Though extra instars are often associated with poor conditions and thought to be a compensation for a low growth rate, the reasons why they are necessary, and for variable instar number existing under standard rearing conditions, are not yet clear.

Insects and Survival: A Review of Primary and Secondary Defense Strategies
Based on a review of three decades of literature, insect defense mechanisms are classified into primary (I) and secondary (II) mechanisms of behavioral, morphological, and chemical nature. These mechanisms have been recorded in 22 (I) and 20 (II) orders, respectively.

Preliminary taxonomic study of the genus Praon (Hymenoptera: Braconidae: Aphidiinae) and its host associations in Iran [PDF]
In the current study, the information on occurrence, distribution and host aphid-plant associations for the species of Praon Haliday in Iran are presented. Eight species of Praon were found in the areas under study, which include four previously reported

Hamiltonella defensa infection increases honeydew production in certain aphid genotypes, potentially modifying aphid feeding behaviour. Parasitoid wasps, Aphidius ervi, are more attracted to honeydew from H. defensa‐infected aphids; though larger honeydew amounts may slightly deter searching.

Three new records of the genera Leiophron and Euphorus (Hym.: Braconidae: Euphorinae) from Iran [PDF]
The parasitoid wasps of the genera Leiophron Nees and Euphorus Nees were studied in northern Iran (Guilan, Mazandaran and Alborz provinces). The specimens were collected using Malaise traps from different habitats during 2010-2011.

A protracted phenology: Post‐diapause larval development of a threatened butterfly
Larval survival during diapause was high; hibernaculum webs were mostly located near Succisa pratensis plants, which often retained vital leaves through winter. Post‐diapause developmental time varied strongly depending on exposure to different microclimates, being reduced by litter cover, solar radiation and a higher heat load index.

ABSTRACT The use of insectary plants to provide alternative food and shelter resources for enhancing natural enemy activity has been established as a common practice in IPM. Candidate flowering plant species have been screened and evaluated for their contribution to enhance life parameters of beneficial insects.
