TL;DR: There were substantial losses in thiamine, riboflavin and niacin contents of wheat, maize and sorghum grains at three infestation levels (25, 50 and 75%) caused by releasing two insect species viz., Trigoderma granarium and Rhizopertha dominica separately and mixed population.

TL;DR: Effective control measures are needed to control and prevent such ectoparasite infestation amongst children.
Abstract: The infestation status of head louse among children attending primary schools and kindergartens in Chinju-shi, Kyongsangnam-do, Korea, was investigated between June and July 1999. Out of 2,288 children examined, 3.9% of boys (48/1,242) and 23.5% of girls (246/1,046) were infested with nits or adult/nymphs of lice. The effectiveness of lindane shampoo (1% gamma benzene hexachloride solution) was evaluated after one or two time applications to all the children infested. The negative conversion rate of pediculosis was 93.5%. Effective control measures are needed to control and prevent such ectoparasite infestation amongst children.

TL;DR: Gypsy moth larvae and pupae were collected in 1st cycle populations along the leading edge of the infestation in Pa. from 1974–1977 and much higher rates were detected in the post-culmination phase.
Abstract: Gypsy moth larvae and pupae (91,902) were collected in 1st cycle populations along the leading edge of the infestation in Pa. from 1974–1977. More than 14,600 parasites were recovered. Parasite associations with pre-culminating, culminating, and post-culminating host populations are given. B. pratensis was recovered most frequently during the pre-culmination phase, B. intermedia during the culmination phase and P. silvestris during the post-culmination phase. Relatively low rates of parasitism were observed in the pre-culmination and culmination phases. Much higher rates were detected in the post-culmination phase. Parasite effectiveness is discussed.

TL;DR: Although hemlock typically occurs in deeply shaded forests, the results suggest that silvicultural treatments such as forest thinning that increase light exposure may reduce HWA abundance and lead to better tree C balance, and may be an effective component of large-scale conservation and restoration strategies.
