Abstract

Continuous propagation of the fungus Beauveria bassiana on artificial media will cause a decrease in its virulence. The solution offered as an alternative to maintain the virulence of the B. bassiana fungus is the addition of chitosan to the growing medium with the right concentration. This study aims to determine the effect of the addition of chitosan at several concentrations on growth, development and virulence of B. bassiana. This research was designed using a completely randomized design with 6 treatments and 4 replications. The treatments used are P0 (control), P1 (chitosan 1 mg/ml), P2 (chitosan 2 mg/ml), P3 (chitosan 3 mg/ml), P4 (chitosan 4 mg/ml), and P5 (chitosan 5 mg/ml). The results showed that chitosan affected the growth and development of B. bassiana fungi, as seen in parameters of colony diameter and conidia viability. The highest colony diameter occurred in the P1 treatment that was 8.34 cm and the highest conidia viability also occurred in the P1 treatment which was 85.26%. The effect of chitosan on B. bassiana virulence can be seen in the parameters of mortality, mycosis, and mummification. The addition of a chitosan concentration of 1 mg/ml in the fungal growth medium has a good effect on the growth and virulence of B. bassiana.

Abstract

Pollinating insects act as agents for transferring pollen to the pistil that leads to the increase of quality seed production. Since carrot is propagation through seed, insect pollination are important in the reproduction of the crop. The purpose of this study was to observe the diversity and activity of pollinating insects on carrot flowers in the Experimental Garden of the Agricultural Technology Research and Assessment Installation (IP2TP) Berastagi. Scan sampling method was applied to record the pollinator diversity, while the foraging behaviour of the insects was observed using focal sampling. The number of insects were recorded, collected and preserved in ethanol 70%. Insect identification guideline book was used to identify the insects by comparing their morphology and physiology.  The results showed that there were 8 insect species visiting the carrot flowers: Apis mellifera Linnaeus, Polyrachis sp., Coccinella sp., Rhagonycha sp., Muscidae sp., Chrysomya sp., Nephrotoma sp. and Tabanus sp. A. mellifera was found to have the highest intensity visiting the carrot flowers (21.6 ± 10.06)% while the lowest was demonstrated by Polyrachis sp. (12.6 ± 4.12)%. Also, A. mellifera was recorded to be the most active insect (11.84 ± 1.46 seconds/flower) with the number of flowers visited was 5,06 ± 1,46 flowers/minute. Polyrachis sp. has been revealed to have the longest stay on the flowers visited (49.24 ± 3.89 seconds/flower) with the number of flowers visited 1.21 ± 3.90 flowers/minute. The diversity of pollinating insect was found to be in intermediate level (H’ = 1.89).

Abstract

Spodoptera frugiperda (J. E. Smith) is an invasive pest that causes a high economic impact on maize. Alternative control that is relatively safe to non-target organisms that can be combined with other control strategies is botanical insecticides. This study aimed to evaluate the effect of Azadirachta indica (Meliaceae), Ricinus communis (Euphorbiaceae) oils, and their mixtures on mortality and nutritional indices and oviposition of S. frugiperda. The testing of toxicity and nutritional indices was done using the feed dipping method, while oviposition testing was conducted by spraying on treated plants. The relationship between concentration and mortality of tested insects was analyzed using probit analysis, while other data using analysis of variance. The results showed that A. indica, R. communis, and their mixtures were toxic to S. frugiperda larvae (II–VI) with LC50 values ​​of 0.039 (0.017–0.100)%, 0.144 (0.094–0.221)%, 0.034 (0.021–0.061)% respectively, and of LC95, 0.391 (0.134–16.671)%, 4.379 (1.986–15.516)%, 0.219 (0.104–1.251)%, respectively. The toxicity of the oil mixture increased 4.2 times to 20.0 times at LC50 and LC95, respectively. Oil treatments resulted in a decrease in the relative consumption rate, relative growth rate, food utilization efficiency, an increase in approximate digestibility of S. frugiperda. In addition, botanical oils act as antioviposition of S. frugiperda. However, A. indica, R. communis, and their mixtures were phytotoxic on maize. Therefore, the opportunity of a mixture of A. indica and R. communis oils to be used as an insecticide still needs to be evaluated or can be used on other plants that are more tolerant.

Abstract

The beetle Tenebrio molitor has potential as a plastic decomposer. Plastic can also be degraded by exposure to sunlight. The aim of this research was to determine the feeding behavior and biological responses of T. molitor exposed to various type of plastics. Seven types of plastics, namely bioplastics (Bio), expanded styrofoam (EPS), oxo-biodegradable (Oxo), three plastics Bio-P, EPS-P, Oxo-P that had been exposed to sunlight, and controls contained a mixed pollard-carrots slices were tested on four days-old of adult T. molitor. The choice feeding method was carried out at day and night by releasing 200 and 300 beetles in the middle of a ±15 cm diameter petri dish divided into 7 radial spaces, and their movement were observed within 24 hours. The forced feeding method for observing biological responses was carried out by releasing 10 male and female beetles in a petri dish as described above. The results showed that around 32–39% of the beetle population visited most of the pollard feed. In the feed treatment without pollard, 20% of the beetles chose EPS, EPS-P and Bio. Beetles survived 23 and 40 days on Bio and Bio-P feed, respectively. Egg production by the beetles exposed to the Bio and Bio-P diets was 2 and 3 eggs/female/10 days. Around 85% of pollard feed consumed contributed to 5% of body weight gain. About 58–64% of Bio, Bio-P, EPS, EPS-P and 6–12% Oxo, Oxo-P feeds were successfully consumed. The decrease in its body weight occurred in all plastic feed treatments ranging from 13–28%.

Abstract

The coconut rhinoceros beetle (Oryctes rhinoceros L.) and brown rhinoceros beetle (Xylotrupes gideon L.) (Coleoptera: Scarabaeidae) are insect pests commonly found in oil palm plantations. Availability of breeding sites is one of factors that can increase the beetle population. Therefore, this study aimed to determine the abundance and age structure of the coconut rhinoceros beetles and brown rhinoceros beetles in the breeding sites located in a plantation with immature and mature stage of oil palms. The results of this study indicated that the abundance of coconut rhinoceros beetle was found to be lower than brown rhinoceros beetle (4.47±13.56 compared to 25.23±16.48 individuals/plot) in the oil palm plantations in PTPN VIII Parakan Salak, Sukabumi Regency. The population of coconut rhinoceros beetle was found in the breeding site located in the plantation with mature oil palms, but not found in the location with immature plants. The age structure of coconut rhinoceros beetle was dominated by the 1st and 2nd instar larvae. The age structures of brown rhinoceros beetles in the breeding sites located in the immature and mature oil palm were similar, and they were dominated by the 1st, 2nd, and 3rd instar larvae. Results of correlation analysis show that there is no correlation between soil chemical characteristics of the breeding site and the beetle population. Soil chemical characteristics at the breeding sites in both locations were relatively similar, and consequently, the abundance and age structure of coconut rhinoceros beetle and brown rhinoceros beetle not significantly different between both locations.

Abstract

Human activities may influence the diversity of aquatic insects in rivers. This study aims to assess the diversity of aquatic insects and their relation with mercury levels and water quality along rivers located near the gold mine in Poboya, Central Sulawesi. The insects were collected at six locations based on human activity levels. At each site, the mercury level of water was measured using atomic absorption spectrophotometry (AAS). In addition, water temperature, acidity, dissolved oxygen, and total dissolved solids were determined. The study recorded 23 species of aquatic insects belonging to 7 orders and 14 families. Mercury levels in the rivers did not exceed the threshold except at two sites and did not affect aquatic insects’ diversity. The diversity of aquatic insects, however, tends to decrease downstream. The diversity of aquatic insects, particularly the Ephemeroptera, Plecoptera, and Trichoptera orders, tended to be higher at the higher dissolved oxygen sites.

Abstract

The greater wax moth (Galleria mellonella (Linnaeus)) is one of Asia’s most essential pests in honey beekeeping. Apart from being a pest, G. mellonella was also used as a test insect in several business fields. The needs of the population of G. mellonella encourage several areas of the business to cultivate it practically and economically. This study aimed to determine and examine the composition of food ingredients as an artificial diet that can affect the growth and development of G. mellonella. The test consisted of four different feed-modified formulas, namely P1 (corn flour, wheat, glycerol, and yeast), P2 (rice flour, wheat flour, wheat bran, glycerol, and yeast), P3 (wheat flour, wheat, glycerol, and yeast), and P4 (brown rice, glycerol, and yeast). The observation criteria were life cycle, mortality rate, fecundity, and egg fertility of the G. mellonella moth. Based on the study’s results, the life cycle development of G. mellonella was the shortest in the P3 treatment (71.5 ± 5.2 days) and the longest P4 treatment (84.2 ± 8.3 days). The highest mortality rate was in the P3 feed type at 13.12%, while the lowest occurred in the P4 treatment at 4.44%. Based on the fecundity of female imago, treatment P4 had the highest fecundity level of 527.7 eggs/female, while treatment P1 was the lowest (169.6 eggs/female). P4 treatment responded best to several biological aspects of the G. mellonella moth, such as larger body size, lower mortality, and high fecundity rates.

Abstract

Insect populations have declined significantly over the last few decades. Anthropogenic factors such as deforestation, land-use change, climate change, and pesticides play a major role in insect population decline. In addition to those factors, insects also face challenges from air, noise, and light pollution derived from human activities. Light pollution in the form of artificial light at night (ALAN) is generally known to be one of the factors driving insect declines but it has rarely been studied in Indonesia. In this literature review, we collected empirical evidence from previous studies to provide a comprehensive report on the impact of ALAN on insects. Most studies demonstrate a decline in insect populations in areas with high ALAN intensity, such as urban areas. Furthermore, ALAN was reported to disrupt insect visual systems, which results in disturbances to predator avoidance and foraging movements. Until now, most work related to artificial light in Indonesia have focused on light as a method of controlling pests. Hence, studies related to artificial light as a pollutant are urgently needed to increase our understanding of the effects of ALAN on the survival of organisms, especially insects. Future research must seek suitable solutions to create environmentally and ecologically friendly conditions for various organisms, especially those susceptible to the negative effects of light, such as insects.
