstances. On the basis of Spreadmark testing to date, more than 50% of the national commercial spreading fleet fails to meet the standard for nitrogenous fertilisers and 40% fails to meet the standard for phosphatic fertilisers.Keywords: aerial spreading, crop response, economic loss, fertiliser, ground spreading, striping, uneven application, uneven spreading, yield loss
