Searching behavior and time budgets of the predator Podisus maculiventrisEntomologia Experimentalis et Applicata - Tập 60 Số 1 - Trang 83-93 - 1991
Robert N. Wiedenmann, Robert J. O’Neil
AbstractSearching behavior of the predaceous insect Podisus maculiventris (Say) (Heteroptera: Pentatomidae) was investigated in the laboratory to verify assumptions made in a predator search model. Female predators were placed into an arena containing 30 lima bean plants (Phaseolus lunatus L.), each having five ...... hiện toàn bộ
Effect of plants on the searching efficiency of a generalist predator: the importance of predator‐prey spatial associationEntomologia Experimentalis et Applicata - Tập 83 Số 1 - Trang 1-10 - 1997
Moshe Coll, L. A. Smith, Richard L. Ridgway
AbstractIn most studies of tritrophic interactions, the effect of plants on predators is confounded with changes in prey and predator behaviors after an encounter event. Here, we estimate how the effect of plants on prey distribution (in the absence of the predator) and on predator foraging behavior (in the absence of prey) may influence predation rate of ... hiện toàn bộ
ACCLIMATIZATION TO COLD IN INSECTS1Entomologia Experimentalis et Applicata - Tập 3 Số 1 - Trang 27-37 - 1960
E. H. Colhoun
Evidence is given that insects acclimatized to colder temperatures are more resistant to immobilization by cold. There is a temperature below which further acclimatization is not achieved. Data are presented for the rate of gain and loss of cold tolerance. This is further evidence of acclimatization. The rate of recovery after immobilization by cold is related to th...... hiện toàn bộ
CHILL‐COMA AND COLD DEATH TEMPERATURES OF APIS MELLIFERAEntomologia Experimentalis et Applicata - Tập 3 Số 3 - Trang 222-230 - 1960
J. B. Free, Yvette Spencer‐Booth
Worker bees have a lower chill‐coma temperature than drones or queens, which is influenced by their acclimatisation temperature as is their food consumption at a given temperature. Most bees die after 50 hrs. in chill coma, and survive longer at 5° C than at 0 or 10° C. Cold death occurs between −2 and −6° C and is unaffected by acclimatisation. Winter bees have low...... hiện toàn bộ
Experimental induction and termination of non‐reciprocal reproductive incompatibilities in a parahaploid miteEntomologia Experimentalis et Applicata - Tập 87 Số 1 - Trang 51-58 - 1998
Denise L. Johanowicz, Marjorie A. Hoy
AbstractTwo experiments were conducted to investigate the relationship between rearing temperatures, the presence or absence of Wolbachia endosymbionts, and non‐reciprocal reproductive incompatibility in inbred lines of the parahaploid phytoseiid mite Metaseiulus occidentalis (Nesbitt) (Acari: Phytoseiidae).... hiện toàn bộ
Response of predatory mites with different rearing histories to volatiles of uninfested plantsEntomologia Experimentalis et Applicata - Tập 64 Số 2 - Trang 187-193 - 1992
Junji Takabayashi, Marcel Dicke
AbstractThe behavioural response of the predatory mite Phytoseiulus persimilis to volatiles from several host plants of its prey, spider mites in the genus Tetranychus, was investigated in a Y‐tube olfactometer. A positive response to volatiles from tomato leaves and Lima bean leaves was recorded, whereas no res...... hiện toàn bộ
