Abstract

Armyworms are very common and can attack all types of plants. Attacking ornamental plants such as flowers is no exception. This study aimed to determine the types of fall armyworms that attacked lilies in a Bogor, West Java house. It turned out to be an obvious symptom of the attack, the leaves became bald, attacked from the leaves to the base of the stem, and the dirt and the previous attack became wet. Armyworm larvae are dark grey, with eye-catching yellow stripes in the late larval stage. The larvae and adults were identified as a group of armyworms of Spodoptera picta (Lepidoptera: Noctuidae). They are common in Australia, and they attack lilies. Characteristics of the larvae were dark grey with a longitudinal black line, a striking yellow line that runs along the middle of the dorsal, and a Y shape in the head. The female of S. picta lays eggs in groups ranging from 50 to 218 eggs per egg group with an egg size of 1 mm. Lili armyworm larvae have 5 stages with larval sizes of 2, 5, 15, 28, and 46 mm respectively. Meanwhile, the size of the pupa and imago of S. picta was 23 and 20 mm, respectively. The management of S. picta armyworms needs to be done so as not to cause major damage and losses to ornamental flower crops.

Abstract

The genus Graphium within the family Papilionidae comprises several species that exhibit morphological resemblance. Due to this criterion, their identification and discrimination through morphology is notably challenging. Therefore, in this study, we employed a length-based morphometric approach to reveal the ability of the characters to discriminate the five Graphium species that demonstrates the morphological resemblance; Graphium sarpedon, Graphium bathycles, Graphium doson, Graphium eurypylus, and Graphium evemon. The morphometric measurement of the total of 50 specimens was carried out by using seven characters measured from the wing and body regions. Multivariate statistical analyses such as Discriminant Function Analysis (DFA) and Cluster Analysis (CA) were utilized to assess the discriminatory ability of the morphometric data. While comparing between species, all morphometric characters were significantly different (p < 0.05). The results of DFA showed that two out of seven characters utilized have the lowest values of Partial’s Wilks Lambda; body length (1.165), and forewing length (1.183), therefore are suggested as the two most significant characters for the discrimination of the Graphium species. There are great overlapping patterns between the five species when plotting a scatter plot graph except for G. bathycles that formed nearly distinct group. In Cluster Analysis, G. sarpedon tends to be closer to G. evemon by having the lowest value of agglomeration (0.061). Our findings underscore the potential of length-based morphometric analysis as a supporting quantitative tool for resolving taxonomic ambiguities and enhancing species identification particularly within complex genera such as Graphium.

Abstract

The "fall armyworm," also known as Spodoptera frugiperda, is a maize pest that is native to North America. It invaded Africa in 2019 and caused serious economic damage, forcing the continent's nations to take swift action to protect off this new invading pest. In Egypt, a variety of chemical insecticides were promoted, but farmers quickly and repeatedly reported control failures. Fall armyworm samples were collected from five different maize-growing regions. Five widely available pesticide formulations: emamectin benzoate, chlorantraniliprole, indoxacarb, methomyl, and chlorpyriphos were tested under laboratory conditions against the 2nd and 4th instar larvae. The results demonstrated that S. frugiperda second-instar larvae were more vulnerable to all tested pesticides than fourth-instar larvae. Under laboratory circumstances, the LC50 values for the various substances were 0.090, 0.165, 0.243, 0.908, and 2.55 ppm, respectively. Furthermore, the insecticide emamectin benzoate was more effective than other pesticides. However, chlorpyriphos pesticide was the least harmful insecticide for controlling this bug. To determine how well these treatments perform against this pest, further trials are required.

Abstract

Insect pollinators are insects that play an important role in maintaining the existence of a plant species through pollination and maintaining the genetic diversity of plants in the population maintaining the existence of a plant species through pollination and maintaining the genetic diversity of plants in the population. Pollinator insects generally come from the Hymenoptera order. The purpose of this study was to determine the types of pollinator insect species that dominate coconut plantations in the Banyuasin area of South Sumatra. Data were collected by field observation using the plant survey method. The survey was conducted through direct observation of coconut plants owned by coconut farmers in the Banyuasin area. Observations were made on coconut plants by observing pollinator insect species that associate with flowers on coconut plants. Insect pollinator species found in coconut plantations in the Banyuasin area include Vespa affilish, Apis mellifera, and Apis dorsata. The most dominant type of pollinator insect found in coconut plantations in the Banyuasin area is Apis dorsata with 201 individuals. So, the results show that the abundance of individuals is high but has a low diversity index.

Abstract

Beetles (Insecta: Coleoptera) stands out as one of the most diverse insect groups, showcasing various color variations. These evolved color patterns present a fascinating trait crucial for understanding their evolution. However, studying these patterns poses challenges, given the intricate nature of colors in the natural world. While past researchers have explored beetle color patterns, quantifying colors requires costly equipment and sophisticated software. This paper introduces an alternative approach, utilizing digital images to examine color variability among Coleopterans. Forty-eight specimens from Mindanao, Philippines, were collected and photographed under consistent conditions. Subsequently, the images were calibrated and processed in R software to calculate image distances through cluster analysis. The results reveal that beetle color patterns fall into two categories: a dark color with deeper shades of gray and a moderately bright tone featuring a slight reddish hue with noticeable yellow highlights. Chrysochroa fulminans is the most distinct beetle across Coleopteran species due to its vibrant green coloration. Family-specific examination of color patterns revealed species with distinct color, Anomala flavipennis and A. smaragdina (Scarabaeidae), Otiorhynchus pauxillus (Curculionidae), Uloma culinaris (Tenebrionidae), and Nupserha fricator (Cerambycidae). The study's findings offer valuable insights into the evolution of Coleopterans, mainly their color patterns, serving as a valuable tool for classification.

Abstract

Mekarsari Fruit Park, situated in Bogor, boasts an extensive collection of 226 fruit species. Apart from vegetables and ornamentals, fruit plants play a significant role as hosts for whiteflies. Whitefly infestations can disrupt photosynthesis and respiration, affect the aesthetics of ornamental plants, and transmit plant diseases caused by viruses. The primary objective of this study was to assess the species diversity of whiteflies and their host ranges within Mekarsari Fruit Park. Purposive sampling was employed, followed by preparing collected samples for microscope slides and identification. A total of 20 whitefly species were collected from 56 fruit plant species spanning 20 different families. Of the 20 collected species, 16 were successfully identified, while four remained morphospecies. These whiteflies were categorized into two subfamilies: 17 species belonging to the Aleyrodinae subfamily and three species belonging to the Aleurodicinae subfamily. Paraleyrodes minei emerged as the most prevalent whitefly species, infesting 14 host plants across 11 families. Furthermore, the study revealed that 14 whitefly species were found exclusively on one fruit plant species, one whitefly species on two fruit plant species within the same family, and seven whitefly species on multiple fruit plant families. The Euphorbiaceae and Rubiaceae families were the most susceptible to whitefly infestation among the fruit plants.

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.
