Abstract

Golden snail is one of the important pests that attack paddy crops. The structure of golden snail is divided into 3 based on the size of the shell diameter, namely juveniles (0.5-1 cm), preadults (1-2.5 cm), and adults (2.5-4 cm). The paddy cultivation system can affect the golden snail population. The purpose of this study was to determine the density, distribution and population structure of the golden snail (Pomacea canaliculata L.) with case studies in Cicalengka (conventional field) and Ciparay (organic field), District of Bandung, from October 2020-January 2021. This research used survey method with sampling technique in purposive sampling.  At each location divided into 5 fields with sized 10x5 m which were divided into 7 quadrant plots. Sampling was carried out at the age of paddy crops 14,21,28, and 35 days after planting. The observerd parameters were density, distribution pattern using the Index of Morisita (Id) and population structure of P. canaliculata. The results showed that the density of P. canaliculata in organic field was higher than in conventional field. The average population structure of pre-adult golden snails in organic and conventional rice fields was significantly different at 14-35 days after planting (DAP) and adult golden snails at 14, 28, and 35 DAP. Distribution pattern of P. canaliculata in organic and conventional were grouped.

Abstract

Crocidolomia pavonana is an important pest that attacks the Brassicaceae. Neem cake is waste from neem seed pressing that can be used as a botanicals insecticide to control insect pests. The effect of the initial temperature of extraction can have an impact on the toxicity of the extract. The aim of this study was to determine the best initial temperature for the extraction of neem cake on mortality, larval development time, feed consumption, larval weight and survival of larvae into pupae and adult. The experimental method used in this research was Randomized Completely Design (RCD) with 4 treatments and 4 replication, i.e. control, extraction of neem cake at initial temperature of 30°C, initial temperature 50°C, and initial temperature 70°C which allows two concentrations of 1% and 3%. The results of the research with the best toxicity were shown in the initial extraction temperature of 50°C at concentrations of  1% and 3% with the mortality reaching 82.5% and 90%. The initial temperature extraction of 50°C also showed lengthened of the larval development time, decreased feeding activity, larval weight and survival of larvae to develop into pupae and imago.

Abstract

Anthracnose caused by Colletotrichum sp. is a major disease on  avocado fruit. An alternative to control this post harvest disease is by using biocontrol agents, such as yeasts. The research was objected to test the abilities of three yeast isolates i.e. Aureobasidium pullulans Dmg 11 DEP, Rhodotorulla minuta Dmg 16 BE and Candida tropicalis Lm 13 BE, to inhibit the in vitro growth of Colletotrichum sp. The experiment was arranged in the completely randomized design consisting of five treatments that were repeated four times each. The treatments were dual culture and double dish system of the culture of Colletotrichum sp. vs the yeast isolates as follow A. pullulans Dmg 11 DEP, R. minuta Dmg 16 BE, C. tropicalis Lm 13 BE, fungicide mancozeb, and a control. The results showed that the three yeast isolates were able to inhibit the colony growth of Colletotrichum sp. by 19,9% – 56,10%  on the dual culture and 15,56% – 26,08% on the double dish system. The yeasts caused abnormal growth of the Colletotrichum sp. hyphae, such as swollen, curly, rolled, and lysis. A. pullulans Dmg 11 DEP caused the highest inhibition, with the category of strong antifungal activity on dual culture, and moderate on double dish system.  It was concluded that the three yeast isolates have the ability to inhibit the in vitro growth of Colletotrichum sp. the caused of  anthracnose on avocado fruit.

Abstract

Anthracnose disease caused by Colletotrichum gloeosporioides considered a major disease on papaya fruit. One way to control plant diseases is to use antagonistic fungi as biocontrol agents. Several antagonistic fungi can be found in plant tissues (endophytic fungi). This study aims to get endophytic fungi from papaya fruit antagonistic to the fungus C. gloeosporioides. The research used a Completely Randomized Design (CRD) consisting of four treatments and five replications on in-vitro and in-vivo tests. The results showed that three isolates of endophytic fungi found from papaya fruit were Fusarium sp., Aureobasidium sp., and Acremonium sp., which had an inhibition of 63.5%, 67.86%, and 7.52%, respectively. Fusarium sp. and Aureobasidium sp. are potentially considered antagonist fungi in controlling the fungus C. gloeosporioides in in-vitro testing based on the inhibition results were more than 60%. Aureobasidium sp. is considered potential antagonist fungi according to the colonization or growth of C. gloeosporioides mycelium inhibition that emerges on papaya up to 97%.
