Abstract

Plant diseases and pests are important factors determining plant yield production, including mango. Mango fruit rot caused by insects and microbes has become a significant threat to mango production in Southeast Asia and worldwide. Insect plant pathogens affect crop yields' profitability, quality, and quantity. Some infections could occur before harvest and remain dormant until the favourable condition is achieved, and the disease will break out after harvest, reducing mango production. They act as a threat to the crops through various mechanisms of pathogenesis that compromise the immune system of the plants, such as developing any ways to attack the plants, seeking entry via open pores or exposed surface or wound, and sourcing nutrients forcefully for their growth and development. Depending on the environmental factors, the insect contracts the host through primary or secondary infection. This paper summarizes mango fruit rot disease caused by insects groups such as fruit borers (Autocharis albizonalis and Citripestis eutraphera), fruit flies (Bactrocera dorsalis), and mango seed weevils (Sternochetus mangiferae). This review will provide information about fruit rot diseases on mangoes caused by insects, the mechanism of infection, the interaction between insect damage and fungal infections, effective control methods, and related integrated pest management approaches.

Abstract

Field experiments were conducted at El-Mattana Agricultural Research Station, Luxor Governorate, during two successive wheat growing seasons (2017/18 and 2018/19). This was to study the seasonal abundance of Rhopalosiphum padi (Hemiptera: Aphididae) on wheat plants (Giza 171 cultivar). We also investigated the effects of climate and plant phenology on the R. padi population density. Results indicated that R. padi infested wheat plants from December 17, 2017, until April 8, 2018, within the first growing season (2017/18), and from Jan. 27th, 2019, up to April 13th, 2019, within the second growing season (2018/19). The cumulative counts of R. padi in growing season one was 9486.17, and in growing season two, 3444.00 individuals. The mean population of R. padi per 10 tillers over the whole first season was 80.12 ± 7.90, and for the second season, 42.36 ± 2.96. The first season, December, January, and February, had the most favorable climate for R. padi population growth (measured during weekly inspections). In contrast, February and March were more favorable in the second season. R. padi was not detected on the wheat during the wheat maturation period within both growing seasons. The combined effects of climate and plant phenology strongly correlate with R. padi population density, with explained variance (EV) of 93.86% in the first season and 99.11% in the second season. Daily mean maximum temperature was the most influential variable explaining changes in total R. padi population, with EV 28.37%in the first season and 28.62% in the second season. The data provided here can assist in the design of Integrated Pest Management (IPM) programs for aphid control on wheat plants.

Abstract

West Sumatra Province is one of the cocoa production centers in Indonesia. Cocoa farmers in the Lima Puluh Kota District in West Sumatera Province had successfully developed a superior clone of cocoa plants resulting from participatory selection, which was later coded BL-50. The main pests that attack cocoa plants are the urgent problem in cocoa cultivation, resulting in decreased productivity. This study aims to determine the level of significant pest attacks on cocoa varieties BL-50 in Tanah Datar Regency. This research is in the form of a survey with a purposive sampling method. Sampling is carried out systematically diagonally in the field. The highest attack rate of Cocoa Fruit Borer in Tanah Datar Regency is in Rambatan District, with the percentage of affected plants, the percentage of infested fruits, and the highest attack intensity, respectively 51,.25%; 31.58% and 21.10%, the lowest were in Lintau Buo Utara District with 30.93%; 20.70% and 13.96%. The highest attack rate of cocoa fruit-sucking ladybugs in the BL-50 variety is in Rambatan District, 66.09%, 45.07%, and 30.45%. At the same time, the lowest is in the Lintau Buo Utara District, with a percentage value of 41.56%, 27.66%, and 18.30%. Excellent and regular land sanitation activities have played a role in minimizing the level of pest attacks in Lintau Buo Utara.

Abstract

Plant diseases and pests are important factors determining plant yield production, including mango. Mango is an economically important fruit crop in tropical and subtropical areas. Mango fruit rot caused by insects and microbes has become a significant threat to mango production in Southeast Asia and worldwide.

Abstract

With the rising demand for sustainable protein sources and effective waste management solutions, Black Soldier Fly (BSF) larvae (Hermetia illucens) have gained attention for their ability to convert organic waste into high-protein biomass. This study investigates the effects of different organic substrates on the growth and nutritional quality of BSF larvae, aiming to identify optimal substrate types for enhancing protein production and supporting sustainable waste management. Conducted in Tomay, La Trinidad, Benguet from January to March 2022, the experiment compared the larval development duration, crude protein content, and associated rearing costs of BSF larvae fed with cabbage trimmings (control), banana peelings, and retrograded rice. The larvae’s development period, from first to sixth instar, ranged from 15 to 17 days under room temperature conditions of 24°C to 30°C and relative humidity levels between 52% and 99%. Results showed that larvae fed on banana peelings achieved the highest crude protein content at 17.81% with a moisture content of 61.11%, followed closely by cabbage trimmings with 17.34% protein and 64.22% moisture, and retrograded rice with 16.82% protein and 63.96% moisture. These differences in protein and moisture content suggest that substrate type significantly influences the nutritional quality of BSF larvae, with implications for their use as a sustainable protein source. In terms of cost, rearing BSF larvae on banana peelings resulted in the highest expenses (PhP3,343.00), followed by cabbage trimmings (PhP3,104.00) and retrograded rice (PhP2,970.00), with total experimental costs amounting to PhP9,509.50. This study highlights that substrate choice affects not only the growth rate and nutrient content of BSF larvae but also the economic feasibility of BSF rearing.

Abstract

The fall armyworm (Spodoptera frugiperda) is a serious crop pest that destroys maize plants in Egypt and the world, leading to reduced quality and quantity of the maize crop. We conducted this study to monitor and determine the damage status and infestation frequency of S. frugiperda on maize plants in Luxor Governorate, southern Egypt. The sampling date was set with the first observable occurrence of fall armyworm at the study site. Forty randomly selected corn plants (ten plants from each replicate) were evaluated and estimated weekly until harvest. The total number of plants used for sampling was 960 plants during the two seasons. The invasion and damage of maize plants by S. frugiperda started at the age of 16 days after sowing until the time of harvest, i.e. S. frugiperda larvae were detected on maize plants during the period from the third week of June until the maize harvest. In terms of number of larvae, number of plants infested with larvae, percentage of infestation, and percentage of damage intensity, three peaks were recorded in each season, occurring at 30, 58 and 86 days after sowing in 2021 and 2022, respectively. Our study shows that the number of damaged plants was higher than the number of infected plants throughout the season. Thus, the percentage of plants damaged by S. frugiperda increased as the timing of corn plant inspections increased during the two seasons. The results indicate that monitoring plant inspections at key times during the growing season can provide crucial data to help farmers implement timely control measures.

Abstract

Culex mosquito is able to act as transmission vector of filariasis and Japanese encephalitis. Both diseases occur in Indonesia and filariasis exists in Banyuwangi district. The Voltage-Gated Sodium Channel (VGSC) gene mutations are related to pyrethroid insecticide resistance, especially L1014F/S mutations have not yet been fully studied in Indonesia. This study aimed to investigate the polymorphism of VGSC gene mutation in Culex mosquitoes in Banyuwangi District of East Java Province, Indonesia. Culex mosquitoes were collected using mosquito trap in a two-day collection from Banyuwangi Sub-district and two sub-villages in Cluring Sub-district of Banyuwangi District in August 2023. Culex mosquitoes were identified by morphological examination and Culex DNA was extracted by Chelex100 from each Culex mosquito. The polymorphism of VGSC gene mutations of L1014F/S were determined by Allele Specific-Polymerase Chain Reaction (AS-PCR). A total of 62 Culex mosquitoes were analyzed. The wild type Culex mosquitoes were found predominant (77%, 48/62). Two types of homozygous mutations were identified as 1014F and 1014 S (16%, 10/62 and 2%, 1/62, respectively). The heterozygous mutation was only 1014F/S type with frequency of 5% (3/62). The predominance of wild type Culex mosquitoes indicated that Culex population in the study areas is still susceptible to pyrethroid insecticide. However, the mutant types of Culex are already occurred, so insecticide resistance among Culex mosquitoes is required to be regular monitoring.

Abstract

Cashew is a significant export crop in Burkina Faso but suffers substantial damage from the cashew wood borer Apate terebrans Pallas. Despite its economic importance, the population dynamics of this beetle have not previously been studied in Burkina Faso, limiting the development of effective control strategies. This study monitored infestation patterns on 960 cashew trees randomly selected from 8 localities in 4 regions across two agro-ecological zones. The trees were inspected monthly over two consecutive years according to typical producer management practices. As A. terebrans bores inside branches and trunks, direct observation of adults was unfeasible. Therefore, infestation rates were estimated by counting fresh entry holes monthly. Over the study period, infestations began in July, peaked in November–December, and declined to zero by May–June. Infestation rates differed significantly between years (p < 0.001), among regions (p < 0.001) and localities (p < 0.02), and were influenced by cashew tree phenology (p < 0.01), suggesting that A. terebrans preferentially infests uncleaned orchards and trees at more vulnerable phenological stages. These findings underscore the need for targeted orchard sanitation practices to reduce infestations, as well as the importance of sampling plans and population monitoring to support higher cashew yields and economic returns.

Abstract

The nettle caterpillar, Darna diducta, is a significant pest in oil palm plantations, causing damage to palm fronds that impacts overall plant health and yield. Traditionally, synthetic insecticides are used to manage this pest; however, such intensive chemical use has led to adverse effects, including pest resistance, resurgence, and environmental degradation. Entomopathogenic fungi like Metarhizium rileyi (formerly Nomuraea) represent a promising, environmentally friendly alternative for pest control. This study focused on the natural occurrence of M. rileyi infections in D. diducta larvae within oil palm plantations in East Pamona, Poso Regency, Central Sulawesi, observed in August 2015. Surveys conducted across several villages found a remarkable 100% infection rate of D. diducta larvae by M. rileyi, with each infected larva exhibiting extensive fungal growth, characterized by white mycelium covering the entire body. The resulting impact on palm frond damage was minimal, with the percentage of plant damage due to D. diducta categorized as mild, ranging from only 0.24% to 0.34%. These findings indicate that M. rileyi effectively suppresses D. diducta populations, reducing pest severity and frond damage. The high infection rate and its impact on pest control underscore M. rileyi’s potential as a natural biocontrol agent, offering a sustainable approach to managing D. diducta infestations. Thus, integrating M. rileyi as a biological control method could significantly benefit oil palm cultivation by minimizing chemical use, promoting ecological balance, and supporting long-term pest management strategies.

Abstract

Hymenoptera are vital for maintaining ecological balance in rice agroecosystems. These insects provide essential ecosystem services, particularly in biological pest control, reducing the reliance on chemical pesticides. Despite their importance, the impact of different agricultural practices on Hymenoptera diversity and their ecological roles in Indonesian rice fields remains underexplored. This systematic review aims to assess the diversity and ecological functions of Hymenoptera in Indonesian rice agroecosystems, evaluate their contributions to natural pest suppression, and examine how various management practices, including organic farming and Integrated Pest Management (IPM), affect Hymenoptera populations. A comprehensive search of peer-reviewed studies from Scopus, Web of Science, and Google Scholar was conducted. Inclusion criteria focused on studies reporting Hymenoptera species diversity, ecological roles, and the effects of different rice farming practices. Data on species composition, pest suppression rates, and management practices were synthesized and analyzed using statistical methods, including regression and ANOVA.The findings reveal significant variation in Hymenoptera diversity across regions, with organic and IPM practices supporting higher species richness than conventional methods. A strong positive correlation was found between Hymenoptera diversity and pest suppression rates, particularly during the reproductive stage of rice growth. Parasitoids and predators played dominant roles in controlling key rice pests.Conserving Hymenoptera diversity through sustainable farming practices is crucial for reducing chemical inputs, improving pest control, and enhancing the resilience of rice agroecosystems. Future agricultural strategies should integrate biodiversity-friendly practices to ensure long-term sustainability in rice production.
