Biological control ofCuscuta spp. II. Biology and host-plant range ofMelanagromyza cuscutae Hering [Dipt. agromyzidae]
BioControl - Tập 12 - Trang 481-489 - 1967
G. M. Baloch, A. I. Mohyuddin, M. A. Ghani
Melanagromyza cuscutae Hering était considéré comme un agent biotique prometteur pour la lutte biologique contre la Cuscute. Dans les conditions de laboratoire, les imagos en présence de Cuscute et d'une solution de miel s'accouplent 1 à 4 jours après leur émergence, habituellement le matin, pendant 2 à 5 heures. Les femelles pondent 2 à 8 jours plus tard et cela durant 6 à 15 jours; au cours de ...... hiện toàn bộ
Effects of 37 fungicides on the rove beetleAleochara bilineata (Col.: Staphylinidae) in the laboratory
BioControl - Tập 40 - Trang 145-152 - 1995
L. Samsøe-Petersen
Effects of 37 fungicides — several of which were mixtures — on adult females of the rove beetle,Aleochara bilineata, were investigated in the laboratory. The pesticides were tested in concentrations equivalent to the highest recommended dosages for practical use. Mortality, egg production and hatch of the eggs were recorded. Most fungicides had no serious effect on any of the parameters measured. ...... hiện toàn bộ
First Quantitative Study of Rove Beetles in Oklahoma Winter Wheat Fields
BioControl - Tập 51 - Trang 79-87 - 2006
N. C. Elliott, F. L. Tao, K. L. Giles, T. A. Royer, M. H. Greenstone, K. A. Shufran
Adult rove beetles (Staphylinidae) were sampled every 7–14 days from one winter wheat field located in each of the four major wheat growing regions of Oklahoma during the 1999–2000 and 2000–2001 growing seasons. The number of cereal aphids per tiller, wheat plant growth stage, and wheat tiller density also were estimated. A total of 12 genera representing 13 species of beetles were collected from ...... hiện toàn bộ
Sensory receptors of the ovipositor ofTrichogramma maidis [Hym.:Trichogrammatidae]
BioControl - Tập 35 - Trang 293-299 - 1990
A. Le Ralec, E. Wajnberg
Sensory receptors of the ovipositor ofTrichogramma maidis are described. Sense organs are found on the 2nd valvifers (1 type), on the tip of the 3rd valvulae (2 types) and on the 1st valvulae (4 types). The nature and possible functions of these sensilla are discussed.
Remarques sur la «Maladie transparente» des larves deMelolontha melolontha L. (Col. scarabaeidae)
BioControl - Tập 6 - Trang 191-196 - 1961
B. Hurpin, C. Vago
Die Krankheitssymptome der «Wassersucht» vonMelolontha-Larven können mit der Rickettsiose zusammenhängen, wenn diese Infektion unter gewissen Bedingungen (ungünstige Temperatur, Antibiotika-Wirkung, Antisera, etc.) abläuft. Die Zytopathologie der Krankheit wird beschrieben.
Toxicity and kinetics of spinosad in different developmental stages of the endoparasitoid Hyposoter didymator (Hymenoptera: Ichneumonidae) and its host Spodoptera littoralis larvae (Lepidoptera: Noctuidae)
BioControl - Tập 53 - Trang 569-578 - 2007
Pilar Medina, José Morales, Guy Smagghe, Elisa Viñuela
The toxicity of spinosad was evaluated using the RaPID Assay® Spinosad immunosorbent assay in different developmental stages of the parasitoid, Hyposoter didymator, and in its host, fourth-instar larvae of the cotton leafworm Spodoptera littoralis. Spinosad was applied directly to pupae and adults of H. didymator (ingestion or topical application) or to the immature stages of the parasitoid via th...... hiện toàn bộ
Reaping benefits from an invasive species: role of Harmonia axyridis in natural biological control of Aphis glycines in North America
BioControl - Tập 62 - Trang 331-340 - 2016
Robert L. Koch, Alejandro C. Costamagna
Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae) is an invasive species present in numerous agroecosystems in North America. Despite adverse impacts as a threat to native biodiversity, a nuisance household invader and a pest in fruit production, H. axyridis also plays a beneficial role as a major component of assemblages of generalist predators in several agricultura...... hiện toàn bộ
Response of Pseudomonas tolaasii, the causal agent of mushroom brown blotch disease to the volatile compounds produced by endofungal bacteria
BioControl - Tập 66 - Trang 421-432 - 2021
Samira Ghasemi, Behrouz Harighi, Mahdi Mojarrab, Abdolbaset Azizi
Volatile organic compounds (VOCs) produced by bacteria have significant potential to control phytopathogens. In this study, the VOCs produced by endofungal bacteria Pseudomonas sp. Bi1, Bacillus sp. De3, Pantoea sp. Ma3 and Pseudomonas sp. De1 isolated from wild growing mushrooms were evaluated in vitro for their antagonistic activity against Pseudomonas tolaasii Pt18, the causal agent of mushroom...... hiện toàn bộ
Mortality by parasitization in the association between the egg-pupal parasitoid Fopius arisanus and Ceratitis capitata
BioControl - Tập 48 - Trang 275-291 - 2003
Riccardo Moretti, Maurizio Calvitti
We studied the interaction betweenthe egg-pupal parasitoid Fopius (+ Biosteres) arisanus (Sonan) (+Opius oophilus Fullaway) (Hymenoptera: Braconidae) and Ceratitis capitata (Wiedemann)(Diptera: Tephritidae) to assess the totalimpact of the parasitoid on the survival ofthis host. We tried to discover the factorsdetermining host suitability, measure actualpercent parasitism, and quantify host mortal...... hiện toàn bộ
Characterization of a Pseudomonas fluorescens strain from tomato rhizosphere and its use for integrated management of tomato damping-off
BioControl - Tập 52 - Trang 683-702 - 2007
Jayaraman Jayaraj, T. Parthasarathi, N. V. Radhakrishnan
A highly antagonistic Pseudomonas fluorescens strain was isolated from tomato rhizosphere and characterized for its in vitro and in vivo biocontrol potential against Pythium aphanidermatum. The identified Pseudomonas fluorescens strain (PfT-8) was capable of producing high levels of chitinase, β-1,3-glucanase, cellulase, fungitoxic metabolites and siderophores. Seven different carrier formulations...... hiện toàn bộ
