Spatial synchrony of population fluctuations has major consequences for the impacts of forest insect pest outbreaks at regional scales. We tested the predictions that the strength and drivers of this synchrony would differ among species according to their dispersal abilities and feeding guilds.

Life History, Damage, and Gall Development of the Gall Midge, \u3ci\u3eNeolasioptera Brevis\u3c/i\u3e (Diptera: Cecidomyiidae), Injurious to Honeylocust in Michigan [PDF]
Neolasioptera brevis is univoltine in Michigan. Adults issue in late spring, and females deposit eggs in rows on the lower side of young shoots of honeylocust. Larval eclosion occurs shortly after: there are three larval instars.

Understanding how cooperative interactions remain stable matters for biodiversity because many plants rely on specialist insects that can also impose reproductive costs. We studied the interaction between Sambucus sieboldiana and seed‐consuming Heterhelus beetles through detailed field observations and pollination experiments.

Residual Efficacy of Lufenuron (Instar®), 1994 [PDF]
Abstract Residual effect of a new chitin synthesis inhibitor, lufenuron (Instar® 0.2 TB) was determined against three different nymphal ages of German cockroach (1-week, 3-week and 5-week) and American cockroach (1-week, 5-week and 10-week).

Jumping plant-lice of the Paurocephalinae (Insecta, Hemiptera, Psylloidea): systematics and phylogeny [PDF]
Much confusion exists with respect to the content and definition of the psyUid subfamily Paurocephalinae. Based on a cladistic analysis of 22 morphological characters (16 adult and 6 larval), the subfamily is redefined to comprise the following five ...

Experimental setup for dsRNA feeding in Brassicogethes aeneus to evaluate the effect of a synthetic polymer nanocarrier on RNAi efficiency. The experiment assessed whether the nanocarrier enhances RNAi after oral dsRNA delivery. (a) Stability of dsRNA–nanocarrier complexes was tested in simulated gut conditions. (b) Gene expression of αCOP and dre4 was
