CONTROL OF MELON APHID AND CITRUS MEALYBUG ON CHRYSANTHEMUM UNDER GREENHOUSE CONDITIONS, FALL 1998

lethal and sublethal effects of imidacloprid and pirimicarb on the melon aphid, aphis gossypii glover (hemiptera: aphididae) under laboratory conditions

the toxicity of imidacloprid and pirimicarb for all stages of the melon aphid, aphis gossypii glover, were investigated under laboratory conditions (25 ± 1 oc, 65 ± 5% r.h. and a photoperiod of 16:8 (l: d) h.) using a leaf dipping method. these pesticides were very toxic for first instar nymphs of a. gossypii with lc50 values of 17 and 220.2 ppm for imidacloprid and pirimicarb, respectively. fo...

Effect of amino acid and mycorrhiza inoculation on sweet pepper growth under greenhouse conditions

ABSTRACT- The production of greenhouse sweet pepper is increasing because of the consumer demand for sweet pepper year around. In this study, physiological characteristics of sweet pepper were evaluated in a greenhouse under different levels of arbascular mycorrhizal fungus, Glomus intraradices, (AMF) and various levels of amino acid (AA). Treatments included no AMF as a control (AMF1), 1000 sp...

study on morphological, molecular and biological characteristics of the conifer aphid, cinara pini linnaeus (1758) (hem.: lachnidae) under greenhouse conditions

during a survey on pests of pine trees, pinus mugo turra, in april 2010 in mashhad, a colony of an aphid was observed in abundant populations on the seedlings, belongs to the subfamily cinarinae and family lachnidae, being identified as cinara pini (linnaeus, 1758). the blast sequence to c. pini in the gene bank showed that the species was most similar to c. atlantica with 93% similarity. the m...

Natural hosts of russian wheat aphid diuraphis noxia (mordvilko)(homoptera: aphididae) in the fars province (iran) and a preference test for the grasses under greenhouse conditions

an evaluation of lethal effects of pirimicarb, citowett oil and their mixture on greenhouse whitefly (trialeurodes vaporariorum) and green peach aphid (myzus persicae) under greenhouse conditions

susceptibility of eggs, nymphs and adults of greenhouse whitefly (trialeurodes vaporariorum westwood) and adults of green peach aphid (myzus persicae sulzer) to pirimicarb (pirimor®) and citowett oil alone vs. in combination was evaluated under greenhouse conditions. the glass vial and leaf dipping methods were employed for bioassay of adults vs. the immature stages (egg, nymph and pupa) of gre...
