Genipa americana L. has a diversity of secondary metabolites, including iridoids, phenolic compounds, and alkaloids. Pharmacological and biological properties have also been reported. This study has aimed to evaluate the chemical composition of the essential oil (EO) obtained from the leaves of G. americana and its bioactivity against Aceria guerreronis Keifer (Acari: Eriophyidae), a serious pest of coconut production areas worldwide. EO from the leaves was extracted and analyzed by Gas Chromatography-Mass Spectrometry and flame ionization detection (GC-MS/FID). For the bioassays, the adult coconut mites were subjected to increasing concentrations of EO. The analyses showed a predominance of sesquiterpenes, followed by monoterpenes, aldehydes, and fatty acids. The EO (LC50 = 0.41 mg mL-1; LC90 = 6.43 mg mL-1) showed toxicity and repellent effects against the coconut mite. The tested EO has the potential to develop as a natural product, with acaricidal activities against A. guerreronis, in order to assist in the control of the coconut mite.

One of factors that cause a bad quality of Boer Goat frozen semen is the growth of bacterial. This can be overcome by adding antibiotics such as streptomycin. To further suppress the growth of bacteria can be added other ingredients that contain antibacterials such as sweet orange essential oil. The purpose of this research is to know the percentage value of Membrane Integrity and Acrosome Integrity on Boer Goat frozen semen with addition sweet orange essential oil and streptomycin. The method used was experimental using Completely Randomized Design with 5 treatments and 5 replications. The treatment in this research is addition 0%, 0,25%; 0.5%; 0.75% and 1% sweet orange essential oil on tris yolk and streptomycin extender. The results showed the best treatment addition combination streptomycin and sweet orange essential oil to percentage Membrane Integrity and Acrosome Integrity is increase 1% sweet orange essential oil.Keywords: Boer Goat, essential oil, frozen semen, streptomycin, sweet orange.

AbstractThe purpose of this study was to know the quality of Boer liquid semen during storage by adding sweet orange essential oil and gentamicin into the tris yolkextender.The semenlongevity test was carried out by storing semen in a closed tube at room temperature and refrigerator, and evaluated motility and Viability every 3 hours at room temperature and 12 hours in refrigerator. The results showed that the characteristics of the liquid semen, with the addition of 1% of essential oils showed percentage of motility and Viability significantly higher than 0.5% and without the addition of essential oil, either stored at room temperature or in the refrigerator. This may be related to the content of essential oils of sweet orange peel containing flavonoids and antibacterials that are capable of maintaining liquid semen quality of Boer Goat.In addition, gentamicin contains antibacterials capable of suppressing the growth of bacteria which can damage and durabilitythe spermatozoa.Keywords: Boer Goat,Gentamicin, Liquid semen, Sweet orange

Considerable Damage

The coconut mite, Aceria guerreronis Keifer, has emerged as a common menace to most of the coconut plantations in India. After its first upsurge in Kerala at the end of the 1990´s, the mite has spread to many states in southern and northern India, causing considerable damage. Coconut provides one third of the agricultural income in the regions in which it is grown and more than 10 million people are dependent on this cash crop directly or indirectly through coconut-based industries like coir, copra, oil, honey, furniture, handicrafts, beverages, bakery products and so on. The economic instability of the coconut farming community and the people employed in coconut-based industries rank the highest order. A critical assessment of the various problems created by A. guerreronis in the agricultural economy of India is presented in order to supplement data on crop loss through nut malformation, nut fall, loss in fibre and copra. Varietal differences in susceptibility of the plant and future strategies in terms of management practices for an early control of the mite are discussed, and suggestions for future activities to alleviate mite damage are presented.

Bedbugs are harmful human blood-sucking ectoparasites. The disadvantages of a bedbug bite cause itching, redness bumps, secondary infections, and anemia in children. Bedbugs controller so far uses harmful chemical pesticides, but reappearance of bedbugs indicates less effective chemical pesticides, and becomes a serious problem. So it needs safer controller for human health. This study aims to analyze the d-Limonene activity of orange peel (Citrus sinensis L.) in controlling the bedbug infestation (Cimex cimicidae). The study was conducted through 5 stages: d-Limonene isolation, GC-MS characterization, bioassay Y test d-Limonene nanoparticles, SEM characterization, and d-Limonene activity test on bedbug. The results showed that the essential oil of orange peel contained the main compounds as d-Limonene (90.018%), 1,6-Octadien-3-ol, 3,7-dimethyl- (3,017%), β-Myrcene (2.071%), Octanal (0.349%), 1-Octanol (0.589%), 1R-α-Pinene (0.688%), 6-Octen-1-ol, 3,7-dimethyl- (0.667%), 3-Cyclohexene-1- methanol, α, α, 4-trimethyl-, (S) - (1.453%), and Bicyclo [3.1.1] heptane, 6.6-dimethyl-2-methylene-, (1S) - (1.147%). The Bioassay Y test shows that d-Limonene was both repellent and fumigant, d-Limonene nanoparticles had uneven and irregular surface morphology, and in the flea activity test showed more than 50% bedbugs death. These research concluded that d-Limonene compounds from sweet orange peel had activity to control the bedbugs.
