Comparison of the biology of Myzus persicae Sulz. resistant and susceptible to dimethoate
, 1970 SUMMARY Apterous Myzus persicae resistant to dimethoate reproduce for the same length of time as susceptible aphids, but the resistant ones reproduce significantly faster during the first 10 days of adult life (especially during the first 5 days ...

Insect Science, EarlyView.The level of aggressiveness of an individual is a factor that shapes intraguild predation (IGP) interactions. In Nabis americoferus, high aggressiveness leads to an increase in attack rate and IGP against Harmonia axyridis. Moreover, the absence of extraguild prey seems to exacerbate IGP. In docile N.

Cytogenetic characterization of the holocentric chromosomes in the aphids Myzus varians and Myzus cerasi [PDF]
Caryologia, 1999 Cytogenetic investigations on the holocentric chromosomes of Myzus varians and Myzus cerasi have been carried out using silver staining and C-banding followed by chromomycin A3 (CMA3) and DAPI staining in order to improve our knowledge of these pest crop species and facilitate their identification. In M. varians C-banding pattern is pecu-: liar of each

Proinsecticides effective against insecticide-resistant peach-potato aphid (Myzus persicae (Sulzer))
, 1998 A range of potential proinsecticides was synthesised and tested against insecticide-susceptible and -resistant clones of Myzus persicae (Sulzer). They were all esters of compounds known to be toxic or pharmacologically active, and were designed to have ...

Aphid and endosymbiont sensitivity to heatwaves is misaligned across life stages
Insect Science, EarlyView.Aphids depend on the obligate symbiont Buchnera aphidicola, which may constrain thermal tolerance. Using a factorial heatwave experiment, we exposed nymphs and adults to moderate or extreme temperatures and measured fitness and symbiont responses.
