“…Statistical variables, including net reproductive rate and intrinsic rate of natural increase, are valid criteria to determine aphid performance. Plants on which aphid populations have a lower intrinsic rate of increase and a lower rate of reproductively are more resistant than plants on which aphid populations show a higher rate of increase (Zarpas et al 2006). In general, our results in accordance with those provided by Adly and El-Gantiry, (2014), who stated that the total mortality percentage of A. illinoisensis was high (75.0%) at 20 and 25 o C on the grape variety (Superior).…”

The effect of temperature on certain biological aspects and fertility life table of the grapevine aphid as a key of abiotic factor has been investigated. The experiments were conducted at four constant temperatures 17, 21, 24 and 27°C, 65 ± 5 % R.H. and 14 hrs. photophase. The tested individuals were reared and observed on young shoots of Vitis vinifera (Superior variety). The data revealed that aphids developed faster with increasing temperatures within the 17 -27 °C range. The grapevine aphid passed through four instars before reaching maturity. The nymphal development period varied significantly between temperatures, they lasted 15.5, 12.2, 7.3 and 5.4 days at 17, 21, 24 and 27°C, respectively. The theoretical lower developmental threshold (t 0 ) was 12.4 °C and 80.73 day-degrees were required for aphids to reach adulthood. The life table parameters differed at the tested temperatures. These parameters clarified the temperature effect on A. illinoisensis biology, where the largest R o, λ and r m were 6.30, 1.155 and 1.088 at 24, 24 and 21 °C, respectively. The range of generation time values (GT) recorded 27.39-10.53 days at the tested temperatures. As a result from the aspect of development and fecundity, A. illinoisensis had the best performance on 24°C and the worst on 17 and 27°C.

“…However, leaf trichomes can mechanically disrupt the movement of insect herbivores on the leaf surface, thus reducing access to the food. Leaf hairiness was partly responsible for the poorer performance of cotton aphid on some cotton and okra varieties [ 70 , 71 ]. For this reason, the hairy cultivars were used for their higher resistance against various insects on cotton, wheat, and soybean [ 53 ].…”

Resistance and tolerance of ten carrot cultivars to the hawthorn-carrot aphid, Dysaphis crataegi Kalt., in Poland

Damage caused to cultivated carrots by the hawthorn-carrot aphid, Dysaphis crataegi Kalt. (Hemiptera: Aphididae) is one of the factors limiting carrot production in Poland. Planting resistant and tolerant cultivars could reduce yield losses due to the damage caused by this pest. This study was conducted to evaluate the resistance and/or tolerance of 10 carrot genotypes to hawthorn-carrot aphid. Their field resistance was determined under field conditions based on five indicators, namely, mean number of alates (migrants) per plant and mean percentage of plants colonized by them, mean seasonal number of aphids per plant, mean number of aphids per plant and mean percentage of infested plants at peak abundance. Antibiosis experiments were conducted under laboratory conditions and pre-reproductive, reproductive time, fertility, and demographic parameters, represented by the net reproduction rate (Ro), intrinsic rate of increase (rm) and mean generation time (T), were calculated. Five cultivars, Afro F1, Nipomo F1, Samba F1, White Satin F1, and Yellowstone showed field resistance. Antibiosis experiments revealed significant differences among the carrot cultivars in the length of the reproductive period, female fecundity in the time equal to the pre-reproduction time, and total progeny of hawthorn-carrot aphid. The intrinsic rate of natural increase (rm) for apterous aphids varied significantly, ranging between 0.181 (Nipomo F1) and 0.343 females/female/day (White Satin F1). Additionally, the estimated net reproductive rate (R0) was the lowest on Nipomo F1, and this genotype was determined to be resistant. Our results suggest that a very high density of trichomes on the leaf petioles (71.94 trichomes/cm2) could adversely affect the feeding, bionomy, and demographic parameters of hawthorn-carrot aphid on the cultivar Nipomo F1. In addition, Napa F1 and Kongo F1 demonstrated high tolerance. Considering all the results collectively, four genotypes, Afro F1, Kongo F1, Napa F1 and Nipomo F1, were relatively resistant/tolerant to the hawthorn-carrot aphid.

In this article, the biology and fertility life table parameters of the cabbage aphid, Brevicoryne brassicae (L.) (Hemiptera: Aphididae), were studied on cauliflower leaves, Brassica oleracea var. botrytis (Brassicales: Brassicaceae), of the cultivars Smilla, Snow mystique, White cloud, Buris, Galiblanka, Snow crown, SG, and Tokita. This study was conducted under controlled conditions: 25 ± 2°C, 65 ± 5% relative humidity (RH), and 16:8 (L:D) h photoperiods. Statistical analysis showed that there was a significant difference ( P < 0.05) between the different growth stages and the mean number of laid nymphs. Further, the maximum and minimum growth periods were observed on Galiblanka and Buris cultivars, respectively. The shortest nymphal instar growth period was observed on the Smilla cultivar (6.70 d), and the longest lifespan was seen on the White cloud (8.10 d). The Smilla cultivar (39%), in an adult emergence stage, and the SG (88%) revealed the lowest and highest rates of survival, respectively. Aphids reared on the Smilla cultivar were found to have increased due to the high intrinsic ( rm ) and finite (λ) rate of increase and the low doubling time (DT). The results indicated that the application of cultivars affecting adult reproductive parameters could be a good solution to cabbage aphid control management.
