The 15-day Jumpstart was developed as an evidence-based, affordable, standardized, replicable, and scalable program, designed to demonstrate quickly to patients that changing what they eat can improve their health. The program was designed using the principles of the self-determination theory of motivation and personality. Patients were instructed to eat an Esselstyn-compliant, whole-food plant-based diet consisting of vegetables, fruits, whole grains, and legumes. Of the 389 participants in the program from September 2018 to February 2020, average weight loss was 5.8 pounds (7.3 for those whose body mass index was >30), average systolic blood pressure drop was 6.8 points (16.8 points for those with systolic blood pressure >140), average drop in cholesterol was 26 points (44 points for those with a cholesterol >200), average drop in low-density lipoprotein was 19 points (33 points for those with a low-density lipoprotein >100), and average drop in fasting blood sugar was 5.1 points (28.4 points for those starting in the diabetic range); P value was <.005 for fasting blood sugar and <.001 for all other comparisons. A 15-day program that helps patients adopt an Esselstyn-style whole-food plant-based diet, through education, individualized medical feedback, social support, and facilitated small group work, rapidly improves health.

The Given

Studies of the food-plant associations of Heliothis armigera have elicited the information that, for all practical purposes, egg-laying may be considered as confined to the period of florescence. Evidence of coincidence of the oviposition and flowering curves is submitted for 21 species of short-flowering crops and 8 species of long-flowering crops. All told, records taken in nearly 1,000 crops have been consulted for the conclusions drawn.As regards short-flowering species, the peaks, as well as the confines, of the oviposition and flowering curves are related closely. But oviposition on long-flowering species may decline while flowering is still in progress, or two or more waves of oviposition may be evident according to the number of moth flights spanned by the flowering period. The courses of oviposition on long-flowering species of crop in the given instances are interpreted through knowledge of the train of moth flights: although egg-laying in quantity occurs within the flowering period, peak layings frequently are not aligned with maximum flower production because the calendar times of moth flights are displaced in relation thereto.

Arthropod Species

About 10,000 arthropod species live as ants' social parasites and have evolved a number of mechanisms allowing them to penetrate and survive inside the ant nests.Myrmicacolonies, in particular, are exploited by numerous social parasites, and the presence of their overwintering brood, as well as of their polygyny, contributes to make them more vulnerable to infestation. Butterflies of the genusMaculineaare among the most investigatedMyrmicainquilines. These lycaenids are known for their very complex biological cycles.Maculineaspecies are obligated parasites that depend on a particular food plant and on a specificMyrmicaspecies for their survival.Maculinealarvae are adopted byMyrmicaants, which are induced to take them into their nests by chemical mimicry. Then the parasite spends the following 11–23 months inside the ants' nest. Mimicking the acoustic emission of the queen ants,Maculineaparasites not only manage to become integrated, but attain highest rank within the colony. Here we review the biology ofMaculinea/Myrmicasystem with a special focus on some recent breakthrough concerning their acoustical patterns.

Alternative Food

As Mr. Grote has done me the honour to make certain criticisms on some of my recent papers, I would ask space for a brief reply.In regard to Gortyna Ærata,I have no doubt that it has an alternative food-plant, but possibly it may never be discovered. Mr. Bird has made the same point, that as burdock is an introducted species it could not be the original preferred food-plant of any American species. But, while I admiit that an introduced species could not be the original food-plant of an American insect, I see no reason why it should not be the preferred food since its introduction, just as Doryphora Decemlineata prefers the potato to its original food-plant.
