Impact of the Parasitoids (Howard) and (Förster) on Three Pests of Stored Rice.

This study evaluated the ability of pteromalid parasitoids and reared on to control stored product coleopteran pests , and . In trials of parasitoid treatment with , fewer pests ( and ) emerged than in the control. Parasitoid reproduction was highest with as a host, followed by and .

Control of with the Predatory Mite .

In this study, the predatory mite (Acari, Phytoseiidae) was tested for the control of the tomato russet mite (TRM) (Acari, Eriophyidae) in experiments with small plants, under semi-field and crop conditions. The releasing strategy consisted of repeatedly introducing the predator together with additional breeding prey. The predator was able to move and disperse to the upper part of the tomato plant where the TRM seeks refuge.

Nonreproductive effects are more important than reproductive effects in a host feeding parasitoid.

When female host feeding parasitoids encounter a potential host, they face a complicated trade-off between either laying an egg for investing in current reproduction or feeding on or killing the host for future reproduction. Few studies have measured these behavioral shift patterns in a given host-parasitoid association thus far. We systematically assessed the behavioral shifts and life history traits of a host feeding parasitoid, Necremnus tutae, on different instars of its host Tuta absoluta.

Similar Bacterial Communities among Different Populations of a Newly Emerging Invasive Species, (Meyrick).

Microorganisms in the guts of insects enhance the adaptability of their hosts with different lifestyles, or those that live in different habitats. is an invasive pest that is a serious threat to tomato production in China. It has quickly spread and colonized Xinjiang, Yunnan and other provinces and regions.
