The use of semiochemicals, both sex pheromones and food attractants, in monitoring the olive fly, Bactrocera oleae, has become well established in most olive-growing countries of the Mediterranean basin. There is an ever-increasing degree of sophistication that is being introduced in the way trap catch data are collected and interpreted, making for a substantially more rational use of conventio...

An automatic recognition algorithm was developed and tested for detection of certain defects or contaminants in X-ray images of agricultural commodities. Testing of the algorithm on wheat kernels infested with larvae of the granary weevil, Sitophilus granarius (L.) yielded comparable results to those obtained by human subjects evaluating digitized X-ray film images (14.4% overall error vs. 15.6...

Characterization and selection of olive clones for the production of olive oil is essential in Turkey because of its profitable exploitation. AP-PCR (Arbitrarily-Primed PCR) is a technique that can distinguish the genetic relationship among plant species and other organisms. In this study, AP-PCR approach was used in order to determine the genetic relationship of different six olive clones. The...

This work records the presence of 13 species tubuliferan thrips from Maltese Islands. Eleven these species, namely Bolothrips dentipes , B. insularis Priesneriella mavromoustakisi Gynaikothrips uzeli Haplothrips acanthoscelis H. aculeatus setiger tritici Karnyothrips flavipes Liothrips reuteri and Neoheegeria dalmatica are new for Two species: ficorum can be described as subcosmopolitan in dist...

Herbivory with crypsis is not well documented in ferns. The present record of cryptic coloration of coccid Saissetia filicum Boisduval (Homoptera: Coccidae) to the sori of a fern species Asplenium nidus L. (Aspleniaceae) is unique. Predatory beetles (Jauravia sp., Coleoptera: Coccinellidae) that feed on the coccids, are suggested to be selective pressure for the development of the present homop...
