Abstract

Bemisia tabaci is a major pest of soybeans and a vector of plant viruses. This study aimed to evaluate and compare the efficacy of four entomopathogenic fungi for suppressing B. tabaci populations on soybeans. The four treatments were L. lecanii, A. aleyrodis, M. anisopliae, and B. bassiana, a comparison with the insecticide thiamethoxam and a control group without treatment. The four types tested were able to suppress B. tabaci populations by up to 75%, with A. aleyrodis being especially effective. There was no significant difference in efficacy between the four types and the insecticide thiamethoxam. Validating the efficacy of entomopathogenic fungi, there were no significant differences in plant height, dry stover weight, or number of pods between treatments with the insecticide thiamethoxam. However, significant differences occurred in the number of empty pods and seed weight, reducing yield losses by up to 78%. There was a positive correlation between the B. tabaci population and the number of empty pods (r = 0.80), while there was a negative correlation between the B. tabaci population and plant height and soybean yield (r = -0.56 and r = -0.54, respectively).

Abstract

Potatoes (Solanum tuberosum L.) are a strategic horticultural commodity in Indonesia, but their productivity is often hampered by attacks from plant-parasitic nematodes. This study aims to determine the effect of potato varieties on the abundance and structure of plant-parasitic nematode communities in the potato production centre of Solok Regency. Soil samples were collected randomly using the zig-zag method from red and white potato fields at several locations with different elevations. Nematodes were extracted using the Baermann funnel method, followed by population calculation, genus identification, and frequency of occurrence analysis. The results showed that the parasitic nematode community was dominated by the genus Meloidogyne in both varieties, with higher populations and frequency of occurrence in red potato varieties. White potato varieties showed lower total nematode populations with more diverse community structures. These differences indicate the influence of variety on the development of plant parasitic nematode populations. These findings emphasise the importance of variety selection as part of an integrated nematode management strategy in potato cultivation in Solok Regency.

Abstract

Whitefly (Bemisia tabaci) is a major pest on tomato plants. Whiteflies not only attack plants directly but also serve as vectors for viruses that spread diseases such as geminiviruses, causing plants to turn yellow. One alternative for controlling this pest is to use entomopathogenic fungi, such as Beauveria bassiana. This study aimed to isolate a B. bassiana strain that enhances tomato plant resistance to B. tabaci. The experiment was arranged in a Completely Randomized Design (CRD) with six treatments and five replications. The treatments included five isolates of B. bassiana, namely BbWs, TD312, PA221, PD114, and PB21 plus a control. The B. bassiana concentration used was 108 conidia/mL. The fungus was applied by soaking tomato seed lots. Results showed that seed soaking with B. bassiana significantly reduced egg, nymph, and adult populations across all isolates compared to the control. Notably, PA221 and TD312 isolates showed significant nymph suppression. Five weeks after planting, the TD312 isolate resulted in the lowest populations: 20.40 eggs per plant, 7.25 nymphs per plant, and 2.30 adults per plant. Additionally, B. bassiana application affected plant morphology by increasing trichome density; plants treated with TD312 had a trichome density of 616.73 trichomes/cm², higher than the control (295.73 trichomes/cm²). Although statistically comparable to several other isolates on some parameters, TD312 consistently exhibited the lowest pest counts and the highest trichome density, indicating its potential to enhance tomato resistance to B. tabaci by suppressing pest populations and reinforcing trichome density.

Abstract

Background: Spodoptera frugiperda is a pest that causes damage and economic losses to corn plants. One of the biological agents that can be used to control S. frugiperda is the entomopathogenic fungus Metarhizium anisopliae. Objective: This study aimed to determine the most virulent isolate of M. anisopliae against S. frugiperda eggs and to evaluate its effect on larval development. Methods: This study used an experimental method with a Completely Randomized Design (CRD) consisting of 5 treatments and 5 replications. The treatments were (A) M. anisopliae C5IA, (B) M. anisopliae SRJ, (C) M. anisopliae 3B, (D) M. anisopliae Metatek, and (E) control (without fungal treatment). The conidial density used was 10⁸ conidia/ml. The fungus was applied to egg masses of S. frugiperda using a spraying method. The parameters observed were percentage of unhatched eggs, mortality of first instar larvae, percentage of pupae formed, and percentage of adults formed. Data were analyzed using analysis of variance (ANOVA) followed by LSD test at the 5% significance level. Results: All tested isolates of the entomopathogenic fungus M. anisopliae caused egg mortality and affected the life development of S. frugiperda. The percentage of unhatched eggs ranged from 41.92% to 92.00%. The most virulent isolate was M. anisopliae 3B, which was able to control eggs with an unhatched egg percentage of up to 92.00% Conclusions: The isolate M. anisopliae 3B was the most virulent isolate against eggs of S. frugiperda and has potential to be developed as a biological control agent for fall armyworm management.

Abstract

Cabai merah merupakan sumber pendapatan utama bagi petani di daerah Tanah Datar. Masalah utama yang selalu dihadapi oleh petani cabai di daerah ini adalah serangan hama dan penyakit yang dapat menyebabkan kehilangan hasil yang cukup tinggi. Hingga saat ini, pengendalian hama dan penyakit sayuran masih mengandalkan pestisida sintetik yang telah menimbulkan dampak negatif. Untuk itu, perlu dicari alternatif pengendalian yang dapat mengurangi dampak negatif pestisida tersebut, yaitu menggunakan agens hayati seperti cendawan Beauveria bassiana dan Trichoderma sp.Tujuan dari kegiatan pengabdian kepada masyarakat ini adalah untuk memperkenalkan dan memasyarakatkan pengendalian hama dan penyakit menggunakan agens hayati Beauveria bassiana dan Trichoderma sp. Metode kegiatan pengabdian adalah penyuluhan, pelatihan dan praktek lapangan. Minat petani untuk menggunakan agens hayati terutama Beauveria bassiana dan Trichoderma cukup tinggi dan telah memotivasi mereka untuk mengurangi penggunaan pestisida sintetis. Petani juga telah berhasil memperbanyak agens hayati dan membuat kompos limbah pertanian menggunakan Trichoderma.

Abstract

Crocidolomia pavonana is a significant pest on cabbage that reduces the quality and quantity of cabbage. Utilizing microorganisms such as rhizobacteria is an alternative environmentally friendly control that can potentially suppress the development of this pest. The study aimed to obtain rhizobacteria isolates capable of colonizing cabbage tissue and inducing plant resistance to C. pavonana larvae. The research was conducted at the Biological Control Laboratory and Greenhouse, Faculty of Agriculture, Universitas Andalas, Padang. The study used a Completely Randomized Design (CRD) with ten treatments and five replications. The treatment consisted of rhizobacteria isolates, including Bacillus thuringiensis, Bacillus subtilis, Serratia marcescens, Stenotrophomonas maltophilia, as well as a negative control (aquadest sterile) and a positive control (Cypermethrin insecticide). The test was carried out by soaking the seeds in a suspension containing rhizobacteria with a population density of 10⁸ cells/ml. The variables observed were larval mortality, pupa and imago formation percentage, and increased salicylic acid production. The data were analyzed using variance and continued with the LSD further test at the 5% level. The results showed that all rhizobacteria isolates colonized into cabbage plant tissue could kill C. pavonana larvae and inhibit these insects' biological development. B. thuringiensis KJKB7.3 showed better results with the highest mortality value (62.67%). Soaking cabbage seeds with rhizobacteria can increase the content of salicylic acid. Based on this research, the rhizobacteria used in the research have the potential to be developed as biological agents to control C. pavonana.
