Entomopathogenic fungi from the lowland soil of South Sumatera and their potential as biocontrol agents of Stink Bug (Leptocorisa oratorius (F.)). The purpose of this research was to explore and examine the potential of soil borne entomopathogenic fungi from South Sumatera as biological agents of Leptocorisa oratorius (F).  Soil used for trapping entomopatogenic fungi, was taken from five locations  in South Sumatera.  Percentage of nymph mortality was analyzed by using analysis of variance and arranged in Completely Randomized Design.  LT50­ of nymph mortality was determined with Probit Analysis.  Entomopathogenic fungi found in this research were Beauveria bassiana and Metarhizium sp.  Stink bug mortality due to B. bassiana isolates reached 40-73.3% and Metarhizium sp. reached 56.7-70%. The results showed that Metarhizium isolates were more virulent than B. bassiana isolates.  The viability of B. bassiana conidia did not decrease during sub-culturing.  Sub-culturing did not influence the mortality of stink bug nymph but it prolonged the LT50­  of the stink bug.

This study aimed to evaluate the oviposition preference of the Neotropical brown stink bug, Euschistus heros (F.) on artificial substrates of different colors (felt woven). For this, ten pairs of stink bugs were transferred into plastic pots. Each pot contained seven felts of 6x20 cm (100% polyester-atoxic) of different colors (white, black, blue, green, red, yellow and brown). The pots were evaluated daily for three weeks (21 days) being counted the number of eggs, clutches and eggs per clutch for each color of felt. The choice test was set in a completely randomized design. Data obtained was submitted to the analysis of variance and means were compared by Scott-Knott test at 5% probability. During the evaluation were produced 7074 eggs distributed in 977 clutches, accounting a mean of 7.06±0.67 eggs per clutch. Results indicated that females laid a significantly greater number of eggs (2380 and 1686) and a greater number of clutches (319 and 233) on the yellow and white felts, respectively, than on the remaining substrates. The substrates in color red, black and brown were the least preferred, and the colors blue and green were intermediate when compared with others. Therefore, the substrates colored yellow and white are suggested to be used in rearing E. heros in the laboratory.

Aedes aegypti is a major vector of dengue, a deadly disease causing deaths of millions of people in developing countries, both in urban and rural populations. Aedes aegypti control with chemical insecticide is widely used, and affects on a widespread insecticide resistance. Mosquito biological control was needed to replace the use of chemical insecticide. This study aimed to evaluate larvicidal effect of mixture of Beauveria bassiana crude metabolite and chitinase enzyme against Aedes aegypti larvae. An experimental study using completely Randomized Design was conducted in March-April 2016 at Banjarnegara Research and Development Unit for Zoonosis Control. Biolarvacide formula was made of mixture with 2 : 1 ratio between Beauveria bassiana crude metabolite and chitinase isolated from chitinolytic bacteria, which was propagated by the Agency’s Bacteriology Laboratory. In experimental method, 120 Aedes aegyptilarvae (3rd instar) were exposed with four concentrations of biolarvacide formula (4%, 8%, 16%, and 32%) in 3 replicates. Results showed that exposure of biolarvacide formula caused the third instar larval mortality which started on the first day of exposure. Probit analysis showed LC50 value was obtained at concentration of 53.2 ppm. This shows that larvacide formula of Beauveria bassiana and chitinase enzyme compounds are effective to be used as larvacides against Aedes aegypti larvae.

ABSTRACT: The use of plant species for the phytoremediation of soils contaminated with herbicides is an alternative that has been emphasized to minimize the effects of the persistence of agrochemicals in the environment. The objective of this study was to evaluate the tolerance potential of winter species in soils contaminated with sulfentrazone and fomesafen. The experiment was in a completely randomized design with four replications. Doses of fomesafen (0.0, 0.125, 0.250, and 0.5 kg ha-1) and sulfentrazone (0.0, 0.3, 0.6 and 1.2 kg ha-1) were applied during the pre-emergence of phytoremediate species (black oat, vetch, birdsfood trefoil, radish and lupin). Forty five days after the emergence of the species, the phytotoxicity (%), leaf area (cm2), stalk and/or stem diameter (mm), height (cm) and dry matter (g) variables of the plants were evaluated. Data were submitted to analysis of variance by F test; when significant, linear or non linear regressions were applied to evaluate the effect of herbicide doses on the studied species. Birdsfood trefoil was the less tolerant species to fomesafen and sulfentrazone. Black oat was less affected by the application of fomesafen doses, but it was highly susceptible to sulfentrazone. Radish presented tolerance only up to the fomesafen dose of 0.25 kg ha-1; as for sulfentrazone, the species showed tolerance. The most tolerant species to fomesafen and sulfentrazone, regardless of the dose, was the lupine, which is a possible alternative for the phytoremediation of soils contaminated with these herbicides.

Depuration is an effort to reduce/eliminate contamination including microplastics, which one is using a water circulation system. This study aims to determine the effective depuration time to reduce the microplastic content in Asaphis detlorata This study used a quantitative approach with experimental research design with a completely randomized design. There are 450 shells used as an experimental animal where is the treatment consisted of four depuration times, namely 1;2;3; and 4 days with 3 repetitions of each treatment, while the control shells were without depuration. Analysis of variance (ANOVA) was used to see the effect of depuration treatment on the microplastic content. If the effect of the treatment was significantly different, then the post hoc test was continued to determine the differences between treatments. The results showed that Asaphis detlorata obtained from the mouth of the Lakatong river estuary were contaminated with microplastics ranging from 0.6 to 8.1 MPs/shellfish and an average of 3.96 MPs/shellfish. Depuration time significantly affected the microplastic content in shellfish depuration effectiveness. There is a tendency that the longer depuration time is decreased microplastic content in shellfish. The effective depuration time to reduce the microplastic content in Asaphis detlorata was 3 and 4 days. Further research is needed for a more effective depuration for cleaning microplastics in shellfish.

Red spinach (Amaranthus gangeticus) is one of the most popular vegetables because of its high nutritional value and easy cultivation. Efforts to increase the production of red spinach are to fertilize to meet the needs of both macro and micronutrients. This study aimed to determine the effect of ZA fertilizer dose on the growth and yield of red spinach. The environmental design used was a non-factorial, completely randomized design with four replications. The factors tested were the dose of ZA fertilizer which consisted of 6 levels, namely: without ZA fertilizer (D0); 0.4 gr/polybag (D1); 0.8 gr/polybag (D2); 1.2 gr/polybag (D3); 1.6 gr/polybag (D4); 2 gr/polybag (D5). The data obtained were analyzed using analysis of variance, and if the results were significantly different, the BNT test was continued at a 5% level. The growth and yield of red spinach showed significant differences due to the ZA fertilizer dose treatment. The ZA fertilizer dose treatment of 1.2 g/polybag (D3) resulted in the highest plant height, the number of leaves, and leaf area of red spinach at 14, 21, and 28 days after planting. The ZA fertilizer dose treatment of 1.2 g/polybag (D3) resulted in the highest wet and dry weight plants of 49.15 and 4.38 grams, respectively. The ZA 1.2 gr/polybag dose is the ideal dose to increase the productivity of red spinach.Bayam merah (Amaranthus gangeticus) termasuk sayuran penting yang disukai masyarakat karena bernilai gizi tinggi dan mudah pembudidayaannya.

One of the entomopatogenous fungus types commonly observed and showed potency as myco-insectiside is Beauveria bassiana(Bals.) Vuill.In order to support effectiveness and patogenous activity of B. bassiana, it is necessary to add a carrying agent that protects its spores from ultra violet ray. This study aims to investigate the effect of storage temperature on viability of B. Bassianaspores on the carrier material. The observation was carried out in the Laboratory of Plant Diseases, Indonesian Coffee and Cocoa Research Institute. The research was arranged in completely randomized design by three factors. The first factor was carrier (C), that consists of C1 = rice flour, C2 = maize flour and C3 = tapioca flour. The second factor was dosage (D), that consists of D1 = 1 g B. bassiana+ 1 g carrier; D2 = 1 g B. bassiana+ 5 g carrier and D3 = 1 g B. bassiana+ 10 g carrier. The third factor was temperature of the storage (T),that consists of T1 = 5oC; T2 = 23oC and T3 = 29oC. Viability of B. Bassiana spores was examined by observing development of 100 blastopores randomly and determined under light microscope with 400 times magnification. Observation was conducted in two replicates after the spores of B. bassiana were kept in the storage for 2, 4, 8 and 16 weeks. The result showed that by adding 1 g tapioca flour and temperature of storage of 5oC was potentiall in keeping viability of B. bassianaspores at least for 2 months. It was due to that tapioca flour gave better effect than rice and maize flours in keeping the storage and appropriate low temperature. Viability of B. bassianaspores decreased with increasing carrier dosage, temperature and duration of the storage. Whereas, storage at 5oC was found to be a better condition in keeping viability of dry pure B. bassianaspores longer than conditions of 23o and 29oC. Key word:Beauveria bassiana, temperature, viability,carrier.

EFFECT OF REPLACEMENT OF CORN WITH SORGUM Cv. KAWALI IN PELLET RANSUM ON LOCAL RABBIT PERFORM. The purpose of this study was to determine the effect of substitution corn with sorghum in rabbit rations on feed consumption, body weight gain, and ration conversion. The duration of the study was 28 days using 20 local rabbits. The statistical design used in this study was a completely randomized design, with 4 (four) treatment rations and 5 (five) replications. The four experimental rations, namely R0: 45% corn + 0% sorghum, R1: 30% corn + 15% sorghum, R2 15% corn + 30% sorghum, R3 0% corn + 45% sorghum. Variables were measured, viz: feed consumption, body weight gain and ration conversion. The results showed that the average of feed consumption, body weight gain, and feed conversion, were: 28.27–30.59 g /head /day, 15.76–21.55 g / head /day, and 1.42-1.80 g /head /day, respectively. Based on the analysis of variance, the treatments ration had no significant effect (P> 0.05) on consumption, but had a very significant effect (P <0.01) on body weight gain and feed conversion. The LSD test showed that all treatment rations using sorghum (R1, R2, and R3) gave results of body weight gain which were very significantly different (P <0.01) and higher than R0. Whereas, on ration conversion, treatments R1, R2, and R3 give very different results (P <0.01) lower than R0. It is concluded that the substitution of corn with sorghum at the level of 45% in the ration gives the highest results for body weight gain and conversion of rations for rabbits. Keywords: corn, sorghum, ration, performance, local rabbit
