“…Similar within-plant distributions have been reported for other aphid species such as Myzus nicotianae Blackman and M. persicae (Sulzer) on flue-cured tobacco (Lampert 1989) where aphids were most abundant in the middle third of the plant, M. persicae on potato (Jansson & Smilowitz 1986) where aphids were consistently more abundant on the lower leaves, Pentalonia nigronervosa (Coquerel) on banana mats (Hooks et al 2011) where aphids were rarely found ≥2.5 m within the plant canopy, and Aphis craccivora Koch on alfalfa (Berberet et al 2009) where the greatest number of aphids where located in middle and lower portions of the plant canopy.…”

A field trial was performed on a hop yard throughout 2006, 2007 and 2008 in order to analyze the within‐plant distribution of Phorodon humuli (Schrank) and its natural enemies. The aphid population was higher on the leaves of the middle section of the main stem. Specifically, the population was significantly higher at 2 and 3.25 m than at 6 m during the three years. Natural enemies consisted of aphidophagous predators of which Coccinella septempunctata was recorded in the highest number. Its number was greater where the aphid population was higher, with a significantly higher number of eggs, larvae and adults at 2 and 3.25 m than at 6 m. Lacewing eggs were also frequently observed, with a significantly higher population where the number of aphids was higher. The number of winged aphids was higher at 3.25 m than at 2 m within a plant. Understanding hop aphid distribution within the hop canopy is important in developing sampling programs, in evaluating injury and helps the development of sustainable management practices.

“…In addition, a survival and fecundity table was constructed, from which the net reproduction rate ( R o : corresponding to the total fecundity per surviving aphid in this work), intrinsic rate increase ( r ), regeneration time ( T ), and the doubling time (DT) were determined (Hance et al 1994). In order to prevent aphids and/or nymphs from moving and hiding in other parts of the plant (e.g., spaces between the pseudostem sheaths), and to facilitate handling, aphids were placed at the base of the pseudostem, and a parafilm paper device, surrounded by sticky paper, was rolled up 20 cm from the neck of each banana plant; this approach was based on the fact that P. nigronervosa prefers to settle at the base of the banana plants, close to the ground, when aphid numbers are still low (Robson et al 2006, Hooks et al 2011). The whole set-up (banana plant–cage–aphids) was placed in an air-conditioned room, at a temperature of 25 ± 2 °C, a relative humidity of 40 ± 5%, and an artificial photoperiod of 12/12h.…”

Viral diseases can change plant metabolism, with potential impacts on the quality of the plant’s food supply for insect pests, including virus vectors. The banana aphid, Pentalonia nigronervosa Coquerel, is the vector of the Banana bunchy top virus (BBTV), the causal agent of Banana bunchy top disease (BBTD), the most devastating viral disease of bananas in the world. The effect of BBTV on the life-history traits and population dynamics of P. nigronervosa remains poorly understood. We therefore studied the survival rate, longevity, daily fecundity per aphid, tibia length, population growth, and winged morph production of a P. nigronervosa clone grown on healthy or infected, dessert, or plantain banana plants. We found that daily fecundity was higher on infected banana than on healthy banana plants (plantain and dessert), and on plantain than on dessert banana plants (healthy and infected). Survival and longevity were lower on infected dessert bananas than on other types of bananas. In addition, virus infection resulted in a decrease in aphid hind tibia length on both plant genotypes. The survival and fecundity table revealed that the aphid net reproduction rate (Ro) was highest on plantains (especially infected plantain), and the intrinsic growth rate (r) was highest on infected plants. Finally, the increase of aphids and alate production was faster first on infected plantain, then on healthy plantain, and lower on dessert banana (infected and uninfected). Our results reinforce the idea of indirect and plant genotype-dependent manipulation of P. nigronervosa by the BBTV.

“…As plants become larger or older, there will be a pronounced increase in the abundance of rewards; this can lead to reduced herbivory and enhanced fitness (Quintero et al 2013). The aphid density on plants also can vary with plant size, with higher density on smaller individuals, or smaller (younger) branches within a plant (Hooks et al 2011). Therefore, it is reasonable to predict that the ant-plant interaction mediated by aphids also can vary with plant size.…”
