West Indian fruitflies are well-known pests in Puerto Rico. Two species of West Indian fruitnies (Anastrepha momhinpraeoptans Sein and A. suspensa (Loew)) are well known in Puerto Rico. The frequency of their occurrence in the fruits of mango (Mangifera indica L.), particularly in many of the introduced varieties, in guava (Psidium guajava L.), and in jobos (Spondias spp.) may be readily noted throughout the island. In addition A. suspensa attacks orainge and grapefruit (Citrus spp.).

Abstract A description is provided for Meliola mangiferae. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. DISEASE: Meliola mangiferae, as with the family Meliolaceae in general, is found on living leaves parasitizing the epidermis and sometimes deeper tissues, but without production of obvious disease symptoms. HOSTS: Mangifera indica, M. rigida and Mangifera sp. (Hansford, 1961). GEOGRAPHICAL DISTRIBUTION: Brazil, British Guiana, Costa Rica, Cuba, India, Indonesia (Java), Jamaica, Malaysia, Panama, Philippines, Puerto Rico, Surinam, Trinidad & Tobago, Venezuela. Meliola mangiferae is found in practically all areas of mango cultivation, with the exception of Africa and Australia (Hansford, 1961). TRANSMISSION: By air-borne ascospores.

Sri Lanka is a habitat of diverse fruit varieties; nevertheless 95% of them are underutilized by people due to unawareness of their nutritional values and health aspects, and hence become ‘minor fruits’. This study was aimed on revealing vitamin C, iron and antioxidant contents of 29 varieties of minor fruits (MFs) with the comparison of the same with three best commonly consumable fruits (CFs), namely Carica papaya, Mangifera indica and Psidium guajava. Ascorbic acid (Asc), dehydroascorbic acid (DAsc), vitamin C (TC), phenolic (TP), flavonoid (TF), iron (Fe) contents and antioxidant capacities (AOCs) of fruits were determined using standard methods. The results of mean Asc, DAsc, TC, TP, TF and Fe contents in 100 gm of MFs ranged from 3.1 to 121.5 mg, 1.2 to 70.7 mg, 6.6 to 136.1 mg, 24.9 to 1613.3 mg Gallic acid equivalent, 6.2 to 228.0 mg Quercetin equivalents and 0.2 to 4.9 mg respectively. DPPH and Ferric Reducing Antioxidant Power (FRAP) assays were used for AOCs and variation of IC50 values in a DPPH assay was 1.2 to 245.4 mg/ml whereas FRAP values ranged from 9.6 to 486.7 ?mol FeSO4/gm. Among the studied minor fruits, Melastoma malabathricum (Maha bovitiya/ Malabar melastome) is found as the best respect to all considered parameters. As a conclusion, it can be stated that, the Sri Lankan minor fruits are good alternatives to the common fruits as they are recognized as good source of vitamin C, iron and higher content of antioxidants. As an outcome, Sri Lankan minor fruits can be promoted as alternatives to common fruits and as source of revenue for national economy.

Acute Form

The West Indian area is one of the most attractive fields for comparative study. For, as Dr. Mintz has pointed out, it includes territories, generally similar in physical environment, which, nevertheless, differ in their individual histories. The marked divergence in the histories of Puerto Rico and Jamaica during the first half of the nineteenth century is only one instance among many which can be cited as worthy of attention. The interest of this particular case is that it raises the point in an acute form.

Alzheimer’s disease (AD) has been linked with oxidative stress, acetylcholine deficiency in the brain, and inflammatory processes. In the northeast region of Brazil, various plants are used to treat several diseases associated with these processes; then an antioxidant test was performed with those plants in a previous work and twelve species with higher antioxidant activity were selected for AChE inhibition evaluation. The phenolic compounds content was determined by Folin–Ciocalteu test and flavonoid content with AlCl3reagent using UV-visible spectrophotometry. The antioxidant activity was assessed analyzing the inhibitory activity against 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2-azinobis-3-ethylbenzothiazoline-6-sulfonate (ABTS) and by theβ-carotene/linoleic acid system and acetylcholinesterase inhibition using qualitative and quantitative tests. The combination of better acetylcholinesterase inhibitory and antioxidant activities pointed out six species, in descending order, as the best potential sources of therapeutic agents against AD:Hancornia speciosa > Myracrodruon urundeuva > Copaifera langsdorffii > Stryphnodendron coriaceum > Psidium guajava > Mangifera indica. Besides, the phenolic compounds in the species probably contribute to these activities. However, further pharmacological studies to assess the specific applications of these plants against AD are required to confirm these results.

This study records the occurrence of eucoilines (Hymenoptera: Figitidae), parasitoids of the African fig fly Zaprionus indianus Gupta (Diptera: Drosophilidae), in the Brazilian semi-arid Caatinga biome. We obtained from mango (Mangifera indica L.) and guava (Psidium guajava L.) fruits Drosophilidae pupae, which developed into Z. indianus and two species of Eucoilinae parasitoids, Dicerataspis grenadensis Ashmead and Leptopilina boulardi (Barbotin, Carlton & Kelner-Pillaut). This is the first record of the parasitoids D. grenadensis and L. boulardi in the Caatinga biome.
