“…In all years background vector flight activity was monitored with two yellow water traps after Moericke (1950Moericke ( , 1955, which were placed on bare soil at each end of Expt A-D. Sticky black nets on aluminium frames (Heimbach et al, 2002) of 0.5 m by 0.5 m (mesh size 7.7 mm by 4 mm, water proof insect glue Soveurode ® , Witasek, Austria) were exposed c. 10 cm above the plant canopy in the centre of plots in presprouted Christa plots (Expt B) from 22 to 25 May 2001. In Expt A to D the percentage of aphid infested leaves was determined weekly to fortnightly by inspecting 99 leaves per plot, i.e.…”

“…Straw mulch has been well studied in reducing aphid infestation and virus incidence in several crops, such as barley (Kendall et al, 1991), faba bean (Heimbach et al, 2002), lupins (Jones, 1994), and rape (Heimbach et al, 2000(Heimbach et al, , 2001. Furthermore, straw mulch as an organic and relatively cheap material is also on-farm available in the required quantities.…”

Potato virus Y (PVY) is transmitted non-persistently by winged morphs of many aphid species and is a major problem in seed potato production. In order to evaluate the potential of straw mulch applications (4-5 t ha -1 ) and presprouting on PVY reduction, small scale organically managed field experiments were carried out in Northern Hessen, Germany, over 3 yr. In all years mulching significantly reduced aphid infestation on leaves as well as PVY incidence in tubers. For the effect of presprouting the temporal coincidence of two factors was crucial -crop emergence and aphid flight activity. Presprouting decreased PVY incidence when in the phase of early crop emergence aphid spring flight activity was low, but increased it, although not significantly, when prominent aphid flight peaks occurred in this critical period. Straw mulch was most effective when vector pressure was concentrated early in the year acting as a PVY protectant for young plants. In later growth stages its effect declined gradually with increasing ground coverage of the crop. Combined mulching and presprouting had a synergistic, complementary effect on reduction of PVY incidence. In an on-farm experiment in 2001 scaling up the area mulched stepwise from 100 m² to 900 m² consistently kept aphid infestation at reduced levels.

Soil conservation practices for insect pest management in highly disturbed agroecosystems – a review

Decline in soil health is a serious worldwide problem that decreases complexity and stability of agricultural ecosystems, commonly making them more prone to outbreaks of herbivorous insect pests. Potato (Solanum tuberosum L., Solanaceae) and onion (Allium cepa L., Amaryllidaceae) production is currently characterized by high soil disturbance and heavy reliance on synthetic inputs, including insecticides. Evidence suggests that adopting soil conservation techniques often (but not always) increases mortality and decreases reproductive output for the major insect pests of these important vegetable crops. Known mechanisms responsible for such an effect include increases in density and activity of natural enemy populations, enhanced plant defenses, and modified physical characteristics of respective agricultural habitats. However, most research efforts focused on mulches and organic soil amendments, with additional research needed on elucidating effects and their mechanisms for conservation tillage, cover crops, and arbuscular mycorrhizae.

“…Covering the soil between the rows of a crop with coloured plastic mulches has been known to reduce aphid infestation of the crop in numerous studies (Costello & Altieri, 1995;Heimbach et al, 2002;Silva-Filho et al, 2014;Koch et al, 2015). Mulches have also been shown to reduce the infection with aphid-transmitted plant viruses (Jones, 1991;Kirchner et al, 2014).…”

To test the behavioural response of winged aphid spring migrants to visual contrasts, we conducted a field trial in which water traps (painted in seven different shades of green and yellow) were set up on uncovered soil and on coloured boards (also painted in seven different colours including black, brown and various shades of green). In total, 56 trap-background combinations were tested. Out of the 4904 aphid individuals caught, 64.5% belonged to Aphis ssp. Using spectral measurements of both traps and backgrounds, as well as information on insect spectral sensitivity, an empirical colour choice model was built based on photoreceptor adaptation to the background, and colour opponency of the green and blue photoreceptor. Specifically, the visual input variable C* represents the difference between green-blue colour opponency values of the trap and the background. When C* > 0, the number of aphids linearly increased with C*. The model explained 64% of the behavioural response of the aphids. Applied to intercropping scenarios of sugar beet, the behavioural model showed a higher visual attractivity of a monocrop sugar beet than intercropped sugar beet. Implications for the use of mulches and for increasing plant diversity in cropping systems are discussed.
