During greenhouse production in Spring 1995, conditioning treatments were applied to columbine (Aquilegia ×hybrida Sims ‘McKana Giants’), New Guinea impatiens (Impatiens hawkeri Bull. ‘Antares’), marigold (Tagetes erecta L. ‘Little Devil Mix’) and ageratum (Ageratum houstonianum Mill. ‘Blue Puffs’) plants. Treatments included: mechanical conditioning (brushing 40 strokes twice daily); moisture ...

Red imported Þre ants, Solenopsis invicta (Buren) (Hymenoptera: Formicidae), are an invasive species found in high densities throughout southeastern agricultural systems. We tested the hypothesis that Þre ants tend cotton aphids, Aphis gossypiiGlover (Homoptera: Aphididae), and thus release them from predation by lady beetle larvae, Coccinella septempunctata L. and Hippodamia convergens Guerin-...

There is an increasing requirement to breed durable resistances to woolly apple aphid (WAA) into apple cultivars. Genetically diverse apple plantings have been established in New Zealand with one aim to identify new sources of resistance to this pest, and also to allow the computation of parameters of genetic interest. Such computations are hindered by the uneven distribution of the pest in the...

In Arabidopsis thaliana, PHYTOALEXIN DEFICIENT 4 (PAD4) functions as a key player in modulating defence against the phloem sap-feeding aphid Myzus persicae (Sülzer), more commonly known as the green peach aphid (GPA), an important pest of a wide variety of plants. PAD4 controls antibiosis and antixenosis against the GPA. In addition, PAD4 deters aphid feeding from sieve elements on Arabidopsis....
