TL;DR: Quality was affected to the extent that federal support prices for four varieties were reduced even at the lowest infestation which averaged between seven and eight stink bugs per 1,000 panicles.
Abstract: Studies were conducted during 1960 and 1961 to evaluate effects or rice stink bug ( Oebalus pugnax (F.)) infestations on rice in Louisiana. Five varieties of rice grown under screened cages were infested during the early heading stage with adults and late-instar nymphs. Infestation levels were varied to determine effect on quality and yield. Quality was affected to the extent that federal support prices for four varieties were reduced even at the lowest infestation which averaged between seven and eight stink bugs per 1,000 panicles. Consistent and severe losses in yields resulted from infestations which averaged approximately 230 or more bugs per 1,000 panicles. Viability of kernels was lowered by injury resulting from stink bug feeding. Greatest reductions occurred in damaged kernels which were injured in the germ region or which were severely atrophied.

TL;DR: Temporal and geographic variations in infestations of Lepeophtheirus salmonis and Caligus elongatus are described from two species of farmed salmonids, Salmo salar L. and Oncorhynchus mykiss Walbaum.
Abstract: In order to evaluate the performance of various sea lice management strategies, data sets from a number of salmon farm sites on the west coast of Ireland were examined. These data sets were collected as part of the ongoingNational Sea Lice Monitoring Programme in Ireland. Temporal and geographic variations in infestations of Lepeophtheirus salmonis and Caligus elongatus are described from two species of farmedsalmonids, Salmo salar L. and Oncorhynchus mykiss Walbaum. Patterns of lice transmission, both within and between fish populations, are discussed and environmental and biotic influences considered. Clear differences in infestation parameters, which persist over a number of seasons, are identified between sites. Where infestation parameters are observed to change over successive seasons, these are linked to changing husbandry practices.

TL;DR: Hermetic storage of common beans is an effective tool in the control of A. obtectus; there was a significant increase in infestation in the grains in non-hermetic storage (control); the quality of the beans correlated with infestation; it was not altered in the hermetic storage systems and decreased in thecontrol sample.

TL;DR: This work shows that this species has the ability to oviposit and develop in healthy strawberry fruit with and increased infestation level when the fruit has damage to its epidermis.
Abstract: Drosophila suzukii (Matsumura) has been recently detected causing damage to strawberries in Brazil. Infestation in strawberry culture has often been observed jointly with the presence of Zaprionus indianus Gupta. This study investigated the susceptibility of strawberries at three ripening stages to infestation of D. suzukii and Z. indianus and their interaction. In the laboratory, strawberries cv. Albion at different ripening stages (green, semi-ripe and ripe) were exposed to D. suzukii and Z. indianus for 24 h in choice and no-choice bioassays. Additionally, we evaluated the effects of mechanical damage incurred artificially or by D. suzukii oviposition on Z. indianus infestation. In no-choice bioassay, there were no significant differences in fruit susceptibility to D. suzukii infestation at different ripening stages. However, in choice bioassay, D. suzukii adults preferred to oviposit on R fruit. The presence of mechanical damage did not increase susceptibility of fruit to D. suzukii oviposition. For Z. indianus, there was greater susceptibility of R fruit in relation to SR and G fruit in both the choice and no-choice bioassays. There was a significant and positive interaction of mechanical damage and damage caused by D. suzukii to R fruit and infestation by Z. indianus, which was not observed in SR and G fruit. Although infestation of Z. indianus is related to attack damaged or decaying fruit, this work shows that this species has the ability to oviposit and develop in healthy strawberry fruit with and increased infestation level when the fruit has damage to its epidermis.
