The nettle caterpillar, Setothosea asigna, is a major pest in an oil palm plantation in North Sumatra, which causes severe defoliation and reduces productivity. Controlling this pest commonly uses Pyrethroids insecticides, but dimehypo was also used when controlling bagworms and nettle caterpillars in the exact location. The sublethal doses were reported to decrease pest mortality. The study aimed to determine the effect of dimehypo sublethal doses on mortality and pupae acceleration of Setothosea asigna. This study used five doses of treatments using the fogging technique, i.e., 50, 100, 150, 200, and 250 ml/ha, and untreated were tested following a completely randomized design (CRD) with five replications. The results showed that the sublethal doses (50, 100, 150, and 200 ml/ha) had low mortality reached 58.33-62.50%, and the efficacy value reached 52.38-57.14% in seven days after application. The lethal dose (250 ml/ha) has 100% mortality seven days after application, and the efficacy value reaches 80.95% in five days. The sublethal doses of 50, 100, and 150 ml/ha showed an acceleration in the Setothosea asigna pupation on three days and doses of 200 ml/ha on five days from the untreated treatment. This founding could be the reason for Setothosea asigna’s overlapping populations and prolonged the pest outbreak.

“…Ref. [17] reports that sub-lethal dosing can cause insect physiological disturbances. Probit analysis of test larval mortality data showed LC50 and LC95 values of 0.068% and 0.151% with a regression slope of 4.749.…”

“…As a result, the growth and development of larvae become inhibited. [17] concluded that giving sub-lethal (non-lethal) concentrations in insects can affect insect biological activity in the form of a length of development, length of life, and size of larvae and pupae, in addition to feeding activities. Sub-lethal dosing is expected to reduce pest populations in the next generation due to the development of imperfect biological activity.…”

Spiked pepper (Piper aduncum) essential oil has the potency to develop as a botanical insecticide in controlling fall armyworm (Spodoptera frugiperda). This study aimed to determine the activity of spiked pepper fruit essential oils against fall armyworm larvae. This study was held from November 2020 to March 2021 at the Insect Bioecology Laboratory, Faculty of Agriculture, Andalas University, West Sumatera, Indonesia. The experiment used a Completely Randomized Design (CRD), including preliminary and advanced tests. The preliminary test was conducted using three concentration levels (0%, 0.25%, and 0.5%) and consisted of 4 replications. The advanced test was conducted using 5 concentration levels and control (0%, 0.05%, 0.07%, 0.11%, 0.17% and 0.25%) and consisted of 5 replications. The test ran with the leaf-dipped method, with parameters observed were larval mortality, feeding inhibition activity (antifeedant), and larval development time. The observation data were analyzed using analysis of variance, and if there were any significant differences, it continued with a further test using Least Significant Difference (LSD) at a 5% level. LC50 and LC95 values were analyzed using the POLO PC software. The result showed that spiked pepper fruit essential oil could cause larval mortality, inhibit feeding activity, and inhibit Fall armyworm larval growth. The treatment with a concentration of 0.17% showed the best result, which could lead to 98.67% larvae mortality, inhibit feeding activity by 91.23% and inhibit larvae growth from reaching the sixth instar around 3.26 days compared to the control. The LC50 and LC95 value of spiked pepper fruit essential oil solution was 0.068% and 0.151%, respectively. Overall, spiked pepper essential oil has insecticidal activity against fall armyworm larvae.

Insecticides are widely used to boost crop yields, but their effects on non-target insects like Vespa magnifica are still poorly understood. Despite its ecological and economic significance, Vespa magnifica has been largely neglected in risk assessments. This study employed physiological, biochemical, and transcriptomic analyses to investigate the impact of sublethal concentrations of thiamethoxam, avermectin, chlorfenapyr, and β-cypermethrin on Vespa magnifica. Although larval survival rates remained unchanged, both pupation and fledge rates were significantly reduced. Enzymatic assays indicated an upregulation of superoxide dismutase and catalase activity alongside a suppression of peroxidase under insecticide stress. Transcriptomic analysis revealed increased adenosine triphosphate-related processes and mitochondrial electron transport activity, suggesting elevated energy expenditure to counter insecticide exposure, potentially impairing essential functions like flight, hunting, and immune response. The enrichment of pathways such as glycolysis, hypoxia-inducible factor signaling, and cholinergic synaptic metabolism under insecticide stress highlights the complexity of the molecular response with notable effects on learning, memory, and detoxification processes. These findings underscore the broader ecological risks of insecticide exposure to non-target insects and highlight the need for further research into the long-term effects of newer insecticides along with the development of strategies to safeguard beneficial insect populations.
