Abstract

Identification of fruit flies and the methods of their control are essential to overcome the problem of pests. Using attractants is one of the control methods, which is environmental friendly and leaves no residue on plants. The study aimed to identify the species of fruit flies attacking Siam citrus plants and determine the most effective type of attractants to control their population. Identification was made on the fruit flies captured on attractants, and the study on attractants was conducted using a Randomized Block Design (RBD) consisting of four treatments and five replications. Four treatments (type of attractants) were petrogenol, rongit glue, chery glue, and king super glue. Two species of fruit flies, i.e., Bactrocera dorsalis and B. umbrosa, were found in the citrus plantation in Lambung Bukik Padang. The most effective attractants to control the fruit fly population were rongit glue and super king glue, which trapped the highest number of flies. Rongit glue trapped on the average of 94.2 individuals, and King superglue at 91.0 individuals per week. Rongit glue and super king glue can reduce fruit fly attacks. It is also part of an integrated pest management system to support sustainable agriculture.

Abstract

The gambir plant can serve as a raw material for botanical insecticides. Plant-based insecticides are made in nanoemulsion form to overcome the insecticide particle size problem. This study aims to obtain a gambir waste form that has the potential to be used as a botanical insecticide using nanotechnology. The laboratory experiments include preliminary and follow-up tests. The preliminary test involves testing each extract (liquid, solid, and raw gambir waste) at three concentrations using a completely randomized design with four replications. The follow-up test uses the residue method on leaves to test insecticidal activity. Creating nanoemulsion from gambir waste involves mixing organic and liquid phases through spontaneous emulsification. The insecticidal effectiveness of this nanoemulsion is tested on Croccidolomia pavonana. The results show that solid and liquid gambir waste has the potential to be used as alternative insecticides, which can influence the mortality of C. pavonana with an LC50 concentration of 0.22 (solid waste) and 0. 29 (liquid waste), while LC95 is 2.44 (solid waste) and 2.52 (liquid waste). The research promotes utilizing natural resources and innovative technologies, advancing environmentally conscious pest control methods, and fostering sustainable agricultural systems.

Abstract

Setothosea asigna poses a significant threat to oil palm plantations, necessitating effective control measures. This survey-based research, utilizing Purposive Sampling, identifies parasitoids and evaluates their effectiveness in Dharmasraya oil palm plantations, a crucial palm oil-producing region in Indonesia. The selected criteria encompass plantations aged 6-15 years with a considerable Setothosea asigna infestation, providing a comprehensive overview of the pest's impact. The study establishes five sample points diagonally, each comprising five randomly chosen plants, totaling 25 samples per site, ensuring diverse representation. The predominant larval parasitoids exhibit noteworthy efficacy, primarily from the Hymenoptera order, Braconidae family, Genus Apanteles, and Spinaria. Among the 110 larvae observed, five were parasitized, resulting in the emergence of 65 parasitoids. The parasitization rate varies from 0 - 9.09%, with prominent contributions from Apanteles sp. and Spinaria sp., belonging to the endoparasitoid type. This research significantly contributes to sustainable agriculture practices and the palm oil industry, offering insights into targeted pest control for Setothosea asigna. Despite its focus on Dharmasraya, the study provides a valuable foundation for broader applications and invites further research for generalization.

Abstract

Pests are one of constrains in cassava production. The research was done in cassava plantation in Lima Puluh Kota with the objectives were to determine the species of major pests of cassava and their damages. A survey was conducted in five subdistricts, Akabiluru, Guguak, Harau, Lareh Sago Halaban and Situjuah Limo Nagari. Twenty sampled plants were taken in 400 m2 plot laying in the middle of 0,5 hectar cassava plantation, 4-5 months. Four species of pests were found to attack cassava plants in Lima Puluh i.e: Paracoccus marginatus, Pseudococcus jackbeardsleyi, and Ferrisia virgata, whitefly, Aleurodicus dispersus. The three mealybugs caused percentage of plant attacked 85.5 %, percentage of leaf plant attacked 8.61 %, pest population 52.29 individual per plant with damage intensity was high. Whitefly caused percentage of plant attacked 12%, percentage of leaf plants attacked 0.77%, pest population 1.51 individual per plant.

Abstract

Spodoptera exigua is the primary pest attacking shallot plants from the vegetative to the generative phase. Yield loss caused by S. exigua attack can reach 57%. Rhizobacteria have been known to be used as biocontrol agents for controlling insect pests. The research objectives were to determine and compare the effectiveness of Yuyaos and BPTPH rhizobacteria formula (Bacillus sp.) in suppressing the attack of S. exigua on shallot-growing areas. The study used a completely randomized design (CRD) of 3 treatments and five replications. The treatment consisted of shallot seedlings treated with two types of rhizobacteria (Yuyaos and BPTPH) and water (without rhizobacteria) as control before planting. Beneficial effects of the rhizobacteria on shallot plants were observed in the following variables, including the development of the S. exigua population, damage level of S. exigua, and shallot growth. The results showed that introducing Yuyaos rhizobacteria (RZ2.1AG1, Bacillus thuringiensis), which originated from the rhizosphere of the chili plant, was the best way to protect shallot plants from S.exigua. Effectively reduced the population of S.exigua (78.90%), leaf damage (62.12%), and damage intensity (38.88%). On the other hand, Yuyaos was also influential in increasing tuber growth (11.11%), plant height (43.29%), number of leaves (58.33%), and number of tillers (22.22%).

Abstract

Wereng perut putih (Stenocranus pacificus Kirkaldy) merupakan salah satu hama yang menyerang tanaman jagung di Kabupaten Padang Pariaman. Penelitian ini bertujuan untuk mengetahui kepadatan populasi dan gejala serangan wereng perut putih pada tanaman jagung yang ditanam secara monokultur di kabupaten Padang Pariaman. Penelitian ini dilaksanakan pada lahan pertanaman jagung milik petani di nagari Pakandangan dan nagari Gadur, Kecamatan Enam Lingkung, dan nagari Campago, kecamatan V Koto Kampung Dalam, Kabupaten Padang Pariaman, Provinsi Sumatera Barat. Penelitian ini dilaksanakan pada bulan Februari – Mei 2025. Metode yang digunakan dalam penelitian ini adalah metode survei, dengan pemilihan lahan sampel ditetapkan dengan kriteria luas area minimal 1 Ha. Pada setiap lahan ditentukan sebanyak 5 petak sampel yang ditentukan secara diagonal, yaitu 1 petak terletak di perpotongan garis diagonal dan 4 petak lainnya terletak pada garis diagonal dengan jarak 5 m dari sudut petakan. Setiap petak sampel berukuran 1 x 1m. Masing-masing petak sampel terdiri dari 12 tanaman jagung, sehingga jumlah sampel tanaman jagung yang diamati secara keseluruhan sebanyak 60 tanaman. Data diolah dengan excel. Hasil penelitian menunjukkan bahwa kepadatan populasi dan serangan S. pacificus pada tanaman jagung di Kabupaten Padang Pariaman sangat dipengaruhi oleh jenis varietas tanaman jagung. Selain itu, kepadatan populasi S. pacificus cenderung lebih tinggi pada fase vegetatif dibandingkan fase generatif
