cabbage leaf miner scaptomyza flava (fallen) (l)iptera: drosophilidae) is a native and oligophagous leaf miner insect on cruciferous plants (brassicaceae). it occurs in many parts of the world and throughout khuzestan. the relationship between feeding and ovipositional preferences of insect, and host plant suitability on seven host plant species (cauliflower brassica oleracea var. botryds, ...

Experience is well known to affect sensory-guided behaviors in many herbivorous insects. Here, we investigated the effects of natural feeding experiences of Helicoverpa armigera larvae on subsequent preferences of larval approaching and feeding, as well as the effect of host-contacting experiences of mated females on subsequent ovipositional preference. The results show that the extent of exper...

A study on symptoms of damage and ovipositional preference tea mosquito bug (TMB), Helopeltis antonii Signoret was done guava, moringa neem. survey conducted in villages Dindigul Theni districts Tamil Nadu, India for observing damage. In the feeds both new flush fruits, causing irregular necrotic spots young leaves corcky out growths fruits. moringa, flowers dry-up give wilted appearance. neem,...

reproductive parameters and ovipositional preference of plutella xylostella were assessed on some mutant genotypes of canola (rgs 8-1, rgs 10-2, rgs 8-13, zar 9-9 and talaye 8-3) and their cultivars (rgs, zar, talaye) under greenhouse condition (21 ± 6 °c, 65 ± 10 rh and a photoperiod of 16l: 8d h). comparison of the reproductive parameters on rgs and its mutant genotypes revealed that mutant g...

Black vine weevils, Otiorhynchus sulcatus (Fabricius) (Coleoptera: Curculionidae), are globally-distributed polyphagous pests of many horticultural crops. We investigated how adult weevils were affected by host switching and, in particular, how host plant species nutritional and defensive chemistry affected subsequent host plant species selection and oviposition. Adults were fed one of three ho...

The present study was undertaken to verify ancient data in the literature on ovipositional preference o f the cuttlefish Sepia officinalis for the terrestrial plant Pistacia lentiscus (mastic tree). Adult specimens o f Sepia were placed in basins together with aerial parts not only of P. lentiscus, but also o f Artemisia arborescens, Centaurea alba var. deusta, Quercus ilex and Laurus nobilis. ...
