- Description:
- Duponchelia fovealis Zeller is a polyphagous insect that has been recently reported attacking strawberry plants (Fragaria x ananassa Duchesne). Despite its economic importance there are few studies on this pest because it is difficult to rear it in the laboratory. With a constant supply of insects, studies on alternative methods of pest control can be conducted. This study aimed at developing an artificial diet for rearing D. fovealis with biological characteristics similar to those reared on their natural diet. This study was carried out in a climate-controlled room (25°C ± 2°C, RH 70% ± 10%, and 14L : 10D). The natural diet consisted of 'San Andreas' strawberry leaves (D1), while the artificial diet (D2) was developed in which beans, casein, soy protein, yeast and wheat germ are used as sources of protein. Five instars were identified. D. fovealis completed its life cycle in 38 and 40 days when fed D1 and D2, respectively. Survival was highest for the larvae fed the artificial diet. Females fed D1 lay a mean of 300.2 ± 62.3 eggs, while those fed D2, 220.3 ± 41.8 eggs. The artificial diet is suitable for the continuous rearing of D. fovealis in the laboratory., Maria A. C.

- Description:
- Severoameričtí raci (např. rak pruhovaný a rak signální vyskytující se i v ČR) jsou příkladem invazních živočichů, jejichž invazní potenciál je zesílen přenosem onemocnění nebezpečného pro příbuzné druhy z jiných geografických oblastí. Původcem nemoci, tzv. račího moru, je Aphanomyces astaci ze skupiny Oomycetes způsobující úhyny celých populací evropských raků. Račí mor se v Evropě vyskytuje už od 19. století a i v současnosti zůstává přes intenzívní výzkum jedním z nejvýznamnějších faktorů ohrožujících původní raky (u nás jde o raka říčního a raka kamenáče, u nichž bylo jen od roku 2004 zaznamenáno deset případů zdecimování populací touto nemocí)., North American crayfish species such as the Spiny-cheek Crayfish and the Signal Crayfish are examples of invasive animals with an ability to carry and transmit a disease lethal to their relatives from other parts of the world. The disease called the crayfish plague and caused by Aphanomyces astaci (Oomycetes) may eradicate whole populations of the indigenous European crayfish. The disease is known in Europe from the 19th century and despite intensive research it is still one of the main factors endangering indigenous crayfish., and Eva Kozubíková-Balcarová.

- Description:
- The conifer needle scale, Nuculaspis abietis (Schrank) emerged as an important pest of conifers in the Kelardasht region of Mazandaran province, Iran, in the late 1990's. This pest feeds on conifer needles and twigs causing needle drop and branch desiccation. Its discovery in Kelardasht in Mazandaran Province necessitated a local quarantine of conifers in the genera Picea, Abies, and Pinus. We studied the life history and ecology of this scale on Norway spruce, Picea abies, under laboratory and natural field conditions. The complete life cycle of females required 206.4 ± 5.7 days in the laboratory (25 ± 1°C, 65-75% RH, 14L : 10D) and 315.7 ± 9.3 days under field conditions. In Kelardasht, numbers of adult males and females peaked in mid-June and early May, respectively, and numbers of first and second instar nymphs in mid-July and early September. Lifetime fecundity was estimated to be 57.3 ± 5.1 eggs and 54.0 ± 4.4 nymphs per female under laboratory conditions. The sex ratio ranged from 59% female for second instar nymphs to 71% female for adults. Aspidiotiphagus citrinus (Crawford) (Hymenoptera: Aphelinidae) was found naturally parasitizing the scale and overwintering in the larval stage on second instar nymphs. First generation adult wasps emerged in spring from overwintered second instar nymphs to parasitize 64.75% of first instar scales. Second generation wasps emerged from early September to mid-October and parasitized 19.75% of second instar scales, for a cumulative parasitism rate of 84.5%. and Arash RASEKH, J.P.

- Description:
- Ačkoli bylo světélkování u hub doloženo již ve starověku, intenzivnějšího vědeckého studia se tomuto jevu dostává teprve v posledních letech. Článek shrnuje naše dosavadní poznání bioluminiscence u hub z hlediska evolučního, ekologického i fyziologického. Jeho součástí jsou i fotografie dvou tropických druhů se světélkujícími plodnicemi - Mycena chlorophos a Filoboletus manipularis., Bioluminescence in fungi was first observed in the Archaic period or earlier, but it has only recently been studied scientifically. This paper sums up our knowledge on this phenomenon from evolutionary, ecological, and physiological points of view. Included are photos of two tropical species with luminescent fruiting bodies - Mycena chlorophos and Filoboletus manipularis., and Michal Sochor, Zuzana Egertová.
