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

Lemons are plant horticulture fruits which kind of oranges are also known as designation citrus. The fruit shaped as a round oval, colored yellow bright, and tasteful sour or a little sweet. Other roles of insects in nature besides insect potential herbivores (phytophagous) pests, that is, as predators and parasitoids. The study aims to identify types and diversity of enemy potential natural (predators and parasitoids). as controller pests on lemon plants. The study carried out on land lemons in Namo Terasi village, Sei Bingai District, Langkat Regency. Identification insects was done in Laboratory Pests, Faculty of Agriculture, University of Sumatera Utara which held on month, March until June 2023. This study uses a purposive sampling method with 5 types, such as yellow sticky trap, red trap, black trap, blue ball trap, and net trap. Total insects identified on the lemon’s vegetation (Citrus lemon) consist of 10 Orders, 38 Families and 49 Genera, and 2308 individuals. The highest population recorded from Aphidius (Hymenoptera: Braconidae) as many as 481 individuals. The highest of Density and Relative Density from family Braconidae (D=481, RD=21.02%), whereas the lowest of Mantidae Family (D= 3, RD=0.13%).

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.
