Abstract

Citrus is a popular horticultural crop planted in different areas in Indonesia. The needs for fruits increases every year, yet production cannot fulfill market demand. One of the contraints are the red scale pest attacks Aonidiella aurantii (Maskel). The implemeintation of standard operating procedure (SOP) in citrus cultural practices is expected to have effects on the population and intensity of red scale attacks. The research was carried out from January to August 2020 on farmer's orchards located at the center of citrus production in Batu, East Java, Indonesia. This experimental study used the research design theory method. The plots were devided into 2 conditions; first, the plots applied SOP, such as regular pruning, sanitation, and organic fertilizer application. While, the second was the conventional plots representing the common farmer maintenance, farmer of not pruning and cleaning weeds throughout the garden, and using NKP inorganic fertilizer. Every evaluated plot covered 1,500 m2, and 10 plants were systematically sampled from every plot. The parameters included numbers of attacked fruits, the abundance of natural enemies and attack intensity of A. aurantii that were taken from the cardinal directions. The results of the study showed that the implementation of SOP was able to significantly reduce population density and intensity of A. aurantii pest attacks and was able to increase the abundance of natural enemies and the quality of citrus fruit when compared to conventional citrus cultivation methods.
Patogenesitas blastospora dan konidia Lecanicillium lecanii Zare & Gams terhadap Helopeltis bradyi Waterhouse (Hemiptera: Miridae): Pathogenicity of blastospores and conidia of Lecanicillium lecanii Zare & Gams on Helopeltis bradyi Waterhouse (Hemiptera: Miridae) Azhari, Ahmad Alwi; Anwar, Rully; Sartiami, Dewi; Samsudin, Samsudin

Abstract

Helopeltis bradyi, merupakan salah satu hama perkebunan teh yang menyebabkan kerusakan hingga penurunan hasil produksi tanaman. Cendawan Lecanicillium lecanii sebagai musuh alami merupakan pengendalian alternatif yang telah diteliti untuk menekan perkembangan dan populasi H. bradyi. Penelitian bertujuan mengetahui patogenesitas blastospora dan konidia terhadap mortalitas, serta dampaknya terhadap kemampuan makan dan reproduksi H. bradyi. Penelitian menggunakan rancangan acak lengkap dengan sepuluh perlakuan dan lima ulangan, termasuk kontrol positif (insektisida deltametrin), kontrol negatif (akuades), serta konsentrasi blastospora (2,45 × 106 hingga 2,45 × 109 blastospora/ml) dan konidia (2,78 × 106 hingga 2,78 × 109 konidia/ml) L. lecanii. Hasil penelitian menunjukkan bahwa L. lecanii dengan konsentrasi 2,78 × 109 konidia/ml menyebabkan kematian H. bradyi sebesar 86% dan rata-rata 223,89 tusukan pada 7 hari setelah aplikasi. LC50 dan LT50 konidia L. lecanii lebih rendah, yaitu 6,62 × 105 konidia/ml dan 4,44 hari dibandingkan dengan blastospora, yaitu 2,20 × 107 blastospora/ml dan 5,37 hari. Aplikasi L. lecanii dengan konsentrasi 2,45 × 109 blastospora/ml menghasilkan jumlah telur terendah, yaitu 5,40 butir. Blastospora maupun konidia L. lecanii terbukti efektif dalam mengendalikan H. bradyi. Konidia memberikan hasil terbaik dalam mortalitas dan pengurangan aktivitas makan nimfa instar III, sementara blastospora juga efektif meskipun dengan hasil yang sedikit lebih rendah. Hasil penelitian ini menunjukkan L. lecanii dapat menjadi alternatif pengendalian hama yang ramah lingkungan dan berkelanjutan dibandingkan insektisida sintetik.

Abstract

Dengue fever (DF) is a viral disease transmitted by the Aedes aegypti (Linnaeus) mosquito, which has the fastest spreading cases. Drug and vaccines are still unavailable, so the Government is focusing on mosquito control. One method of biological control is to use betta fish (Betta splendens) as predators of Ae. aegypti larvae. Betta fish have various varieties, which may have different abilities in preying on Ae. aegypti larvae. The study aimed to analyze the potential for controlling Ae. aegypti larvae using three varieties of B. splendens fish (multi-colored plakat koi, xanthic morph plakat, and halfmoon varieties) during the day and evening. The test was carried out by inserting 25 Ae. aegypti larvaes into an aquarium containing B. splendens fish. Testing starts at 12.00 and 15.00 WIB and replicated five times. Observations started from the fish started preying on larvae until the fish ate all larvae. The predation ability of each variety of B. splendens fish based on predation time was analyzed using the one-way ANOVA test and the unpaired data t-test. The analysis showed that the multi-colored koi plakat variety preyed Ae. aegypti larvae faster than the xanthic morph plaque variety (P < 0.05) and not significantly different from the halfmoon variety (P > 0.05). There was no difference in the ability of B. splendens fish to prey larvae during the day and evening (P > 0.05). B. splendens fish, the multi-colored koi plaque variety, and the halfmoon variety can be biological predators of Ae. aegypti larvae.

Abstract

The use of bay leaves (Syzygium polyanthum) as an alternative fumigant has the potential to control Araecerus fasciculatus (De Geer (Coleoptera: Antribidae). The objective of this study was to evaluate the bioactivities of bay leaf fumigant tablet (BLFT) with exposure times (24, 48, and 72 h) on adult mortality, oviposition deterrence, inhibition of F1 progeny, and feeding activity of the internal feeder pest, A. fasciculatus. This study was used seven concentration levels of BLFT (i.e., 0, 1.25, 2.5, 3.75, 5, 6.25, and 7.5 ml/l air) replicated four times and arranged in a completely randomized design. The observed variables were adult male and female mortality, number of eggs, F1 progeny, and inhibition of feeding activity. The results showed that bay leaf tablets have very significant potential as a fumigant against A. fasciculatus. Bay leaf tablets fumigant at a concentration of 3.75 ml/l air within 24 hours of application were able 100% inhibit feeding activity, oviposition, F1 progeny, prevent perforation, and weight loss of Katana 1 peanut seeds, and mortality of male and female A. fasciculatus
