“…A complex of pests causes damage on hazelnuts in North America, Europe and Turkey (Aliniazee, 1999). Even though Turkey places on the top of the list among all the countries producing hazelnut in hazelnut production and exportation, it is way back of many of them in terms of product harvested per unit field.…”

Abstract:The alder leaf beetle (Agelastica alni L., Coleoptera: Chrysomelidae) causes approximately 10% of total economic damage to hazelnut product per year in Turkey. A. alni larvae are susceptible to several pathogens indigenous to the area in which these insects occur in Turkey. In the present study, in order to find a more effective and safer biological control agent against this common pest, we evaluated the various biological agents' insecticidal activity during the four hazelnut seasons from 2002 to 2005 on the larvae of the alder leaf beetle collected from the vicinity of Trabzon, Turkey. The tested agents are 25 insect-originating bacteria, 2 bacterial toxins and 1 viral preparation. The results showed that the highest insecticidal activity was obtained by bacterial isolates at 1.8 × 10 9 bacteria/mL dose, within ten days on the larvae of A. alni. These are 90% for Bacillus thuringiensis biovar tenebrionis (4AA1), Bacillus sphaericus (Ar4, isolated from Anoplus roboris L., Col.: Curculionidae), and Bacillus thuringiensis (Mm2, isolated from Melolontha melolontha L., Col.: Scarabaeidae). Our results indicate that these isolates may be valuable as biological control agent.

“…1, Table 1). The average length of the forewing was determined to be 10 ± 0.8 mm for the female, and 9.3±0.3 for the male insects (Table 1), AliNiazee (1998) found that the adults were greyish red in colour, rostrum was slander, strongly curved and longer than body in the female, shorter than body in the male. The existence of adults starts in mid-March and the maximum density is reached in mid-May, depending temperature.…”

“…However, when the temperature rises the 16EC, they start flying long distances. Adults of has beetle moved towards different plants for feeding later adults which were laying migrated on the fruits that were not yet mature According to literature knowledge, the adults feed on hazelnut and on the fruits of various trees such as pear, peach, more rarely apple, plum and cherry (Ural et al, 1973;Paparatti, 1990;AliNiazee, 1998). Starting from early June, the eggs which were collected, measured, and photographed, They were conical and transparent, and 0.795 ± 0.14 x 0.525 ± 0.11 mm in size and, average (Fig.…”

The hazelnut beetle (Coleoptera: Curculionidae, Balaninus nucum L.) found in many regions of the world. In order to logical control of this pest, it is necessary to determine the biology and form of its damage. In this study, the biology damage caused by B. nucum were investigated on larvae and adults collected from the coast of Trabzon province in period of 1996-1998. In the end of the present investigation, the wing (10±0.8 mm for females, 9.3 ± 0.3 mm for males) and rostrum length 0.3 ± 0.4 mm for females. 3.8 ± 0.2 mm for males) of the adults, sex ratio (1/1), the dimensions of eggs (0.795 ± 0.14, 0.525 ± 0.11 mm), and instars of larvae (512.5 ± 15; 800 ± 8; 1005 ± 10; and 1295 ± 6 μm in diameter) were detarmined. Also, the appearance of the damage caused by the insect was observed.

“…At the beginning of August the larvae emerge from the nuts and burrow into the ground, where this insect spends a wintering diapause (Akça & Tuncer, 2005). The weevil life cycle can last for 2 years, including overwintering larval and adult stages (Coutin, 1992;AliNiazee, 1998;Bel-Venner et al, 2009).…”

The hazelnut weevil, Curculio nucum L. (Coleoptera: Curculionidae) is a pest affecting hazelnut orchards in Europe, with an important economical repercussion. Its potential control, short-term f ield persistence and the vertical distribution of native entomopathogenic nematode strains were tested in Muntanyes de Prades, Tarragona (NE Iberian Peninsula) over two consecutive years. Steinernema feltiae strain D114, Steinernema sp. strain D122 and Heterorhabditis bacteriophora strain DG46 were used in summer and spring applications at a dosage of 5 · 10 5 IJs m -2 . The three nematode species reduced the hazelnut weevil population, ranging from 32% to 88% efficacy, without significant differences in efficacy or between the two applications. Persistence evaluation was carried out during 9 weeks for S. feltiae (D114), Steinernema sp. (D122) and H. bacteriophora (DG46) and showed all species capable of lasting for this period. Nematodes and larval vertical distribution was assessed. Most of the hazelnut weevil stayed within the first 25 cm although some were found as deep as 40 cm. Entomopathogenic nematodes were found along all 40 cm depth. This study proves the suitability of entomopathogenic nematodes to control the hazelnut weevil.Additional key words: hazelnut orchard; biological control; Steinernema; Heterorhabditis; vertical distribution; spring application. * Corresponding author: Fernando.Garcia@uab.cat Received: 18-03-13.
