“…Eulophids are considered mainly hyperparasitoids (Norman et al, 1996), and therefore it is hypothesised that this could be a strategy for these parasitoids to be active at a later part of the day (with higher light intensity), in order to successfully parasitise the primary parasitoids (braconids, ichneumonids and chalcids), which have been actively ovipositing during the earlier part of the day. This current study also supported the previous report by Idoine and Ferro (1990) which indicated that the egg parasitoid eulophid, Edovum puttleri are active at around mid-day to the afternoon, i.e. between 6-11 hr after sunrise.…”

Bagworms (Lepidoptera: Psychidae) are one of the important leaf-eating pests of oil palm in Malaysia and Indonesia. Crop losses, due to the extensive defoliation by a serious bagworm attack are inevitable. The establishment and propagation of the bagworm's parasitoids, depend very much on species of flowering plants as sources of nectar. Cassia cobanensis, was proven suitable due to its attractiveness to most bagworm parasitoids. A study to assess the diversity of bagworm's natural enemies (hymenopterous parasitoids and reduuvid predatory bugs) on the C. cobanensis plant and within the undergrowth of the oil palm planting block was evaluated by sweep net and sticky trap sampling. Environmental parameters such as light intensity, temperature and relative humidity were also recorded during the sampling to determine their possible range of influence towards the activity of the insect natural enemies. The Shannon-Wiener diversity index of insect natural enemies occurring on the C. cobanensis plant was 2.32. Among the dominant parasitoids observed on C. cobanensis plants are chalcids (Brachymeria lugubris and Brachymeria carinata) and braconids (Dolichogenidea metesae and Apanteles aluella), besides the reduuvid predator, Cosmolestes picticeps. In contrast, within the oil palm planting block, the undergrowth within the non-harvesting path only recorded a much lower diversity index of 1.09 and 1.12 each, in a block with C. cobanensis at the roadside and without, respectively. However, C. picticeps was shown to be much more dominant within both oil palm planting blocks, up to two-to threefold , with much lesser numbers of hymenopterous parasitoids (less than five individuals). This indicates the important contribution of C. cobanensis plant towards enriching the diversity of the parasitoids, which are normally not found within the oil palm block, due to much less intense sunlight. In terms of insect activity, they are significantly more active in the moderate or medium light intensities (<8000 fc), medium humidity levels (50%-69%) and medium temperatures (30°C-34°C).

“…Goldson et al (1990) showed that aestivating S. discoideus were not attacked by M. aethiopoides, again indicating host movement is an essential cue to initiate stalking by the parasitoid, and eventually oviposition. Mityakina et al (1993) and Idoine and Ferro (1990) showed a similar diurnal pattern of oviposition by the egg parasitoid Edovum puttleri in the Colorado potato beetle, where no oviposition occurred during the dark period or early light period.…”

Laboratory experiments were carried out to investigate the circadian patterns of oviposition of the parasitoids Microctonus aethiopoides Loan and M. hyperodae Loan in their respective hosts Sitona discoideus Gyllenhal and Listronotus bonariensis (Kuschel). Successful oviposition by M. aethiopoides in S. discoideus occurred more frequently during light than during dark periods, but M. hyperodae achieved higher parasitism levels in L. bonariensis during hours of darkness than during light. Circadian parasitoid oviposition activity was related to host activity, measured by feeding and oviposition. S. discoideus was found to feed and lay eggs mostly during the latter part of the light period, whereas L. bonariensis feeds mainly after dark.

“…Parasitoid releases had greater impact on 2 nd generation eggs. Sears & Boiteau (1989) viewed this as largely a matter of the parasitoid's response to temperature and its inability to effectively parasitize hosts at temperatures below 17 ~ However, ldoine & Ferro (1990) showed E. puttleri to forage principally in the afternoon (12 : 00-16 : 00 EST) for host eggs, a period when temperatures in the field during the 1 st egg generation in Massachusetts are above 21 *C. An alternate explanation for E. puttleri's poor performance against the 1 st beetle generation in northern parts of the U.S. may be that adult E. puttleri wasps require a carbohydrate source and none is available during this period (Idoine & Fen'o, 1988). Early season potato fields in Massachusetts are not colonized by aphids (the principal potential carbohydrate source in potatoes) until July.…”

Release of approximately 17,700 experienced adult female Edovum puttleriGrissell against I st generation Colorado potato beetle eggs in 1987 in a 0.4 ha potato field in S. Deerfield, Massachusetts resulted in only 3.6 % parasitism as assessed by direct measurement of host and parasitoid recruitment. Levels of .non-viability indicated an additional 2.8 % of hosts killed by parasitoid hostfeeding, for an overall impact of 6.4 %. Release in 1988 of 126,300 parasitoid against 1 st generation hosts in a 0.4 ha potato (Solanum tuberosum L.) field at the same site produced only slightly higher levels of parasitism (10.6 %) and host feeding (2.0 %).Release in 1987 of 32,800 wasps against 2 na generation eggs resulted in only 0.7 % l~arasitism and 0.3 % host feeding due to the toxicity of fenvalerate (Pydrin ~) residues from a single application applied for control of the potato leafhopper, Empoascafabae (Harris). Release in 1988 of 47,400 wasps against the 2 "d host generation in the absence of any pesticide applications resulted in 34.4 % parasitism and 16.1% host feeding, for a total impact of 50.5 %. Difference in parasitization levels between host generations supports the idea that E. puttleri adults require an in-field carbohydrate source such as aphid honeydew to reproduce. In Massachusetts, aphid populations in potato typically do not develop until the end of the 1 St larval generation.The recruitment method of Van Driesche & Bellows (1988) proved to be a satisfactory approach for determining results of augmentative parasitoid releases.
