A community of frugivorous insects was studied by rearing of 25565 individual insects representing three orders (Coleoptera, Lepidoptera and Diptera except Drosophilidae) from 326 woody plant species in a lowland rainforest in Papua New Guinea. Fruits from 19.3% of plant species were not attacked by any insect order, 33.4% of plant species were attacked by a single order, 30% by two orders and ...

Fungi Trichoderma spp. are present in nearly all soils and other habitats. Most of Trichoderma strains are efficient for control of some pathogens. Some strains induce plant native defence mechanisms. Botrytis cinerea [Pers.: Fr.] causes economic losses on a wide range of cultivated plants and stored fruits. In presented work Trichoderma asperellum [strain T1] isolated from commercial product w...

Cleistogamy (CL) in angiosperms historically has been understudied; however, its co-occurrence with chasmogamy (CH) across many plant species suggests a fitness advantage to maintaining this mixed-mating strategy. Maintenance of mixed-mating has been attributed to reproductive assurance, resource allocation or genetic trade-offs. Our goals were to explore patterns of CH and CL, quantify reprodu...

Background: Melia indica and M. azedarach (Meliaceae) are widely used in traditional medicine. These species are considered as natural pesticides. Their major compound is azadirachtin (AZD) which is considered as the marker for quality control of these species. Objective: In the present investigation, AZD content of the leaves and fruits (comprising the whole fruit, peel, pulp and seeds) of M....

An experiment was conducted to manage the eggplant (brinjal) shoot and fruit borer Leucinodes orbonalis Guenée (Lepidoptera: Crambidae), the leafhopper Amrasca biguttula biguttula (Ishida) (Hemiptera: Cicadellidae), and the whitefly Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) during kharif, the southwest monsoon season (Jul-Oct), in 2010 and 2011 at an experimental farm at the Division ...

study on relationships between yield and its components will improve the efficiencyof a breeding program with appropriate selection criteria. in this study,interrelationships between yield and its components in cantaloupe were investigatedusing sequential path coefficient analysis. to determine important components of yieldin cantaloupe, 49 genotypes generated from 7 × 7 diallel, were evaluated...

introduction after crops harvesting, conditions and durations of storage are considered as the most crucial factors formaintaining the nutritional value and quality of agro-horticultural products such as tomato (lycopersicom esculentum mill.) and its waste reduction. however, the rhizopus rot (rhizopus stolonifer) and black spot rot (alternaria alternate) are the most important postharvest dise...
