AbstractThe oviposition preferences of Lygus lineolaris (Palisot de Beauvois) were studied on Brassica carinata A. Braun, Brassica juncea (L.) Czern, Brassica napus L., Brassica rapa L., Sinapis alba L. (high glucosinolates), Sinapis alba L. (low glucosinolates), and Sinapis arvensis L. in a choice test during a 14-day period in field cages. Host-plant discrimination occurred on at least two levels. The first level occurred at the generic level; ovipositing females first selected species of Sinapis on which to lay eggs and later laid on species of Brassica. On species of Sinapis, 80% or more of the total number of eggs were laid during days 1–6, whereas only 35–58% were laid during this period on species of Brassica. The second level occurred at the species level in both Brassica and Sinapis. In Brassica, significantly more eggs were laid on B. carinata and B. napus than on B. juncea; in Sinapis, significantly more eggs were laid on S. alba (high glucosinolates) than on S. arvensis. The numbers of eggs did not differ significantly among B. carinata, B. napus, and S. alba (high glucosinolates). The numbers of eggs on B. rapa and S. alba (low glucosinolate) were not significantly different from those on the other five Brassica and Sinapis hosts tested. Host-plant selection seemed to be unaffected by glucosinolate levels in the seed of S. alba.

Choice Tests

AbstractIn tests in Nigeria with its principal host-plant, cowpea, Cydia ptychora (Meyr.) showed distinct oviposition preferences. Most of the eggs were laid on the sepals (including their remains on pods) in screenhouse tests involving four varieties. There were distinct differences in the number of eggs laid on different varieties in both no-choice tests with four or five varieties and free-choice tests with 17 varieties in the field. Vita-3 was the preferred variety in the laboratory tests and H 13–1 in the larger comparisons in the field. Fewest eggs were deposited on Tvu 2994 in all tests.

Oviposition Sites

We studied the behavior and oviposition preferences in Aporia crataegi. The study was conducted in a network of dry karst meadows with hedgerows consisted mainly of host plants (Crataegus monogyna; Prunus spinosa, Prunus mahaleb, Rosa sp.) between them. We recorded 15 different behaviours that we divided into six categories: (1) behaviours connected to flight (9 different behaviors), resting (2 behaviors); and (3) feeding, (4) courtship, (5) copula and (6) oviposition with one behaviour each. Males proved to spend most of their time on wings patrolling, while females were more sedentary, but still actively flying and searching for nectar sources and oviposition sites. Differences in behaviour between the sexes were less prominent during the morning but increased during the midday and afternoon, as the males became more active but females were resting and feeding more, probably after searching for host plants and egg-laying earlier in the day. Most commonly, C. monogyna was chosen for oviposition by females, but we found a single oviposition site on P. mahaleb as well. Females lay their eggs in clusters of an average size (AVG±SD/SE) of 34.4±12.8/2.05 eggs, and from a single to up to seven oviposition sites were recorded per host plant. Since the number of eggs in each recorded plant with four or more oviposition sites exceeded an upper limit of eggs laid by a single female reported in literature, females either can lay more eggs or more than one female chose the same host plant. Occupied host plants had similar characteristics as the ones occupied with larvae; females preferably choose smaller shrubs, exposed to the sun with a high percentage (>50%) of a leaf litter coverage underneath them.
