Abstract:

The cotton leafperforator (CLP) Bucculatrix thurberiella Busck. is a sporadic pest in cotton fields of southwest desert area. The cotton leafperforator sex pheromone was identified and synthesized by Hall et al. (1992), thus providing a sensitive method for detecting CLP moths. Tests were conducted in 1992 and 1993 to determine the effective life of CLP polyethylene pheromone dispensers, correlate CLP male moth catches to cotton field infestations, determine the seasonal distribution, and effect of trap height on moth catches. The polyethylene pheromone dispensers were effective for about 4 we

Abstract:

Investigations were made into the trapping biology of the pitchers of Nepenthes rafflesiana (Jack), Family Nepenthaceae, in Brunei, Borneo. The plant produces two distinct pitcher forms, upper and lower, which were found to differ in their prey spectra. Although ants were the most important prey in both forms, the upper form caught more anthophilous insects than the lower. High contrast U/V patterns on the upper pitchers were found to contribute to the attraction of some anthophilous insects, as was the fragrance of upper pitcher fluid. Increased height above ground was also found to increase

The risk of corn rootworm damage to continuously-grown corn was assessed in 32 fields from seven counties in Virginia in 1993 and 1994, Approximately 28% of the fields examined had economic root damage in corn left untreated with a soil insecticide. In addition, 190/0 of the fields overall had an economic loss in silage due to corn rootworm damage. A second study evaluated the effectiveness of using adult corn rootworm counts on commercial Olson yellow sticky traps and ear-zone regions of corn plants to predict subsequent damage to corn. Regression models for each sampling method were used

Abstract:

The 1985 and 1986 Cotton Reports have the same publication and P-Series numbers.<br>Four trap types were used to trap boll weevils at 1 m heights, with and without grandlure, and 2 trap types were compared at 0.5 m height, with and without grandlure. The results indicate trap height may be an important factor in boll weevil catches at certain times during the cotton season. Also trap color, design and other factors may influence trap catches since traps not baited with grandlure caught high numbers of boll weevils during certain times during the cotton growing season.

A second year of field experiments was completed in 1999 at MAC that explored the potential of using a melon trap crop to reduce whitefly infestations in cotton. The experimental design was altered from 1998 to gain isolation among treatment blocks by using 4 separate fields that helped to avoid the influence of one treatment upon the other. A consistent response of significantly fewer whiteflies in cotton planted within a surrounding melon trap crop, relative to the same area of cotton without the trap crop, was observed throughout the July- September sampling period.

Abstract:

Trap crops were employed against the pink bollworm (PBW) as a part of a community-wide IPM program in Pima County, AZ. Levels of PBW larvae in the early squares of the trap crops were extraordinarily high, indicating that the trap crops were drawing overwintered PBW moths in from wide areas. This concentrated the overwintered moths in small areas where they could be easily and economically destroyed.

Abstract:

Trap crops were evaluated as a part of a community -wide pink bollworm (PBW) control program. We measured extraordinarily high numbers of PBW larvae in the trap crops in 1992, which indicated that the trap crops were attracting PBW moths from wide areas. However, we have no direct way of measuring any effect this would have on the main crop. Overall PBW populations were very low in 1993. While PBW numbers drastically declined in the community, this study offers no conclusive evidence as to whether trap crops are an effective component of a community-wide IPM program.

Even as the current linear value chains (LVC) of organic waste and animal feed hold the potential to become circular, these practices continue to pose major environmental risks such as deforestation and overfishing. Therefore, a novel circular value chain (CVC) is proposed, connecting the organic waste stream with animal feed production by the use of insect-based organic waste conversion technology. The Black Soldier Fly (BSF) is chosen as the insect-based conversion technology since it has nutritional properties, which serves both waste treatment and animal feed material production purposes.

Abstract:

The present study aims to investigate the diversity and flight activity of Staphylinidae in a citrus orchard of the Catania Plain (Sicily) using different sampling methods (car-net, window traps and pit-fall traps). The study looks at the complex of flying rove beetles with the aim of defining preliminarily the faunistic and zoogeographical structure of this family in the study area. A second aim of the study is to investigate, using window-traps and pit-fall traps, the spatial distribution of flying staphylinids inside the orchard and in adjacent habitats. The use of window traps and car-net

Son originalité réside dans la prise en compte des pratiques agricoles, et non pas uniquement de la quantité d'habitats semi-naturels, pour évaluer l'impact de l'intensification agricole. A l'échelle de 14 sites européens, les abeilles sont affectées négativement par l'intensification agricole (mesurée par la quantité de pesticides et fertilisants azotés et par la charge en bétail) et positivement par la quantité d'habitats semi-naturels. A l'échelle du paysage, nous avons montré

Les changements climatiques ont des impacts considérables sur le temps, les océans et les rivages, la vie sauvage. Ils amènent des problèmes désormais considérés comme majeurs par les gouvernements et organisations internationales. Ces efforts ont fourni un cadre à cette thèse, qui propose de procéder en boucle fermée de l’observation d’insectes ravageurs, avec des centaines de capteurs en réseau ("light traps"), au système d’information, et enfin à des décisions de lutte, manuelles ou automatiques. Le point d’appui pratique est la conception d’un système de comptage d’insectes proliférant dan

Abstract:

L'utilisation thérapeutique de glycoprotéines recombinantes produites dans le système baculovirus-cellules d'insectes reste limitée par le potentiel de glycosylation de ces cellules, qui produisent essentiellement des structures O- et N-glycanniques courtes. Notre travail s'inscrit donc dans un effort global d'"humanisation" de la glycosylation des protéines produites dans les cellules de Lépidoptères.<br />Nous nous sommes d'abord attachés à comprendre la voie de maturation des N-glycannes dans des cellules Sf9.

Abstract:

Pine processionary moth (PPM, Thaumetopoea pityocampa) is an active range expanding pest species having significant economic impact in terms of tree growth and public health. A lot is known about its natural history although one important aspect of its life history, diapause, has been so far neglected in spite of its acknowledged importance in pest establishment and dynamics. A few questions related to diapause have been addressed in this PhD project. Although the existence of prolonged diapause (PD) was reported long ago, no study provided its maximum duration. We provide evidence of existe

La faune des bousiers des hautes montagnes du Mexique a été encore très peu étudiée. Des travaux ponctuels avaient été réalisés pour certaines montagnes, mais une analyse approfondie et simultanée de plusieurs massifs montagneux n'avait jamais été faite auparavant, en particulier avec une double approche, écologique et historique. Les chaînes montagneuses sont des systèmes extrêmement favorables pour analyser les influences biogéographiques et les interactions écologiques dans les assemblages d'espèces.

Abstract:

We are currently faced with the global challenge of conserving biological diversity while also increasing food production to meet the demands of a growing human population. Land-use change, primarily resulting from conversion to production land, is currently the leading cause of biodiversity loss. This occurs through habitat loss, fragmentation of remaining natural habitats, and resulting edge effects. Land-sparing and land-sharing approaches have been discussed as alternative ways to engineer landscapes to mitigate biodiversity loss while meeting production objectives. However, these represen
