Development of the solitary parasitoidApanteles sp. groupultor in larvae ofEctomyelois ceratoniae was investigated at different constant temperatures. Temperature had a significant effect upon parasitoid development during both host-internal and host-external phases. The duration of the host-internal phase varied from 41 days at 15–17°C to 8.6 days at 29°C, the duration of the host-external phase varied from 16.5 days at 16–17°C to 5.4 days at 29°C.Effect of photoperiod upon parasite…

The progeny production of a hymenopterous parasitoid,Apanteles sp. groupultor, as affected by temperature

The range of constant temperature did not greatly alter the progeny sex ratio when female parent had been mated, but male activity was adversely affected when both sexes were exposed to it without previous mating, resulting in a higher number of male progeny.

Carob Moth, Lesser Date Moth, and Raisin Moth

This chapter provides an in-depth coverage of the carob moth, lesser date moth, and raisin moth, with particular emphasis on their distribution, natural history, and management in date gardens.



Developmental Biology of Apanteles yakutatensis (Hymenoptera: Braconidae), a Primary Parasite of Autographa californica (Lepidoptera: Noctuidae)

The developmental biology of Apanteles yakutatensis, a primary, gregarious, larval endoparasite of Autographa californica, was investigated and there was a weak negative relationship between number of parasite larvae per host and mean weight of parasite adults.

Biology and physical ecology of Apanteles subandinus Blanchard (Hymenoptera: Braconidae), with notes on temperature responses of Apanteles scutellaris Muesebeck and its host, the potato tuberworm

Comparisons of the temperature responses of the two parasites and their host revealed that the parasites have a higher power of increase than the host, and that A. scutellaris is better adapted to high temperatures than is A. subandinus.

Reproductive Biology of Telenomus californicus Ashmead, an Egg Parasite of the Douglas-fir Tussock Moth: Laboratory Studies

We describe effects of mating, female age, photoperiod, host storage temperature, and host availability on reproduction of Telenomus californicus Ashmead (Hym.: Scelionidae). Reproduction is

Parasites ofEctomyelois ceratoniae with biological studies onApanteles sp.Group ultor in Iraq

The parasitization percent was increased from 10 % during April to 35 % at the end of the pomegranate fruiting season at October, and female parasite preferred to infest the host larvae at the age of, 2–3 days than 7 day old.

Cardiochiles nigriceps (Hymenoptera: Braconidae): Development Time and Fecundity in Relation to Temperature

Development of Cardiochiles nigriceps Viereck in Heliothis virescens (F.) was determined at constant and fluctuating temperatures and the number of larvae parasitized per female per day increased.

Culturing the Carob Moth, Ectomyelois ceratoniae (Zeller) (Lepidoptera: Pyralidae), on an Artificial Diet

Adaptation of a population of the carob moth, Ectomyelois ceratoniae (Zeller), to laboratory rearing conditions takes six generations. Average larva and pupa periods were 17 and 7 days, respectively;

Temperature-Dependent Development of Greenhouse Whitefly and Its Parasite Encarsia formosa

The thermal threshold for greenhouse whitefly, Trialeurodes vaporariorum, and the developmental times, in day-degrees above 8.3°C, for the egg, 1st-, 2nd-, 3rd-, and 4th-, instar nymphs should enable growers to predict when to release E. formosa and when to apply pesticides with minimal effects to the parasite population.

Effect of Various Temperatures upon Rate of Development of the Cabbage Maggot under Artificial Conditions

The effect of temperature on the development of Hylemya brassicae (Bouchae) was determined by use of plant-growth chambers at temperatures ranging from 50 to 80°F with thermocouples placed at the

Temperature requirements of some aphids and their parasites

The rate of insect development depends upon the temperature to which the insects are exposed. For each species, the temperature below which no measurable development occurs is its threshold of
