Le Service français de la Protection des Végétaux est chargé de missions à caractère réglementaire et de missions d'appui technique à la profession agricole telles que: les contrôles sanitaires des végétaux et produits végétaux à l'importation et à l'exportation; la surveillance phytosanitaire du territoire national; l'expérimentation et l'homologation des produits phytosanitaires; l'élaboration et la diffusion des Avertissements Agricoles. Depuis 1983, l'exécution de la plupart de ces missions est considérablement améliorée grâce à l'utilisation de l'informatique. Celle-ci pemet notamment la saisie et le stockage en temps réel de toutes les données présentant un caractère d'urgence (résultats des contrôles en frontière, d'analyses de laboratoires, données météorologiques, biologiques…). Le traitement immédiat de ces données devient possible (analyses statistiques, modélisation, sorties graphiques, tris complexes…), ainsi que leur consultation permanente et décentralisée. Les informations sont diffusées rapidement (messagerie électronique, télécopie). La gestion administrative est accélérée (facturations, abonnements aux Avertissements Agricoles, fichiers d'importateurs, d'exportateurs…). 相似文献

The malvastrum mealybugFerrisia malvastra (McDaniel) (Hemiptera: Coccoidea: Pseudococcidae) is widely distributed in Israel, recorded so far from 30 species of host
plants belonging to 18 families. Its occurrence on herbal plants and on avocado should be considered by farmers in Israel. 相似文献

Derelomus piriformis (Hoffmann), a weevil species developing onPhoenix canariensis, is recorded from Israel for the first time. The species belongs to the group of weevils that are pollinators of palms.D. piriformis is a pollinator ofP. canariensis, but at the same time is injurious to male flowers and occasionally also to female flowers. This group of weevils has not
been previously recorded from Israel and adjacent countries.

The species Ooencyrtus telenomicida (Vassiliev) (Hymenoptera: Encyrtidae) is currently being considered as a candidate for augmentative biological control agent (BCA) against several pests, including Halyomorpha halys (Stål) (Heteroptera: Pentatomidae). Protocols for mass production of a BCA need fundamental information on its biological attributes. Here we tested a possible laboratory host for the rearing of O. telenomicida: the common bug Graphosoma lineatum L. (Heteroptera: Pentatomidae). At tested conditions, O. telenomicida biological parameters were: rm 0.154, offspring production 84.07 specimens/female, sex ratio (% females) 71%, juvenile development time about 16 days, population doubling time 4.52 days, emergence rate about 90%. 相似文献

Six young tortoises Testudo marginata Schoepff, 1792 were experimentally infected with Hemolivia mauritanica (Sergent et Sergent, 1904). The prepatent period ranged from 6 to 8 weeks. Young, smaller, club-like forms (6-9 x 3-6 Am) of gametocytes appeared in the peripheral blood first, whereas mature, elongated, cylindrical forms (9-12 x 5-7 Am) were detected after 1-2 weeks and predominated during later patency. Three of the infected tortoises were euthanized and dissected to study the endogenous stages. Meronts occurred in the cells of the reticulo-endothelial system and in the erythrocytes; these were observed mostly in parenchymatous organs. Mature forms measured 14.2 x 9.3 microm and contained 7-12 merozoites. Cysts with two (exceptionally one) cystozoites were also found predominantly in parenchymatous organs and measured 14.8 x 7.9 microm. Pathological changes attributable to Hemolivia were mild and limited to liver and kidneys. The role of individual developmental stages of haemogregarines is discussed with respect to evolution of heteroxenous life cycle and long-term persistence of parasites in their intermediate hosts. 相似文献

In an effort to improve the generally unfavorable mouse/housefly toxicity ratio of most carbamate insecticides, potential selectophores (nitrile, carbamoyl oxime, carboxylic ester, or amide) were incorporated into a series of phenyl N-methylcarbamates. In addition to the insect and mouse toxicity determinations, the anticholinesterase activity of these compounds was determined for purified housefly head acetylcholinesterase and bovine erythrocyte acetylcholinesterase. The presence of these functional groups, in general, did not give enhanced selectivity ratios and, in one case, (o-N-methylcarbamoyloxyiminomethylphenyl N-methylcarbamate), a very unfavorable selectivity ratio of <0.03 was obtained. A mechanism implicating a Beckmann rearrangement is advanced to rationalize the high rodenticidal activity of this molecule. In general, the carbamates showed poor insecticidal activity when applied alone to the housefly, but, when the flies were pretreated with piperonyl butoxide, the compounds were quite toxic. Finally, an explanation is derived which seeks to justify the inability of these potential selectophores to improve the mouse/housefly toxidity ratio. 相似文献

Intraerythrocytic merogony in Haemogregarina koppiensis (Apicomplexa: Adeleorina: Haemogregarinidae)
During October 2003, a specimen of Amblyrhynchotes honckenii (Bloch, 1795) was captured at low tide, with a hand net, in a rock pool at Koppie Alleen, De Hoop Nature Reserve, South Africa. This fish was heavily parasitized by unidentified gnathiid praniza larvae, caligid copepods identified as Caligus tetrodontis Barnard, 1948, cymothoid isopods identified as Cinusa tetrodontis (Schioedte et Meinert, 1884), and the blood protozoan Haemogregarina koppiensis Smit et Davies, 2001. Giemsa-stained blood smears from this fish revealed new and unusual stages of merogony for H. koppiensis that included small, rounded, likely intraerythrocytic merozoites arranged in circles of eight around the host nucleus. Host cells appeared ghost-like and enlarged compared with normal erythrocytes. Identical merozoites, usually in clusters of up to 16, were also observed free of host cells. The pattern of merogony seen in H. koppiensis is unusual for a fish haemogregarine. 相似文献

Five species of flea beetles (Coleoptera: Chrysomelidae) were recorded for the first time in Turkey:Dibolia numidica Doguet,Longitarsus corynthius corynthius (Reiche et Saulcy),L. onosomae (Peyerimhoff),L. pulmonariae Weise andPhyllotreta ganglbaueri Heikertinger. The zoogeographical distribution of the species was reviewed. Among the species,L. onosmae andD. numidica have a limited distribution area in North Africa, and therefore their presence in Turkey is interesting.

Cuculisyringophilus crotophaginus gen. n. et sp. n. is described from the guira cuckoo Guira guira (Gmelin) from Paraguay and also was collected from the groove-billed ani Crotophaga sulcirostris Swainson from Colombia and Mexico. This new genus is closely related to Neoaulobia Fain, Bochkov et Mironov, 2000 but is distinguished by the following characters: propodosomal setae sce are situated distinctly anterior to level of setae d1, leg setae vs'II are absent, apodemes I are divergent. 相似文献

Herbicide safeners selectively protect crop plants from herbicide damage without reducing activity in target weed species. This paper provides an outline of the discovery and uses of these compounds, before reviewing literature devoted to defining the biochemical and physiological mechanisms involved in safener activity. Emphasis is placed on the effects of safeners on herbicide metabolism and their interactions with enzyme systems, such as cytochrome P450 mono-oxygenases and glutathione-S-transferases. Attention is drawn to the potential wide-ranging applications of safeners and, in particular, their use as powerful research tools with which to identify and manipulate those mechanisms which contribute to herbicide selectivity and resistance. © 1999 Society of Chemical Industry 相似文献
