Epilachna Dodecastigma

An experiment was carried out to study the effect of temperature on biology, oviposition and feeding behaviour as well as host preference of Epilachna beetle, Epilachna dodecastigma (Wied.) on eight varieties of brinjal, Solanum melongena Linn. from November, 2009 to June, 2010 maintaining controlled temperatures of 15ºC, 25ºC and 30ºC using an incubator in the Department of Entomology, BAU, Mymensingh. Temperature has a profound influence on the oviposition and food consumption of Epilachna beetle. In incubator at 15oC, 25oC and 30oC temperature, larval daily average food consumption (mm2) among eight   host plant varieties of S. melongena was the highest on Thamba and the lowest on Bijoy, whereas adults daily mean food consumption at three temperature regimes was the highest on Thamba and the lowest on BAU-2 at 15oC and 25oC temperature and at 30oC temperature the lowest recorded on Bijoy. At 25oC temperature, the highest oviposition was recorded on Thamba and the lowest found on Jhumki. Similarly at 15oC and 30oC temperature, the highest oviposition was also observed on Thamba and  the lowest on Bijoy. Thus, the varieties namely Thamba, ISD 006 and Kazla appeared to be preferable hosts, whereas Bijoy, BAU-2 and Jhumki seemed to less preferable. The results revealed that temperature had direct effect on the behaviour and 25°C  temperature was congenial to both fecundity and food consumption of the Epilachna beetle.

Aromatic Herbs

Colombian aromatic herbs have great potential as an export commodity. The genus Copitarsia is considered as an economic and a quarantine pest attacking them. In herbivore insects, host plant choice is made by adults and influenced by host plant quality. There were performed olfactory and feeding tests by using four-arm olfactometer and offering four different aromatic herbs (basil, mint, rosemary, or thyme) to determine the host selection behavior of Copitarsia uncilata Burgos and Leiva. Parameters, such as adult choice, larval weight, and time spent by larva on particular herb were measured. The preferences of adults and immature of C. uncilata varied significantly among the herbs in olfactory and larva feeding tests. The adults showed significantly higher responses to essential oils of basil and rosemary. Higher weight of larva was recorded on mint and basil. Further studies on larval development and longevity of adults on different herbs are necessary.

Penetration Behaviour

Carystoterpa fingens (Walker) is an endemic xylem feeder It was chosen as a model insect for the glassy winged sharp shooter (Homalodisca coagulata (Say)) The electrical penetration graph (EPG) technique was used to measure realtime stylet penetration and feeding behaviour of 48 adult C fingens on four plant types hebe (Hebe pubescens) rengarenga lily (Arthropodium cirratum) wild iris (Dietes bicolor) and cabbage (Brassica oleracea) over 12 days EPG waveforms were recorded for 12 hours and the duration of the main penetration events (pathway ingestion and nonprobing phases) of the insects were analysed to compare host preferences There were no significant differences in the duration of ingestion indicating that all the plants were potential hosts for C fingens Insects on hebe showed the shortest nonprobing time suggesting that hebe was the most preferred host as expected from observations in the wild
