Abstract

Hama pascapanen merupakan salah satu penyebab utama yang dapat menyebabkan susut bobot dan kualitas pada komoditas pangan dalam simpanan. Sebagian besar petani yang menyimpan gabah dan beras dalam waktu yang lama masih belum memperhatikan dengan serius mengenai ancaman serangan hama pascapanen, padahal infestasi hama pascapanen dapat menimbulkan kerugian baik secara langsung maupun tidak langsung. Oleh karena itu, kegiatan pengabdian masyarakat ini bertujuan untuk melakukan pengenalan hama pascapanen pada bahan pangan dalam simpanan, khususnya gabah dan beras kepada petani. Kegiatan ini dilakukan pada bulan Mei sampai dengan Agustus 2024 di Desa Pendem, Kecamatan Junrejo, Kota Batu. Kegiatan ini terdiri dari tiga tahapan, meliputi survei lokasi dan pengambilan sampel, identifikasi hama pascapanen, dan pengenalan hama pascapanen yang diperoleh dari gudang milik kelompok tani. Kegiatan survei yang dilakukan pada beberapa gudang milik kelompok tani menunjukkan adanya infestasi hama pascapanen pada dua gudang gabah dan beras. Spesies serangga hama pascapanen yang ditemukan meliputi enam spesies serangga. Pelaksanaan kegiatan pengenalan hama pascapanen diikuti oleh 50 peserta dan seluruh peserta menunjukkan tingkat partisipasi dan antusiasme yang tinggi. Kegiatan pengabdian masyarakat ini diharapkan dapat meningkatkan pengetahuan dan kepedulian petani tentang pentingnya hama pascapanen. Selain itu, petani juga mampu mengembangkan teknik penyimpanan yang mempertimbangkan aspek pencegahan infestasi hama pascapanen.

Abstract

The almond moth Cadra cautella (Walker) is a notable stored product pest which can cause detrimental loss on stored cocoa. Cocoa can be stored in bean and powder forms. The information about survival and development of C. cautella on stored cocoa is limited. This research aimed to determine the effect of cocoa powder and cocoa bean in the storage against the survival and development of C. cautella. This research was conducted in Plant Pests Laboratory, Department of Plant Pests and Diseases, Faculty of Agriculture, Universitas Brawijaya. This research consisted of two treatments namely cocoa bean and cocoa powder with no choice method and repeated six times. The observed variables were number of larvae, pupae, male and female almond moth of F1 progeny, and developmental time of this insect. The t-test analysis was applied to determine the treatment effect. Results showed that the number of larvae, pupae, adult males and females of F1 progeny cultured on cocoa powder were significantly higher than on cocoa bean. The total developmental time and life cycle of almond moth were shorter on cocoa powder than on cocoa bean. Therefore, to store cocoa in powder form is riskier to the almond moth infestation rather than in bean form. Hence, it is suggested to take more concern on the cocoa powder storage better in order to minimize the almond moth infestation.

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

Abstract

Tribolium confusum Jacquelin du Val (Coleoptera: Tenebrionidae) is a major stored product pest that can damage flour in storage. The infestation of T. confusum causes contamination of stored grain, such as flour. Research about the population growth of T. confusum in various commercial and non-commercial flours is still limited. This study aims to determine the population growth of T. confusum in various commercial and non-commercial flours. The study was conducted using the no-choice test method (NCTM). This study used a treatment jar containing 30 g of diet and infested 15 pairs of T. confusum adults for 7 days. Data obtained from this research were analyzed using analysis of variance (ANOVA) and further analyzed using the Duncan Multiple Range Test (DMRT) at a 5% significance level. The results showed that the number of larvae, pupae, and F1 progeny of T. confusum was higher in non-commercial red rice flour (80, 50 individuals; 59, 50 individuals; 57, 50 individuals) compared to other types of flour. The chemical characteristics of diets that can affect the population growth of T. confusum include fat, ash, carbohydrate, and phenol content. In conclusion, understanding the chemical characteristics of flour is crucial for developing a strategy to control T. confusum.

Abstract

The coffee bean weevil, Araecerus fasciculatus (DeGeer) (Coleoptera: Anthribidae), is a significant polyphagous stored product pest known to cause severe damage, including perforation and hollowing, in stored maize. This study aimed to determine the adult presence and oviposition preference of A. fasciculatus across twelve commercial maize varieties, and to analyze the correlation between preference and specific grain characteristics. The free choice test method (FCTM) was employed using preference cages with 12 or 6 chambers. In each test, 30 g of maize were infested with 60 pairs of 7- to 14-day-old A. fasciculatus adults for seven days. Adult presence (total and by sex) was recorded daily, and the number of eggs laid was counted microscopically at the end of the infestation period. The composition of maize varieties significantly affected adult presence and oviposition. Results consistently showed that the Pertiwi 3 variety was the most highly preferred for both adult presence (21.86 individuals in the 12-variety test) and oviposition (22.75 eggs in the 12-variety test). This high preference was supported by the Perkasa variety (e.g., 13.54 adults), which was also consistently preferred across the different test compositions. Further analysis using the generalized linear model (GLM) indicated that the preference is driven by grain quality: adult presence showed a positive correlation with moisture content, while oviposition exhibited a negative correlation with phenol content. These findings suggest that the Pertiwi 3 variety, likely due to its favorable physical attributes and low levels of chemical defense, is the most susceptible to A. fasciculatus infestation.

Abstract

Rhyzopertha dominica is a polyphagous stored pest to many grains including rice. R. dominica can easily spread from one place to another to infest stored products. The aim of this research was to know the influence of three grains types with different weight to R. dominica growth, development, net reproduction rate and gross reproduction rate on red, black and white rice. The research was conducted in Pest Laboratory, Department of Plant Pests and Diseases, Faculty of Agriculture, University of Brawijaya Malang. The research result showed that there was an interaction among three grains types with different weight to the number of R. dominica larval, pupal, and newly adult emerged, while the number of eggs, weight of newly adult emerged, the reduction percentage of grain and phase of the egg, larval, pupal and the life cycle period of R. dominica were affected by different grains types factor. The R0value showed that on the next generation, number of female was increase 1.25 times from the previous generation on white rice, while on red and black rice the population was increase up to 2.63 and 2.49 times from the previous generation.Keywords: Growth and Development, Reproduction Rate, Rice, Rhyzopertha dominica.
