Abstract

Leafminers, Liriomyza huidobrensis (Blanchard) (Diptera: Agromyzidae) known as main pest at vegetable and ornamental crop. Hemiptarsinus varicornis (Girault) (Hymenoptera: Eulophidae) is one of ectoparasitoid larvae of L. huidobrensis that usually find in the field, however the levels of parasitism at field relative lower. Therefore we need the conservation technology of parasitoid in order to its population overflow so that its performance increases. Rorippa indica (L) have potential as reservoir of parasitoid H. varicornis, so that can be used as conservation medium of H. varicornis. Planting weeds R. indica among of chickpea crop, can decraese the population of adult and larvae L. huidobrensis significantly, increase adult population H. varicornis and larvae population L. huidobrensis parasitism by H. varicornis. Growth rate of population adult H. varicornis at block without weeds R. indica follow the pattern of regretion equation Y=0,1312X?0,2246 and Y=0,7172X+1,1 while at the block planted weeds R. indica. Growth rate of larvae population L. huidobrensis at block without weeds R. indica follow the pattern of regretion equation Y=0,9315X?0,9835 and Y=0,8647X+1,0875 while at the block planted weeds R. indica.

Abstract

Characteristics and Toxicity of Nanoemulsion Formulations of Piper retrofractum and Tagetes erecta Extract Mixtures. Nanotechnology has been used in the developing of botanical insecticide formulation for improving its stability and effectiveness. The research was aimed to make nanoemulsion formulations of Piper retrofractum fruits and Tagetes erecta flowers extracts and to evaluate their toxicity against brown planthopper (Nilaparvata lugens [Stål]) nymphs. The development of nanoemulsion formulaions was carried out by using the low energy method with inversion phase emulsification.  The toxicity of the four formulations was tested against brown planthopper nymphs using a contact method. Four nanoemulsion formulations were obtained.  The study showed that in the developing of the formulations, the type and level of emulsifier materials affected the physical characteristics of formulas, such as stability, surface tension, viscosity, particle size, and particle morphology. The nanoemulsion formulation containing 1% of the mixture of P. retrofractum fruits and T. erecta flowers extracts, 1.75% Triton X-100 emulsifier showed the highest toxic on the brown planthopper nymph, with the LC95 value was 0.15%.  The study indicates that nanoemulsion formulation of P. retrofractum and T. erecta extracts are potential to be developed as botanical insecticide to control brown planthopper of rice.

Abstract

Spodoptera frugiperda is a major pest that attacks food and horticultural crops. The development of botanical pesticides in nanoemulsion form is one strategy to manage this pest. This research aimed to analyse the properties and effectiveness of nanoemulsions formulated using phase inversion and homogenization methods from Leucaena leucocephala and Annona muricata seed extracts against S. frugiperda. The research methods included mass rearing of S. frugiperda, extraction of L. leucocephala and A. muricata seeds, nanoemulsion formulation, and characterization of nanoemulsion properties. The results showed that the phase inversion method produced larger particle sizes compared to the homogenization method. Similarly, the phase inversion method resulted in a wider particle size distribution, while homogenization produced more uniform droplets. The nanoemulsion of the mixed extract of L. leucocephala and A. muricata seeds formulated using the homogenization method provided an antifeedant effect of 56.15% (medium inhibition criteria). The lowest antifeedant activity was observed in nanoemulsion from L. leucocephala using the phase inversion method (36.87%, low inhibition criteria). The highest ovicidal effect (72.93%) was also obtained from the mixed-seed nanoemulsion prepared by homogenization.

Abstract

Fall armyworm (Spodoptera frugiperda J.E Smith) is a major invasive pest that threatens maize production in Indonesia. This study aimed to evaluate the activity of nanoemulsions of citronella and garlic essential oils, both individually and in combinations at ratios of 1:1, 2:1, and 1:2, against third-instar larvae of S. frugiperda. The essential oils were obtained by steam distillation and formulated into nanoemulsions using Tween 80. Toxicity was assessed via contact assays and analyzed with POLO-PC software to determine LC50 and LC95 values. The citronella–garlic ratio of 2:1 was the most promising, yielding the lowest LC50 (0.1 % at 96 hours) and consistently exhibiting strong synergistic effects at the LC50 level compared with the 1:1 and 1:2 ratios, which more frequently showed additive or antagonistic interactions. The citronella nanoemulsion displayed the smallest particle size (97.8 nm) but the highest polydispersity index (PI) (0.406), indicating lower physical stability. In contrast, the garlic nanoemulsion exhibited a particle size of 185.9 nm with a PI of 0.270, reflecting a more stable system. The citronella–garlic combination at a 2:1 ratio produced the largest particle size (204.9 nm) but the lowest PI (0.239), suggesting superior stability and a more uniform particle distribution. These findings support the potential of nanoemulsified essential oils as eco-friendly botanical insecticides.
