Abstract

Cassava is one of the food commodities in Indonesia, but its productivity often decreases due to mealybug attacks (Hemiptera: Pseudococcidae). This study aims to determine the type and abundance of mealybugs and the ecological relationships between them and their natural enemies on cassava plants. The sampling method employed was purposive sampling, involving the selection of 100 sample plants per location, namely Benteng Village and Pasirlaya Village, in Bogor Regency. Mealybug and parasitoid samples were taken from three infested leaves, while predators were collected from the plant canopy. Identification was carried out morphologically to the species level, analyzed using the ecological index, and compared using the Mann-Whitney test (P = 0.05). The study’s results identified four species of mealybugs: Paracoccus marginatus Williams & Granara de Willink, Ferrisia virgata (Cockerell), Pseudococcus jackbeardsleyi (Gimpel & Miller), and Phenacoccus manihoti Matile-Ferrero. Natural enemies of mealybugs found from the predator group were Cryptolaemus montrouzieri Mulsant, Plesiochrysa ramburi (Schneider), Scymnus sp.1, Scymnus sp.2, Theridion sp., and from the parasitoid group, namely Anagyrus lopezi (De Santis), Acerophagus papayae Noyes & Schauff. The diversity, evenness, and richness indices of arthropod species were higher in Pasirlaya, while dominance was higher in Benteng. The parasitization rate of A. papayae and A. lopezi was more stable in Pasirlaya, although the arthropod population did not differ significantly between locations (P = 0,31). This study concluded that Pa. marginatus and Ph. manihoti were the dominant mealybug species, with predators Theridion sp. and C. montrouzieri as the most abundant natural enemies, The parasitoid A. lopezi was known to parasitize Ph. manihoti, and A. papayae parasitized Pa. marginatus.

Abstract

Erionota thrax Linnaeus (Lepidoptera: Hesperiidae) is an insect that actively attacks banana plants during the vegetative phase, particularly when new leaves begin to grow. Damage caused by E. thrax infestations can reach up to 63.14%, which falls into the category of severe damage. The use of the egg parasitoid Ooencyrtus erionotae Ferriere (Hymenoptera: Encyrtidae) is one of the methods to reduce the population of E. thrax in the field. This study aimed to examine the potential for parasitoid reproduction through the study of life cycle, demographic parameters, sex ratio, parasitization rate, and adult behavior. The research was conducted at the Laboratory of Parasitoid and Predator Bioecology, Department of Plant Protection, Faculty of Agriculture, IPB University, and at the Cikabayan Experimental Farm. The test insects were reared on host plants for breeding, and their life cycle and development were observed. Tests on the insects included adult longevity, parasitoid reproduction, and parasitism in the field. The data obtained were analyzed using analysis of variance (ANOVA), followed by Duncan’s multiple range test. The results showed that the life cycle of O. erionotae is relatively short, ranging from 13 to 15 days. The intrinsic rate of increase (r) for O. erionotae was 0.29 per day. The sex ratio (male:female) of O. erionotae in both laboratory and field conditions was female-biased, at 1:3.56. In the field, the parasitism rate of O. erionotae ranged from 16.5% to 48.67%. Based on its biological characteristics, demographic parameters, and field parasitism rates ranging from 16.5% to 48.67%, O. erionotae shows great potential for use as a biological control agent against the banana leaf roller pest E. thrax.

Abstract

Tetragonula laeviceps Smith are widely found and cultivated in Indonesia. They play a crucial role in providing ecological services as pollinators of plants. However, there has been a global concern of bees’ population decline, which may be attributed to the intensive use of insecticides. This study aimed to analyze the toxicity level of several insecticide active ingredients and the effects of insecticide exposure on the physiology of T. laeviceps. Four insecticides active ingredients, carbosulfan, clothianidin, diafenthiuron, and tetraniliprole were tested for toxicity against T. laeviceps through dermal and oral exposures at five concentration levels. Bee preference testing was conducted through olfactory tests using a Y-tube olfactometer. Results showed that insecticide exposure affected the visitation length of T. laeviceps (P = 0.006), but not its visitation frequency (P = 0.286). Carbosulfan and clothianidin were toxic to T. laeviceps, both dermally (LC50 31.28 and 0.09 ppm, respectively) and orally (LC50 28.51 and 0.41 ppm, respectively). Meanwhile, diafentiuron and tetraniliprole were more harmful to bees during dermal exposure (LC50 7,882 and 148.81 ppm, respectively) compared to oral exposure (LC50 53,983 and 5,240 ppm, respectively). The toxicity levels of the insecticides carbosulfan and clothianidin are classified as highly toxic and harmful, while diafentiuron and tetraniliprole are not harmful to T. laeviceps bees. In addition, the capability of bees to consume feed was also significantly decreased due to exposure to carbosulfan (10,000 and 3,000 ppm) and clothianidin (300; 30; 3; 0,3; and 0,03 ppm) insecticides. Information of the toxicity levels and effects of various insecticides on bees may contribute to the development of insecticide management to keep the survival of bees in agricultural areas.

Abstract

Culex quinquefasciatus (Say) (Diptera: Culicidae)  is a primary vector of lymphatic filariasis and various encephalitis viruses, posing significant public health threats. Optimizing mass-rearing protocols for this mosquito species, particularly through improved nutritional strategies, is crucial for enhancing vector control effectiveness and efficiency. This study evaluates the effects of larval diet composition and adult sugar diet on the development and survivability of C. quinquefasciatus. Larvae were fed five diets based on combinations of protein-rich dog food (DF) and carbohydrate-rich rice flour (RF): 100% DF, 100% RF, DF:RF (3:1), DF:RF (1:1), and DF:RF (1:3). Adult mosquitoes were provided with 10% sucrose, 10% dextrose, or 10% honey. Observed parameters included larval and pupal morphometry, pupation time and rate, adult wing length, and adult survival over 50 days. The results showed that the DF:RF (1:1) diet yielded optimal larval length, pupation rate, and adult female wing length, whereas the DF:RF (3:1) diet resulted in the shortest pupation time and largest larval width. The combination of the DF:RF (1:1) diet and honey was the most effective in promoting adult development and survival. These findings provide valuable insights for optimizing mass-rearing protocols, which are essential for research and vector control programs.

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

Zoonotic malaria is an emerging public health issue in Indonesia, particularly in regions with significant forest cover and frequent interaction between humans and non-human primates. Information regarding the diversity and behaviour of mosquito vectors in these areas is very limited. This study aims to identify the diversity and bionomics of mosquitoes, particularly Anopheles sp., across five ecologically diverse locations in Palangkaraya, Central Kalimantan, to gain an understanding of their potential role in zoonotic malaria transmission. Cross-sectional entomological surveys were conducted during November 2022 (during the rainy season) and October 2024 (at the beginning of the rainy season). Adult mosquitoes were collected using human landing catches (HLC) from 18:00 to 06:00, and larval habitats were surveyed and characterized following the WHO protocol. A total of 1,278 mosquitoes were collected from six genera, with Anopheles letifer Sandosham dominating the Anopheles group (97%), particularly in swampy secondary forests, such as Nyaru Menteng. This species exhibited peak outdoor biting activity shortly after dusk and late at night, posing a greater risk to those outside or in unscreened homes. Larval surveys conducted at 48 sites revealed Anopheles larvae in 27% of habitats, predominantly in swamps (67% positive). Although no significant associations were found with environmental factors, natural and semi-natural water bodies appear key to sustaining vector populations. These findings highlight the ecological flexibility of An. letifer and its potential impact on zoonotic malaria transmission in forest-edge communities. Vector control strategies should include integrated methods, such as larval source management and community-based interventions, particularly in peat swamp regions where interactions between humans and non-human primates are frequent.
