“…Eggs were laid singly and in clusters on adaxial surfaces of intact and wax-free common cabbage leaves (leaf 6). Wax crystals were removed from the adaxial surface of number-6 leaves by dipping a piece of cellulose acetate (25 µm thick) into absolute acetone solution and immediately placing it on the selected leaf surface (Cribb et al, 2010). When the cellulose acetate sheet dried (after ca.…”

Oviposition patterns of the diamondback moth (DBM), Plutella xylostella L. (Lepidoptera: Plutellidae), differ between common cabbage (Brassica oleracea L. var. capitata) and Chinese cabbage (Brassica rapa L. var. pekinensis) (Brassicaceae) host plants. This study shows that the moth prefers to oviposit on adaxial rather than abaxial leaf surfaces and petioles of both host plants. More eggs were laid in leaf veins than on leaf laminas of both host plants, especially in Chinese cabbage, where 94.6% of eggs were laid in veins. On Chinese cabbage, very few eggs were laid in clusters (≥2 eggs), whereas on common cabbage approximately 30% of eggs were laid in groups of 2 or more eggs. Removal of wax from common cabbage leaves dramatically increased the number of eggs laid singly on the leaf lamina of treated plants, suggesting that leaf waxes affect how eggs are distributed by ovipositing DBM. Eggs were most susceptible to removal by rainfall from the plant surface immediately (<1 h) after oviposition and when close to hatching (>72h old) whereas they were least susceptible 24 h after oviposition. Eggs laid on common cabbage plants were more susceptible to simulated rainfall than eggs laid on Chinese cabbage plants. On common cabbage plants, egg susceptibility to rainfall on different plant parts ranked adaxial leaf surfaces>petioles = abaxial leaf surfaces>stem, but there was no difference in egg susceptibility to rainfall on the various plant parts of Chinese cabbage. Furthermore, on common cabbage plants, eggs laid on both adaxial and abaxial leaf surfaces were afforded significant protection from the effects of rainfall by leaves higher in the plant canopy. On common cabbage plants, oviposition patterns reduce the potential impact of rainfall on eggs, possibly reducing the effect of this important abiotic mortality factor in the field.

“…Small newly hatched larvae perceive and are impacted by the plant in ways that may not affect them when larger. For example, cuticular lipids and waxes in new leaves may deter feeding by early instars, but be appropriate for later instars (Eigenbrode & Espelie, ; Cribb et al., ). So far, most work on intraplant performance has focused on trees (e.g., Schultz, ; Crawley & Akhteruzzaman, ; Morrison & Quiring, ), whereas less attention has been given to annual plants and agricultural systems.…”

Host utilization is mediated by movement of pre‐feeding Phthorimaea operculella larvae in the Nicotiana tabacum agroecosystem

The distribution of insect herbivores within their hosts can be influenced by insect preference, plant characteristics, and biotic interactions such as refuge from predation. We observed significantly more Phthorimaea operculella (Zeller) (Lepidoptera: Gelechiidae) larvae in the lower portion of commercial tobacco plants, Nicotiana tabacum L. (Solanaceae), an occasional host, and sought to explain this distribution pattern. Phthorimaea operculella are oligophagous leaf miners of solanaceous plants, including cultivated crops. Females lay their eggs in the soil beneath N. tabacum plants rather than on the foliage, forcing newly hatched larvae to search for host tissue. We hypothesized that P. operculella larvae were establishing in the lower portion of N. tabacum plants because either they gained a performance advantage, or it was the first suitable leaf material contacted. To measure within‐plant larval performance, neonates were released in cages on leaves in the upper, middle, and lower stalk positions of the plant before and after the plant flowered. Phthorimaea operculella performed significantly better on younger plants and in the top leaves. To test larval ability to move within and between plants, we removed leaves at four heights to increase the distance newly hatched larvae must travel. Larval establishment was highest on plants with no leaves removed, but larvae were able to move an average distance of over 70 cm from release point to host leaves in plants directly above the release point and adjacent plants. Phthorimaea operculella larvae appear to utilize suboptimal N. tabacum host tissue to maximize their chances of survival.

“…Although there is evidence showing a significant relationship between host plant architectural characteristics and behaviour of fruit flies, the fundamental scientific questions of how fruit flies optimise their search patterns and limit competition through movement choices and how these movement patterns are affected by plant architecture are still not well understood. There is evidence that underlying rules for generating insect movement behaviour patterns in plant canopies may be simple and generic, based largely on plant architecture and some simple insect behavioural rules (Cribb et al, 2010;Perkins et al, 2010;Perkins et al, 2008;Perkins et al, 2009). If we hypothesize that spatial patterns of insect populations in plant architecture emerge from behaviour of individual insects, IBM can then be used to better simulate the studied system (Vinatier et al, 2011).…”

A form of agent-based modelling known as individual-based modelling has been used widely to simulate hypothesised mechanisms underlying processes in the real world, especially in the field of behavioural ecology. To apply this approach to insect-plant interactions the Queensland fruit fly (Qfly), Bactrocera tryoni (Froggatt) (Diptera: Tephritidae), a major native insect pest of horticulture in Australia, will be examined. Due to restriction on use of some chemicals, currently there is no suitable management system for control of Qfly. However, better Qfly management can be potentially advanced by targeted behavioural, physiological and ecological research on this species. Many control options depend on behavioural fundamentals of Qfly such as foraging and movement patterns (e.g. trapping control technique), and the use of resources like protein and food sources (e.g. bait spray control technique).
