“…Minyak mimba memiliki senyawa aktif azadirakhtin dan salanin yang dapat berfungsi sebagai antifeedant. Larva yang terpapar senyawa antifeedant tersebut menyebabkan aktifitas makannya menurun, sehingga larva akan kekurangan nutrisi yang diperlukan dalam proses pertumbuhan larva akibatnya pertumbuhan akan terhambat dan bobot tubuhnya menjadi lebih rendah (Ramadhan et al, 2016 40,27 ± 8,46 a 1:1 (Mimba : Cengkeh) 0,25% 27,87 ± 9,21 b 1:1 (Mimba : Cengkeh) 0,5% 17,25 ± 0,69 c 1:1 (Mimba : Cengkeh) 1%…”

Crocidolomia pavonana is one of the important pest in Brassicaceae family. The used of botanical pesticides such as neem and clove can be used as alternative control for C. pavonana. This study aimed to examine the effect of neem oil, clove oil, and its mixture to C. pavonana. This experiment was conducted from November 2019 to May 2020 at the Laboratory Pesticides and Environmental Toxicology of the Department of Plant Pests and Diseases of the Faculty of Agriculture, Universitas Padjadjaran. The experimental method used in this research was Randomized Block Design with 21 treatments, i.e control, neem oil, clove oil, and its mixture at concentrations of 0,1%, 0,25%, 0,5%, and 1%, each treatments was replicated 3 times. The result of this experiment showed that single or mixed treatments (Neem : Clove) at consentration of 1% caused 100% larvae mortality. Mixed treatment at ratio 1:1 could inhibits the formation of pupa and imago, and could prolong the development time of larvae in instar II-III and instar II-IV. In addition, mixed treatment at ratio 2:1 was also prolong the development time of larvae in instar II-pupa, reduce food consumption, inhibit the formation of imago, and reduce the number of eggs C. pavonana.

“…The test method used is the residue on the feed leaves. Two pieces of fresh maize leaves (4 cm x 4 cm) and free of insecticide were dipped into the extract preparation according to the treatment, the commercial insecticide of emamectin benzoate, and the control, then drained and put into a Petri dish (9 cm diameter) that lined with tissue and infests 10 FAW first-instar larvae [14]. Leaves assays in treatment, comparison, and control were tested for 48 hours, then those leaves were replaced with fresh leaves without treatment [4,15].…”

Fall armyworm (FAW) Spodoptera frugiperda is an important pest on maize. One of the environmentally friendly control strategies of FAW is by utilizing botanical insecticides. Extracts of Syzygium aromaticum, Annona muricata, and Piper retrofractum are known to be able to control various types of insect pests and ensure sustainability in farming. The objective of this research was to study the effective control of three plant extracts against FAW, including the toxicity against larvae using leaf residual method, the feeding inhibition against larvae, and the oviposition deterrence against female. Probit analysis was used to estimate LC50 and LC95 values of the extracts. The extract of P. retrofractrum exhibited highest mortality compared to the other extracts with LC95 values of 0.230%, followed by S. aromaticum 0.349%, then A. muricata 1.387% against first-instar larvae at 96 hours. P. retrofractum extract showed the highest feeding inhibition of 90.14% at LC95 value, which gradually decreased on S. aromaticum and A. muricata extracts were 80.33% and 78.44%, respectively. Three plant extracts at LC99 and 2 x LC99 levels deterred female oviposition by 100%. This results indicate that P. retrofractum extract has great potential for further development as a botanical insecticide to controlling FAW.

“…Table 2 showed a decrease in feed consumption after treated with entomopathogenic fungi. According to Ramadhan et al (2016), decrease in feed consumption resulted in larvae lacking the nutrients needed to support larval growth, so that larval growth was retarded.…”

Spodoptera frugiperda is a new pest in Indonesia that attacks corn and can cause up to 100 percent damageon young plants. As an invasive pest, information on potential indigenous natural enemies that cancontrol this pest is needed. This study aims to determine the effectiveness of indigenous entomopathogenic fungi and their application methods on mortality, feeding activity, growth, fecundity, and fertility of S. frugiperda. This study used a factorial Completely Randomized Block Design (RCBD) method consisting of 10 treatments. Treatmentstested werecombination of fungi species, namely Fusarium sp., Aspergillus oryzae, Entomophthora sp. with conidia density 109 ml-1, distilled water and cypermethrin at concentration of 1 ml.L-1 as a control. Two application techniques used were direct application on S. frugiperda larvae and diet test. Each treatment was repeated three times resulting in30 experimental units. Variables observed included mortality, feeding activity, growth, fecundity, and fertility of S. frugiperda. Results showed that the three fungi and cypermethrin treatment did not cause mortality, but reduced feeding activity, fecundity and fertility of S. frugiperda. Application of entomopathogenic fungi ondietswas more effective than directly spraying S. frugiperda larvae. The best treatment combination that suppressed feeding activity was the application of Aspergillus oryzae sprayed on S. frugiperda diet.It was also suspected that S. frugiperda larvae used in this test had developed resistance to cypermethrin.
