Collard greens are commonly grown in family farming systems; however, damage caused by the diamondback moth Plutella xylostella (Lepidoptera: Plutellidae) reduces yields, leading to successive applications of insecticides and consequently, environmental and toxicological problems. Therefore, it is essential to search for alternatives that reduce the use of pesticides and are economically viable and accessible to small farmers. This study was aimed at evaluating the insecticidal activity of aqueous extracts of neem and tobacco on P. xylostella. First instar caterpillars were offered collard leaf discs treated with different concentrations (30 caterpillars per treatment) and after the third day, mortality was evaluated. To evaluate ovicidal properties, collard leaves with 30 eggs were immersed in extracts and after 48 h, viability was measured. Oviposition deterrent activity was assessed with 23 couples of P. xylostella released in cages (repetitions) containing treated collard plants and after 48 h, the number of eggs per plant was recorded. Neem and tobacco extracts exhibited larvicidal, ovicidal, and oviposition deterrent properties against P. xylostella, indicating that the use of these extracts may be promising alternatives in family farming systems.

<p><em>Plutella xylostella</em> is one of cabbage’s main pests. Botanical insecticides as alternative of chemical insecticides need to be expand, one of them is mahogany seed extract. Mahogany seed exctract contains saponin and flavonoid as reported mortal to <em>P. xylostella</em>. This study aimed to know the effective concentration of mahogany seed extract to manage <em>P. xylostella</em> different larva instar and to know LC<sub>50 </sub>value of mahogany seed extract to <em>P. xylostella</em>. This method used was completely randomized experimental design (CRD). Two factors used were mahogany seed exctract concentrations (0 gL<sup>-1</sup>, 5 gL<sup>-1</sup>, 10 gL<sup>-1</sup>, 20 gL<sup>-1</sup>, and 40 gL<sup>-1</sup>) and larva instar (first and third instar). Each treatment repeated four times. The results showed that percentage of larva mortality first instar higher than third instar. Concentration 20 gL<sup>-1</sup> of mahogany seed exctract effective to kill first instar larva, and concentration 40 gL<sup>-1</sup> effective for third instar. Percentage of pupa mortality highest in concentration 10 gL<sup>-1</sup> for first instar and concentration 40 gL<sup>-1</sup> for third instar larva. Antifeedant increased as concentration given, while the eating ability that higher in third instar was decreased. LC<sub>50</sub> for first instar larva was 2,6 gL<sup>-1</sup> and third instar was 13,7 gL<sup>-1</sup>, meaned that mahogany seed extract more toxic to first instar than third instar larva.</p>

UJI DAYA BUNUH EKSTRAK BIJI SIRSAK (Annona muricata) TERHADAP  LARVA KUBIS  Plutella xylostella (Linn.) (LEPIDOPTERA: PLUTELLIDAE) ABSTRAK Penelitian terhadap uji daya bunuh ekstrak biji sirsak (Annona muricata) terhadap larva kubis Plutella xylostella dilakukan untuk mengetahui uji daya bunuh beberapa konsentrasi ekstrak biji sirsak terhadap larva Plutella xylostella. Manfaat penelitian adalah untuk memberikan informasi daya bunuh dari ekstrak biji sirsak terhadap larva P. xylostella sehingga dapat digunakan dalam pengendalian hama tersebut.  Penelitian dilaksanakan di desa Rurukan Kota Tomohon, yang berlangsung selama 3 bulan. Metode penelitian yang digunakan adalah Rancangan Acak Lengkap (RAL), yang terdiri dari 6 perlakuan dan tiap perlakuan terdiri dari tiga ulangan.        Hasil penelitian menunjukkan bahwa persentase kematian larva meningkat seiring dengan meningkatnya konsentrasi ekstrak biji sirsak yang disemprotkan yaitu 10 g/l, 20 g/l, 30 g/l, 40 g/l dan 50 g/l. Beberapa larva yang belum mati pada stadia ini dan masih hidup hingga pada stadia pupa, persentase mortalitasnya tidak meningkat seiring dengan meningkatnya konsentrasi ekstrak biji sirsak yang diaplikasikan, yakni secara berurutan 30g/l (11,11%), 10g/l (13,33%), 50g/l (14,44%), 20g/l (16,67%) dan 40g/l(16,67%). Total persentase mortalitas larva dan pupa meningkat seiring dengan meningkatnya konsentrasi ekstrak biji sirsak yang disemprotkan. Konsentrasi ekstrak biji sirsak sebesar 50g/l sudah cukup baik digunakan sebagai insektisida botani dalam mengendalikan populasi hama P. xylostella, karena pada konsentrasi ini efektif mematikan sebesar 96,78% populasi serangga yang diuji. Kata kunci: biji sirsak, Plutella xylostella, kubis   TEST POWER KILL THE SEED EXTRACT SOURSOP (Annona muricata) ON CABBAGE LARVAE Plutella xylostella (Linn.) (LEPIDOPTERA: PLUTELLIDAE) ABSTRACT Research on the test of the power to kill the seed extract of soursop (Annona muricata) to larvae of the cabbage Plutella xylostella test is performed to determine the power to kill some seed extract concentration of soursop against Plutella xylostella larvae. Benefits of the research is to provide information on the killing power of soursop seed extract against P. xylostella larvae so that it can be used. In the pest control.  Research conducted at the village Rurukan Tomohon, which lasted for three months. The method used is Completely Random Design (CRD), which consists of 6 treatments and each treatment consisted of three replication.  The results showed that the percentage of larval mortality increases with increasing concentration of soursop seed extract that is sprayed is 10 g / l, 20 g / l, 30 g / l, 40 g / l and 50 g / l. Some larvae are not dead at this stage and still live up to the pupal stage, the percentage of mortality was not increased with increasing concentration of soursop seed extract is applied, ie sequentially 30g / l (11.11%), 10g / l (13.33 %), 50g / l (14.44%), 20g / l (16.67%) and 40g / l (16.67%). Total percentage mortality of larvae and pupae increased with increasing concentration of soursop seed extract is sprayed. Concentration of soursop seed extract of 50g / l is good enough to use as a botanical insecticide to control the pest population of P. xylostella, because at this concentration amounted to 96.78% effective lethal insect populations tested. Keywords: soursop seed, Plutella xylostella, cabbage.

Insecticidal properties of fractioned extracts from Pangium edule Reinw seed and Annona muricata seed against Plutella xylostella larvae were investigated in the laboratory. The study was initiated to investigate the possibility of using botanical pesticides to control P.xylostella, a serious cosmopolitan pest of crucifer plants. The study aims to determine the most effective concentration and the most active extract;  to evaluate the different extract concentrations on the treated larvae; and to characterize the phytochemical contents of the most effective extracts fraction. The study was an experiment initiated by test of phytochemical screening test in order to discover the presence of secondary metabolites in the extracts. It was followed by the test of mortality of the diamondback moth larvae. Furthermore, the extracts hexane fraction and etanol fraction, were conducted with completely randomized design; The LC50 values were determined following probit analysis, the data were treated in the software programme IBM Statistic SPSS 20. Results showed that n-hexane fraction is the most effective againts larvae (LC50-48h = 12,71 mg/L) from P.edule seed extract, (LC50-48h = 50,81 mg/L) from A.muricata seed extract. Larva mortality was highest using 1000 ppm n-hexane fraction (96,6%) derived from P.edule seed extract, (93,3%) derived from A.muricata seed extract. The ethanol fraction tested positive for alkaloid, saponins, flavonoids, terpenoids, phenol and tannins. N-hexane fraction of P.edule seed extract, and A.muricata seed extract are an effective botanical insecticides exhibiting larvicidal and antifeedant properties against P.xylostella thus it can be alternative to synthethic insecticides. Results indicate that these botanical insecticides have good possibilities for control of P.xylostella.
