Exploring protandry and pupal size selection for Aedes albopictus sex separation [PDF]
Background: We explored the possibility to improve male/female separation (sexing) in Aedes albopictus by selection of two strains, one toward increasing sex dimorphism and another toward increasing protandry.

Silencing of two insulin receptor genes disrupts nymph-adult transition of alate brown citrus aphid [PDF]
Insulin receptors play key roles in growth, development, and polymorphism in insects. Here, we report two insulin receptor genes (AcInR1 and AcInR2) from the brown citrus aphid, Aphis (Toxoptera) citricidus.

Wing Dimorphism in Weevils [PDF]
IN a reference which appeared in NATURE of July 28, p. 144, to my paper on the inheritance of long and short wings in the weevil, Sitona hispidula (Trans. Boy. Soc. Edin., vol. 55, part 3, No. 27), a statement occurs which it is desirable to correct. It is stated in the note that evidence from breeding indicates that the abnormal condition of the wing ...

Wing sexual dimorphism in Aedes fluviatilis (Diptera: Culicidae)
Culicidae mosquitoes are important vectors of pathogens; however, males and females have different responses to selective pressures, leading to distinct evolutionary outcomes. A better understanding of this phenomenon is crucial to establish effective control strategies for this mosquito.

Are there sex differences in the body size of the Eurasian red squirrel in Slovakia? [PDF]
Sexual dimorphism of the Eurasian red squirrel on five somatic variables (head-and-body length, tail length, hind foot length, ear length and body weight) was evaluated on 55 squirrels.
