In agrosystems, pests are submitted to strong human-imposed selective pressures to which they sometimes adapt rapidly, either through selection of genotypes resulting from mutation and ⁄or recombination events, or through phenotypic plasticity. Understanding how insects respond to such selective pressures is of great importance for sustainable pest management strategies, such as the use of resi...

bionomics of aphis gossypii glover and its predators coccinella septempunctata l. and hippodamia variegata goeze were studied in varamin (tehran province) during 11th may to 5th october 2006 on eggplant crop, with the interaction (density dependence) between the aphid and either of the predators determined. the reliable sample size (number of leaves) with a maximum variation of 6.73% was about ...

Banker plants with Aphidius colemani Viereck were tested in greenhouses in Massachusetts and New York for control of cotton aphid Aphis gossypii Glover, and green peach aphid Myzus persicae (Sulzer) on 2 spring flower crops, pansies ( Viola tricolor hortensis ) and Marguerite daisies ( Argyranthemum hybrid). Banker plants consisted of pots of barley plants infested with the bird cherry-oat aphi...

Fertilization levels for ornamental crops may influence pest population dynamics, crop quality, and pest management strategy. We examined the effect of fertilization on population growth and within-plant distribution of melon or cotton aphid, Aphis gossypiiGlover, on potted chrysanthemum, Dendranthema grandiflora (Tzvelev). In terms of pest management implications, we also investigated the effe...

aphis gossypii glover is one of the most important pests of greenhouse cucumber and pepper in the world and iran. in this research, life table and biology of a. gossypii were investigated on cucumber (cucumis sativus cv. super sultan) and pepper (capsicum annum cv. marqueza) in a growth chamber at 25±1°c and 60±5% rh and a photoperiod of 14 l: 10 d hour.the results showed thatdevelopmental time...

La gestion des insectes ravageurs du cotonnier (Gossypium hirsutum) a toujours été émaillée par l’emploi répété de produits chimiques synthèse, avec effets néfastes sur l’environnement. Pour ce faire, une étude comparative portant différents modes d’association menée en vue d’apporter nouvelles stratégies biocontrôle cotonnier. L’essai conduit plein champ à Katibougou au Mali un dispositif bloc...
