ABSTRACT The use of toxic baits with spinosyns (spinosad and spinetoram), along with the parasitoid Diachasmimorpha longicaudata, is a sustainable alternative for the management of Ceratitis capitata. This study aimed to evaluate the lethal concentration (LC) and lethal time (LT) of spinosad and spinetoram, associated with the food lures sugarcane molasses at 7 %, Biofruit at 3 %, Ceratrap® at 1.5 %, Flyral® at 1.25 %, Isca Samaritá® and Samaritá Tradicional® at 3 %, on C. capitata, under laboratory conditions, as well as their effect, at the concentration of 96 mg L-1, on D. longicaudata. For the lethal time data, mortality was assessed at 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 36, 48, 60, 72, 84 and 96 h after the exposure to the toxic baits. The lowest lethal concentrations (LC50 and LC95), to spinetoram (0.5 mg L-1 and 3.7 mg L-1, respectively) and spinosad (0.8 mg L-1 and 7.8 mg L-1, respectively), corresponded to the association with Samaritá Tradicional® at 3 %. The lowest lethal time (TL50), in hours, for the spinosad insecticide, corresponded to the formulation containing Biofruit at 3 % (6.6), and, to spinetoram, Samaritá Tradicional® at 3 % (7.9). For D. longicaudata, the formulations that caused the lowest mortality corresponded to the association of Biofruit® at 3 % with spinosad (4.7 %) and Samaritá Tradicional® at 3 % with espinetoram (3.5 %). The toxic baits formulated with spinosad and espinetoram, associated with Isca Samaritá® at 3 %, caused a mortality rate of more than 60 % to the parasitoid D. longicaudata.

Abstract: The objective of this work was to assess the lethal concentration and lethal time (LC and LT) of spinosad and spinetoram, combined with different food lures, and their residual effects on South American fruit fly (Anastrepha fraterculus). The toxic baits were offered in eight concentrations (2, 6, 14, 35, 84, 204, 495, and 1,200 mg L-1), combined with the following food lures: 7% sugarcane molasses, 3% Biofruit, 1.5% CeraTrap, 1.25% Flyral, 3% Samaritá Bait, and 3% Samaritá Tradicional; diluted food lures in water were used as controls. The residual effect of the formulations at 96 mg L-1 concentration were evaluated for 21 days and were compared with that of the commercial bait Success 0.02 CB. Both insecticides were toxic to adults of A. fraterculus, and mortality varied with the food lure used. The LC50and LT50ranged from 15.19 to 318.86 mg L-1and from 11.43 to 85.93 hours, respectively. Spinosad was 2 to 36 times as toxic as spinetoram when combined with different hydrolyzed proteins. Toxic baits formulated with spinosad and spinetoram (96 mg L-1) caused mortality equivalent to the one by Success 0.02 CB (90.2%), when assessed on the day of application. Toxic baits formulated with 3% Biofruit + spinosad and 3% Samaritá Bait + spinetoram are effective for managingA. fraterculusand provide up to seven days of residual effect in the absence of rain; however, only Success 0.02 CB caused more than 80% mortality for up to 21 days.

Abstract Ceratitis capitata (Wiedemann, 1824) is the main insect pest of fruits worldwide. The objective of this study was to evaluate the toxicity and residual effects of the ready-to-use toxic baits Success 0.02CB (0.24 g of active ingredient [a.i.] per liter of spinosad) and Gelsura (6 g of a.i./liter of alpha-cypermethrin) and to compare them with other food lures containing spinosad and malathion mixed with hydrolyzed protein (Biofruit 5% and Flyral 1.25%), Anamed without dilution or sugarcane molasses (7%) against adult C. capitata in laboratory and greenhouse trials. Ceratitis capitata adults were highly susceptible to all toxic bait formulations (mortality > 80%) until 96 h after exposure. The lowest LT50 (hours) of toxic baits were 2.32 (Gelsura at 4,000 mg/liter), 4.26 (Gelsura at 2,000 mg/liter), 4.28 (Anamed + malathion) and 4.89 (sugarcane molasses + malathion), while formulations containing spinosad (Biofruit, Flyral, Anamed and Success 0.02CB) showed LT50 of approximately 11 h. Without rain, Gelsura (2,000 mg/liter) and all spinosad formulations provided mortality superior to 80% 14 d after application. Gelsura and Anamed + spinosad showed higher resistance to a 5-mm simulated rain, similar to Anamed + malathion, while the other formulations had its efficacy decreased. All toxic baits were effective on adult C. capitata in residual experiments without rain while Anamed + spinosad caused high adult mortality after 5 to 25 mm rains. Gelsura and Anamed + spinosad can be used to replace toxic baits containing malathion for C. capitata population management.

Program pembangunan kesehatan di Indonesia masih berfokus pada upaya peningkatan derajat kesehatan ibu dan anak terutama pada masa prenatal. Hal ini disebabkan masih tingginya Angka Kematian Ibu (AKI) dan Angka Kematian Bayi (AKB). ASI yang diberikan sejak usia dini dan dilanjutkan dengan ASI eksklusif selama 6 bulan dapat menurunkan angka kesakitan dan angka kematian bayi serta meningkatkan tumbuh kembang bayi secara optimal.  Penelitian ini bertujuan untuk mengetahui efektifitas pemberian konseling laktasi terhadap pelaksanaan menyusui pada ibu hamil trimester III. Desain penelitian menggunakan quasi eksperimen dengan rancangan One Group Pre-test dan  Post-test Desain. Populasi dalam penelitian ini adalah ibu hamil trimester III dan sampel yang diambil adalah 18 ibu hamil. Alat penggumpulan data menggunakan lembar observasi BREAST (body position, respons, emotional bonding, anatomy dan sucking time). Analisis data menggunakan wilcoxon.Hasil penelitian didapatkan pelaksanaan menyusui sebelum dilakukan konseling laktasi dalam kategori kurang (72,2%) sedangkan pelaksanaan menyusui setelah dilakukan konseling laktasi (77,8%) dalam kategori baik. Konseling laktasi efektif dilakukan untuk meningkatkan pelaksanaan menyusui denganp-value 0,003 (p<0,005).Konseling laktasi seharusnya diberikan pada masa prenatal sehingga pada saat postpartum, ibu sudah mampu memberikan asi secara maksimal. Pendampingan terhadap ibu hamil juga berperan dalam pelaksanaan pemberian ASI.   Kata kunci : Konseling laktasi, ASI, pelaksanaan menyusui   THE EFFECTIVENESS OF LACTATION COUNSELING IN THE 3rd TRIMESTER PREGNANT WOMEN ON BREASTFEEDING IMPLEMENTATION   ABSTRACT Indonesia's health development program still focuses on improving mother and child health, especially at the prenatal stage. It is due to the high maternal mortality rate (MMR) and Infant Mortality Rate (IMR). Breastmilk given from an early age and continued with exclusive breastfeeding for six months can reduce infants morbidity and mortality rate and increase their optimal growth. The purpose is to investigate the effectiveness of lactation counseling to the implementation of breastfeeding in third-trimester. The study design used quasi experiments with one group pre-test and post-test. Population was the 3rd-trimester pregnant mothers, and the samples were 18 mothers. The data collection tool used BREAST observation sheets (body position, response, emotional bonding, anatomy and sucking time). Data analysis used Wilcoxon. The result of the research shows that breastfeeding before lactation counseling is in less category (72,2%) while breastfeeding after lactation counseling (77,8%) is in a goodcategory. Effective lactation counseling is performed to improve the implementation of breastfeeding with p-value 0.003 (p <0.005). Lactation counseling should be given during the prenatal period so that at the time of postpartum, the mother has been able to give breastmilk maximally. Mentoring for pregnant women also plays a role in the implementation of breastfeeding Keywords: lactation counseling, breast milk, breastfeeding implementation

Virulence of entomopathogenic fungi <em>Metarhizium anisopliae</em> and <em>Beauveria bassiana</em> were tested against Arabian Rhinoceros Beetle, <em>Oryctes agamemnon arabicus</em> larvae. Four concentrations (1×10<sup>5</sup>, 1×10<sup>7</sup>, 1×10<sup>9</sup> and 1×10<sup>11</sup> conidia/mL<sup>–1</sup>) of two locally isolated entomopathogenic fungi spore suspensions were used in this study via larval direct spraying. Results revealed that both isolates can cause high mortality rate reaching 100% after 29 days. However, <em>Beauveria bassiana</em> scored higher mortality rate in short time especially at the concentration of 1×10<sup>11</sup> conidia/ mL<sup>–1</sup> with lethal time (LT)<sub>50</sub> 12.75 and LT<sub>90</sub> 20.00; while, <em>Metarhizium anisopliae</em> caused the higher percentage of malformed adults. Moreover, both isolates affected insect’s life cycle particularly in the pupal stage which was reduced remarkably by almost 50% in comparison with the control treatment.

DBD masih merupakan masalah kesehatan masyarakat utama di Indonesia. Upaya pencegahan yang dilakukan saat ini menggunakan insektisida berbahan dasar kimia yang dapat merusak lingkungan juga menimbulkan resistensi. Penggunaan larvasida alami dari tumbuhan dapat menjadi alternatif insektisida, salah satunya adalah jahe merah (Zingiber officinale var. rubrum) yang dapat dijadikan sebagai insektisida alami karena adanya kandungan senyawa aktif. Tujuan penelitian ini adalah untuk mengetahui tingkat kematian, perbedaan rerata kematian larva Aedes albopictus serta mengetahui Lethal Time dan Lethal Concentration. Jenis penelitian ini merupakan penelitian true eksperimental dengan posttest only control group design. Hasil penelitian menunjukkan bahwa kematian larva 100% lebih cepat pada konsenrasi 8% yaitu setelah 6 jam pengujian. Hasil Uji Kruskal Wallis untuk melihat perbedaan rerata kematian larva setiap jam kelompok perlakuan ekstrak jahe merah dengan kelompok kontrol menunjukkan terdapat perbedaan secara signifikan rerata kematian larva (0,000 < 0,05). Hasil uji probit Lethal Time menunjukkan bahwa diperlukan waktu 2,196 jam dalam mematikan 50% larva dan 4,788 jam dalam mematikan 99% larva dengan konsentrasi 8% sedangkan Lethal Concentration menunjukkan bahwa diperlukan konsentrasi sebesar sebesar 0,772% dalam mematikan 50% larva dan 1,973% dalam mematikan 99% larva setelah 9 jam pengukuran. Perlu dilakukan penelitian lebih lanjut untuk mengembangkan ekstrak jahe merah yang aman dan layak pakai namun tidak menghilangkan senyawa yang ada pada ekstrak jahe merah.

Aedes aegypti merupakan vektor penyakit Demam Berdarah Dengue (DBD) yang masih menjadi masalah kesehatan di Indonesia. Upaya pengendalian dan pemberantasan Ae. aegypti saat ini banyak dilakukan, salah satunya dengan menggunakan insektisida kimiawi. Penggunaan insektisida kimiawi secara berkelanjutan menimbulkan resistensi pada nyamuk vektor. Telah diketahui bahwa daun tanaman cengkeh (Syzygium aromaticum L) mengandung flavonoid dan saponin yang berpotensi sebagai insektisida. Untuk membuktikan hal tersebut dilakukan penelitian yang bertujuan untuk mengetahui efektifitas dari ekstrak daun cengkeh dengan menuntukan nilai Lethal Concentration (LC50 dan LC90) dan Lethal Time (LT50dan LT90). Penelitian eksperimen yang menggunakan rancangan acak kelompok ini dilakukan dengan lima konsentrasi, yaitu; 10%; 20%; 30%; 40%; dan 50% ekstrak daun cengkeh, dan dengan dua kontrol yaitu, kontrol negatif yang berisi aquades, kontrol positif yang berisi tranflutrin12,38g/l, dengan empat kali pengulangan setiap konsentrasi dan kontrol. Pengamatan terhadap jumlah nyamuk yang mati setiap 5, 10, 20, 40, 60, 120, 240, 480, dan 1440 menit setelah perlakuan. Dari hasil Uji ANOVA yang diuji lanjut dengan Uji BNT diketahui bahwa konsentrasi yang paling efektif dibandingkan kontrol negatif dan sama dengan kontrol positif adalah 50%. Dari analisis probit diperoleh nilai LC50 sebesar 43,709%, sedangkan untuk nilai LC90 sebesar 49,069%. Nilai LT50 dan LT90 dari penelitian ini adalah 1220,152 menit dan 1126,488 menit. Kesimpulan dari penelitian ini adalah ekstrak daun cengkeh berpotensi sebagai insektisida terhadap Ae. aegypti, dan konsentrasi ekstrak yang paling efektif adalah konsentrasi sebesar 50%.

Abstract The Mediterranean fruit fly, Ceratitis capitata Wiedemann, is a deleterious pest worldwide affecting fruit production. The entomopathogenic nematodes (EPNs) are a potential biocontrol agent that could be effectively used to control this Mediterranean fruit fly. In this study, five EPN strains reported from different fields in Morocco were evaluated for their efficacy against C. capitata. In laboratory assays, Steinernema feltiae-SF-MOR9, S. feltiae-SF-MOR10 and Heterorhabditis bacteriophora-HB-MOR7 strains showed significantly higher infectivity and penetration rates when compared to the other strains. S. feltiae-SF-MOR9 caused the highest larval mortality rate (80%) at 50 infective juveniles (IJs) cm−2. However, additional results showed that both S. feltiae strains were significantly effective in controlling C. capitata larvae in apricot (Prunus armeniaca) fruits on soil surface with high mortality rate at 50 and 100 IJs cm−2. Different soil textures and moisture levels resulted in a significant variation in EPN strain virulence against C. capitata. Sandy clay loam soil in combination with 50 IJs cm−2 of S. feltiae (SF-MOR9 or SF-MOR10) caused a higher mortality rate of C. capitata larvae. Furthermore, applying these EPN strains at 50–100 IJs cm−2 in combination with 10–15% moisture level showed optimal results against C. capitata larvae. Therefore, those two Moroccan EPN strains could be used as promising eco-friendly biological agents against C. capitata.
